References SABR Experiments To assess a real-world application of DRL hedging, agents are trained using marketcalibrated stochastic volatility model paths. Recall however that to establish a baseline, a first experiment uses arbitrary model coefficients. For this initial experiment, Exhibits 11 and 12 show the final P&L distributions of the DRL and BS Delta strategies under 0% and 3% transaction costs, respectively, and Exhibit 13 shows the summary statistics of both cases. The results are consistent with the GBM experiments, showing that under transaction costs, the DRL agent outperforms the BS Delta strategy, producing a higher mean final P&L and a lower standard deviation. The real-world application may now be examined using the DRL agents trained with market calibrated models. To present results without listing all 80 options, the mean and standard deviation of mean final P&L result across five strikes for each symbol and maturity date is computed. These final P&L statistics for both the DRL agent and the BS Delta strategy are summarized in Exhibit 14 for a transaction cost-free scenario, and in Exhibit 15 for a 3% transaction costs. The reader should not compare results between different rows, as the results are functions of both symbol prices and maturities. The DRL and BS Delta final P&Ls statistics for all 80 options are listed in the Appendix. When there are no transaction costs, both the DRL agent and the BS Delta strategy achieve near-zero means in all cases, indicating effective hedging performance. These results show that the DRL strategy achieves a higher mean final P&L in all 16 cases, while the BS Delta strategy yields a lower standard deviation in all cases. With a 3% transaction cost rate, the results indicate that the DRL agent achieves a higher mean of mean final P&Ls across the five strikes than the BS Delta strategy in all but one symbol and maturity date combinations (NVDA 11/17/2023). Moreover, the DRL agent achieves a lower mean standard deviation in 11 of 16 cases, exemplifying that the DRL agents hedge in a consistent manner that achieves a lower variance on average than a BS Delta strategy. This outcome implies that when transaction costs are incorporated, training a DRL agent with calibrated stochastic volatility model parameters is more effective than computing a BS Delta hedge using the model-derived volatility at each time step. Now, the DRL agent is tested on the empirical asset price data between the sale and maturity dates. Note that as the experiment aims to assess only the performance of the DRL agent in a realistic scenario, only an environment with a 3% transaction cost rate is used for testing. Exhibit 16 summarizes the mean final P&L for both the DRL agent and the BS Delta strategy across the five strikes for each symbol and maturity. Again, results should not be compared across rows, as the results are a function of both the underlying asset price process and the maturity date. The final hedging P&L for all 80 options using the true asset paths are listed in the Appendix. Using the actual asset paths for testing, the DRL agent outperforms the BS Delta strategy across the five strikes in 12 of 16 instances. As such, this outcome shows that not only do DRL agents achieve strong performance under simulated asset paths, maintaining consistency with the stochastic volatility model employed during training, but DRL agents also possess a desirable robustness in effectively hedging against empirical stock price movements. This is an important result, as it shows that on any given day, observed option prices may be used to train a DRL agent capable of hedging said option. Consider, for example, a trader with a basket of 80 options: the results from this work suggest that this trader can train a DRL agent for each option and achieve better performance than a BS Delta strategy. As such, a worthwhile future direction for this research would be to train the DRL agents anew on each day given the observed option prices. Further, as DRL becomes more prevalent in the hedging space, a worthwhile next step could be a parametric study that evaluates the impacts of various training hyperparameters such as the learning rates, episodes, re-balance steps, batch sizes, and reward functions. As there is currently no consensus in the DRL hedging literature towards hyperparameters and training best practices, this future study would help provide key information for practitioners attempting to employ their own DRL agents.

Evaluating Deep RL Agents in Hedging with Market-Calibrated Stochastic Volatility Models 

is a multi-tool component that keeps a company afloat through many channels and approaches. It is a multiverse of metrics–you just have to find what works for you. But how do you decide whether to stick with proven approaches or follow the latest trends? The truth is, the nature of the digital landscape is ever-changing and you can never really know when the latest marketing obsession will once again become obsolete. It’s just the nature of things and in 2024 we all have to deal with it. The good news is that the overall trends are not as fleeting as they might seem, and keeping up to date with forecasts for the upcoming months can give your business the much-needed push to catch your audience’s attention in the highly competitive field. Now, few things seem to be especially prominent amongst marketing trends right now, but before we dive headfirst into modern marketing, let’s recap the basics. Marketing Why should you care? While sticking to the “if it ain’t broke, don’t fix it” philosophy certainly has its benefits, in the modern day and age staying up to date is imperative to building a successful business. Your audience has ever-changing and evolving preferences, and your competitors continually explore new strategies to see what works and what doesn’t. If you want to stay relevant, you have to put effort into understanding what "staying relevant"  in your field means. Is it creating an AI campaign for a new feature or partnering up with a user for an honest review? Your competitors reside in the same limitless space as you do–the internet, the main thing that drives progress and competition. There is plenty of useful information getting out daily, the question is: who is going to get there first? First, set your priorities In response to the very dynamic nature of social media marketing, brands are now ready to focus their attention on platforms that closely align with their goals and audience preferences. Now, that doesn’t mean you should abandon all channels except one; the goal is to prioritize a few and keep the rest low-key because having a prominent social media presence is the hallmark of good, recognizable branding. You can save time and target a specific platform instead of many, like spending your time and money on campaigns when your audience spends most of their time on . Instead, create engaging YouTube videos, showcase product demos, collaborate with influencers, build a strong presence through community engagement, and curate visually appealing content on Facebook YouTube Instagram. This is just an example, and the way you do it will be unique to your product and your goals. By identifying your priorities you can direct your attention where it needs to go, effectively reaching and engaging your audience, driving brand awareness and sales in a competitive market. Now that your priorities are set, we can get into the upcoming trends. The creativity of AI In recent years the creativity of AI has gotten truly mind-blowing. With the recent we have seen a new horizon for the creative potential of AI. While this specific tool is not released just yet, there are plenty that can help you in the process of content generation. Major brands are already collaborating with AI to create new-age marketing campaigns. , which ended up winning at the Drum Awards Festival, an annual global competition for marketers. And Nike allowed their customers to –powered by AI. , unveiling of Sora Heinz launched one with DALLE-2 design their own unique pair of shoes There are plenty of examples out there. Big companies are using artificial intelligence not only for content creation but for ideation and strategy too. There are research assistants, generative apps, tools that can enhance resolution and ones that can make up a whole marketing strategy. Can it replace a whole marketing team? Probably not, but AI will for sure become a much more present trend in the coming years. Yet, here you’ll have to be more careful since to downrank AI-generated summarized content. Google is already implementing measures User-generated content In contrast to using machines to do the work, chances are we will be seeing much more user-generated content in the near future. There’s already plenty of it, and according to the brand engagement rises by 28% when consumers see both brand and user-generated content, and user-generated videos gain 10x views than brand videos posted on YouTube. It’s expected–we trust people, and a human presence in a campaign makes it much more trustworthy. Statistics can back this up–85% of users find user-made content more influential than branded content (also according to the Gitnux report). These days creating a tikTok with a creator raving about your product is more likely to get you more reach than placing a billboard on Times Square. As you can see, an unpolished video can have more benefits than a perfectly crafted campaign. It’s authentic, and that’s its main allure. It also has to be done right. A big part of this is generating an environment that will eventually build a strong brand community. Regular communication and giveaways will make your users more likely to want to take part in creating content for you. And when they do, reward it! It’s already a very cost-effective tool, so you can direct your resources towards supporting this type of engagement. But if you choose to use this approach for your business don’t make it feel plastic. The modern consumer is overwhelmed with content and will be able to easily distinguish real from fake. Gitnux Marketdata report Micro-Influencer Marketing On the road to authenticity, brands are now scaling down their collaborations with influencers. In the past years, we’ve seen it all and a brand deal from a celebrity is now simply a given in the media space. But the market is oversaturated and brands are looking for new ways to engage the same audiences by slightly changing their approach. The by the Influencer Marketing Hub highlights a notable preference among marketers and businesses towards collaborating with nano- and micro-influencers. The reason is simple–higher engagement rates. Why? Because smaller-scale influencers seem more trustworthy. And, this strategy is much more cost-effective for the brand. 2024 State of Influencer Marketing report Partnership Marketing Competition is the driver of progress. But what if you make your rivals (or just brands that you probably share an audience with) your collaborators? You already have so much in common: your audience and your goals. That’s enough to entertain the idea of partnership marketing to help both of your brands grow and reach new customers. Imagine the value you bring–doubled. This approach also allows you to cut costs, share resources, and exchange ideas with other teams. luxury brands partner with hotels, tech companies collaborate with cafe chains, and retail stores are more than happy to spice things up by introducing a non-profit company special offer. Brands do this all the time; High-quality content No matter which direction you go, high-quality content will remain a priority. We’ve all seen how annoying those extremely low-quality mobile ads can get. While this can get users’ attention, forget about it positioning your company as a respectable brand. These days humanity is overwhelmed with the amount of content that is up for consumption and so much of it is not at all well-made. It’s an opportunity for you to earn customer loyalty by putting effort into every step of content creation: from ideation to execution. To further perfect your process you can conduct interviews with your potential customers to see what matters to them. This way you will be more attuned to your audience, so setting up an appropriate Tone of Voice and tailoring the type of content to your clients is bound to bring much better results. Your work is you An easy way to up the quality and effectiveness of the marketing content you produce is to remember that what you do is a reflection of who you are, and the way your brand communicates with its audience is a reflection of the values that lie at the core of your company. Treating your potential customers with respect by creating relevant, engaging, high-quality content will build a bond that is not achievable by dry marketing techniques and metrics.

Using Mobula to Fetch and Display Market Data For Assets

In this article, we would like to demonstrate how to build a small yet powerful scalping application that trades on the leading cryptocurrency exchange – Binance. The bot will be connected to Binance through XTRD FIX API to receive real-time normalized market data and to place/cancel orders. You can reuse this in your projects for free. source code Disclaimer: the bot is not a ready-to-use solution because it lacks risk controls and proper positions management. Although our R&D shows promising performance, do not expect to achieve the same results. Before we dive into the technical part, it’s worth explaining the logic behind the given trading bot. Scalping is a momentum-based trading style where positions hold for minutes or even seconds and then sell for profit (or small loss… a sacrifice to Mr. Market). When performed manually, it requires self-discipline, the ability to handle stress, make quick decisions, and act accordingly. Renko chart is one of the technical analysis tools that help reduce market noise and identify market trends more precisely. One of the authors of this article was introduced to Renko about 15 years ago and fell in love with it. To construct a single brick on a chart we should perform several simple steps: Define a brick size e.g. 10 points Define the price type to track. It can be bids, asks, trades, an average between the bid and ask, etc. Start tracking prices in real-time If the price changed more than 10 points, then form a new Renko brick in the corresponding direction. It is possible that the single price change can form more than one Renko brick. Here is our trading logic: Wait for a new Renko brick to be formed If it is an UP brick, then place a limit order to SELL with a price at the level of UP + 1 brick If it is a DOWN brick, then place a limit order to BUY with a price at the level of DOWN – 1 brick Continue monitoring the market for changing course or for execution If a newly formed brick changed its direction (this means that the price changed at least 2x of a brick size in the reverse direction), we should cancel our existing limit order and place another one with a new price and reversed direction. If the market moved in the direction we predicted, then our order gets executed and we should start over. Simply put, it is the good old “buy low, sell high” principle computerized and applied to crypto markets through XTRD FIX API. The bot itself contains several main components: Market data connector Trading connector Market data processor/Renko generator Simple OMS/EMS syste To make this technical-enough material more fun, we decided to build a small user interface to plot Renkos bricks and executions. Since all high-level details of implementation were discussed, let’s get started with the implementation part. To build Renko charts we need to establish a connection to a service called XTRD MD Feeder. It is responsible for disseminating real-time normalized market data from Binance (and other crypto exchanges) using FIX protocol. In comparison with WebSockets, FIX is faster and more reliable because it runs on top of a pure TCP/IP stack and has no additional intermediary layers. Using FIX protocol, you can easily subscribe to receive updates for one or many trading instruments available on Binance such as BTC/USDT, ETH/USDT, and so on. It is possible to specify what sort of information you’ll need – bids, asks, and/or trades. Another big advantage is that market data itself comes in incremental updates. This means that you receive only actual changes of the entire orders book (like 3-4 levels) but not a full book every time. This is not a big issue with Binance which already streams data as a delta (difference between the previous and current state) but can be extremely helpful with other crypto exchanges XTRD supports. There are three major messages defined by FIX standard and implemented inside XTRD that help manage your crypto market data streams – MarketDataRequest, MarketDataSnapshotFullRefresh, and MarketDataIncrementalRefresh. As it is easy to understand from their names, MarketDataRequest is used to manage your subscription (start or stop data streams), MarketDataSnapshotFullRefresh is used by the server to transmit the entire book, and MarketDataIncrementalRefresh is sent by the server when data (price or side) in the particular orders book changed. The market data management workflow is simple – once the application established a connection to XTRD OEMs over the FIX, it sends MarketDataRequest to subscribe to all updates on BTC/USDT (or another selected symbol) on Binance. If the request was successfully processed, XTRD OEMS for digital assets trading responds with a MarketDataSnapshotFullRefresh message that contains all levels for BTC/USDT orders book. The application uses this data to initiate the book and starts waiting for incoming MarketDataIncrementalRefreshes that carry small (and sometimes not very small) delta changes. These changes have to be applied to the book (delete levels, update sizes on a particular level, add new prices). Once a book is updated, the component responsible for Renko’s generation will check if the conditions to create a new brick are met or if the price is still within the interval. Now, when we have a working market data connection and Renkos charts, it’s time to start trading on Binance using FIX API. FIX specification contains plenty of different messages (commands and responses) that cover pretty much everything in a typical trade lifecycle starting from initiation to ending with trade confirmation and settlement. XTRD OEMS system allows managing orders (get all, place, cancel, replace) and viewing positions through the unified FIX API. When it comes to trading, there are three major messages – NewOrderSingle, OrderCancelRequest, and ExecutionReport. NewOrderSingle is used to initiate an order. The message allows specifying different order characteristics, such as side (e.g. BUY), size, type (e.g. LIMIT), symbol, time in force (e.g. Good Till Cancel), among others. Below is a textual representation of the raw FIX request to buy 0.001 BTC for USDT at Market on the Binance. In many cases, the server interacts with clients over ExecutionReports. This message is used to indicate changes of your orders over time – was it accepted or rejected, canceled, or executed, and if executed, what are the price and size? Each message has clear status, a clear ID, and a timestamp associated with it. Many exchanges have their own workflows. XTRD OEMS for digital assets trading helps normalize these statuses and make them identical across all supported platforms: Our demo application utilizes only two simple commands – NewOrderSingle (to place a new order) and OrderCancelRequest (to cancel an order we don’t need anymore). Another useful command is OrderCancelRequest. It is used to initiate the cancellation of a pending order or the outstanding amount of a partially filled order. Below is a sample of FIX-based OrderCancelRequest to cancel a pending order on Binance: Our demo application will send requests to open an order (using NewOrderSingle) and to cancel it (using OrderCancelRequest) over the FIX to Binance. The server will notify us (using ExecutionReports) in real-time about any status changes of our order(s). In real life, it’s always a good idea to separate business logic that makes decisions about entering or exiting the market from orders management. This component is usually complex and covers a vast array of scenarios of what can happen with orders starting from regular behavior when everything goes as expected and ending with different doomsday scenarios. For the sake of simplicity, in this sample, we decided to use oversimplified orders management which also handles incoming market data-related events (OMS.java). Below is the video of the working system (replayed with 50х speed): Building a successful trading system is a challenging task where you must overcome many obstacles. Our goal is to make sure that the connectivity between your application and target exchange (or exchanges) will not become one of these blocking factors. By using XTRD OEMS for digital assets trading, you can easily build a reliable system that can operate around the clock. Also published here .

Creating a Renko-based Scalper for Binance

“Virality isn’t luck. It’s not magic. And it’s not random. There’s a science behind why people talk and share. A recipe. A formula, even.” — Jonah Berger Do you still wait for the newspaper every day, not just for the news, but to fill up the latest crossword? The prospect of solving that piece of puzzle, one day at a time, gives many a sense of delight. Some people go jittery if they somehow miss a day; it has become part of their routine!! Know what has become a part of millions of people’s routines? It’s called Wordle. As you read, you’ll know what this latest internet sensation is and why it went viral. So, What Is Wordle? Wordle is a daily cryptic word game on the internet. A person needs to guess a five-letter English word in a maximum of six tries. The first try has to be a complete guess without any clues. Every word you guess, the game starts giving you clues for the answer word by changing the colour of the tiles in which the word is written. If a letter from your word exists in the answer word the letter tile turns yellow or green. Yellow indicates that letter present in the answer but it is not in the right position. Green indicates that the letter is present as well as it’s in the same position in the answer word. Image source: Wordle As you keep guessing, you should be able to crack the puzzle in six tries. What’s the Big Deal? Yeah yeah, we know you might be thinking, “what’s the big deal? It’s just a word game!”. Well, look at the number of players who played Wordle in: November 2021 - 90 January 2022 - 300,000 A week later - 2 million The numbers are rising every single day. In recent events, Wordle has been acquired by the New York Times in some undisclosed ‘seven figures’ and is now available to play on their website. Games like Wordle are amongst the key components of NYT’s marketing strategy. People loved Wordle so much, many alternate niche-based versions popped up. There is the very famous ‘Nerdle’ which is for maths lovers, Taylordle for Taylor Swift Fans aka Swifties, ‘Marketdle’ for marketers, and many more. As they say - it’s the best compliment if someone is copying you! The Origination/Love Story Like many great things, Wordle’s origin is connected to love. Josh Wardle (I love the name coincidence!), a Brooklyn-based software engineer, made this game for his partner, Palak Shah who loved cryptic puzzles. In the beginning, the game was available for just the two of them, but they later decided to open it up for their family. The family got hooked instantly and gradually through word-of-mouth many more people got glued to Wordle. What happened after is in front of you. Reasons Why Wordle Went Viral Wordle was not made with an intent to go viral and yet it managed to make a place in people’s hearts. Below are five reasons why Wordle went viral: Feeling of Agency - a principle of game theory Word-of-Mouth publicity Automated sharing of scores on social media especially Twitter FOMO - Fear of Missing Out Element of Scarcity Feeling Of Agency | Agency Expansion From the Game Theory perspective, a ‘Feeling of Agency’ refers to the feeling of control over actions and their consequences. In simpler terms, it is a feeling that drives you to continue making choices based on the positive results of your past actions. Almost all games have this ‘Feeling of Agency’ that drives the players. It is one of the strong reasons that drives people to continue playing any game. This feeling is quite strong in the case of Wordle. While playing the game, the first word is a completely random guess. All the guesses after that are based on the consequences of the previous guess. If a letter turns green, it means it’s in the right place of the answer word and hence you’ll continue placing it on that spot in all the next guesses. If a letter turns yellow, it means it is in the answer word but has to be placed somewhere else. In the next guesses, you’ll place it in different positions. With every guess - you narrow down your choices for the next attempt and get closer to the answer. The ability to get closer to the answer is actually the agency expansion. This sense of achieving something on one’s own, based on their own past actions; gives them a reason to continue playing Wordle. Word-of-Mouth Publicity There’s no better tool of marketing than Word-of-Mouth. Word-of-mouth was the strongest contributor to If someone likes something, they are going to tell it to others one way or the other. Unlike other forms of marketing, word-of-mouth is more credible as it comes from someone who has tried and tested what they are referring to. I heard of Wordle from 3-4 different people - once from our writer, once from a client who created their own version of Wordle called Marketdle, and more. Later I checked with my friends and acquaintances in WhatsApp groups and most recommendations came from friends or community. Hence word-of-mouth validated :) the virality of Squid Game as well. Automated Sharing of Scores Wordle’s score-sharing feature is the biggest reason for it becoming an internet sensation. Once you finish solving a puzzle, Wordle gives you an option to share the achievement with the help of colourful square-shaped grids. Without sharing the actual answer, one could showcase their achievement. These grids tell how the player managed to get the answer and how many tries it took him. Image source: Twitter Social media feeds started being bombarded with these square grids. Other than just solving Wordle daily, people became habitual of sharing their scores on their social media. From Instagram and Facebook stories to tweets, the grids were everywhere. Twitter alone clocked 3 million Wordle tweets just between 23rd December 2021 and 27th January 2022. FOMO - Fear of Missing Out The Feeling of Missing Out aka FOMO is the worst feeling ever. Once those colourful square grids started popping up on everyone’s feed, people who didn’t know anything about it started feeling left out. Not just these colourful score grids but there were memes about Wordle. Companies started using Wordle elements in their social media posts. It was as if everyone was going crazy about these green and yellow grids. That sheer idea drove many people to at least try the game and see for themselves. If they liked it, they kept coming back and spreading the word. Image source: Twitter Element of Scarcity Anything that is scarce is valued. It applies to games too. If you were given unlimited word puzzles to solve in a day, no matter how much you loved them, you'd get bored. But if there was just one puzzle a day, and you had to wait for twenty-four hours to solve the next one, you'd be hooked. That’s why crosswords and sudokus in newspapers are still solved with so much fervour. Wordle leveraged this element of scarcity to its benefit. There is just one puzzle a day that leaves you wanting for more once you finish it. There’s also a ‘streak’ feature that tells people the number of days they have been continuously playing Wordle, which makes them not miss a single day. If they miss, they lose that streak. Wrap Up: Why Did Wordle Go Viral? Wordle’s story is fun, exciting, loving, and inspiring for many disciplines. The feeling of agency inspires game creators to add elements of agency to bring people back again and again to the games. Word-of-mouth is still one of the strongest ways to make things go viral. But it works only if you give people a reason to talk about your creation whether it’s a game like Wordle or a series like Squid Game. Social media marketing can do wonders for your product if leveraged correctly. With this, we leave you to think about how you can make your creation a sensation.

Wordle: How the Latest Internet Sensation Went Viral

How to Build a Directed Acyclic Graph (DAG) - Towards Open Options Chains Part IV

In this post, we develop the essential code for extracting, transforming, and loading options data. We will need to retrieve data from the TD Ameritrade API, transform it, and load the data into the PostgreSQL database we created in . We will also run some checks to ensure that the pipeline works. Part I: Designing the Database The Series This is the second post in my series, : Towards Open Options Chains: A Data Pipeline Solution Database Design Foundational ETL Code Getting Started with Airflow Building the DAG Containerising the Pipeline Pre-requisites Operating system: Linux (I'm using Ubuntu 20.04). If you're on Windows, consider using [1]. Windows Subsystem for Linux Python 3.9 with the following packages/libraries and their dependencies installed: , , , and requests python-dotenv pandas psycopg2 Recap of Use Case The use case for the data is to run backtests of options trading strategies. Therefore, the data pipeline must collect sufficiently fine-grained data for us to do backtests. This means we'll need options prices, volumes, and the options greeks (e.g. delta, theta, and gamma), collected at sufficiently high frequency. Extract The first step in our pipeline involves the data. In our case, we will retrieve data from the . extracting TD Ameritrade (TDA) Option Chains API First, we will obtain credentials for using the API by doing the following: Head on over to the to sign up for a free account. TD Ameritrade developer site Go to and create an app. My Apps Note the , which is used for OAuth 2.0 token-based authentication. Consumer Key Next, we construct requests to the TDA Option Chains API in Python. We define a few parameters: We assume that we have a file ( ) in the same folder containing your API key in a variable . We will load it into Python using . Your API key: .env API_KEY=<your API key here> python-dotenv For now, we'll use Facebook (FB) as an example. Ticker: We need to specify the instrument too. For now, we query the data for puts only. Instrument: This defines the total number of strikes to be returned. We'll go for 50 as a start, but we should decrease this number to the minimum necessary to optimise storage costs. Strike Count: This refers to whether the options are in-the-money (ITM), out-of-the-money (OTM), etc. We'll request all of them. Range: We specify a start date and end date using Python's built-in module. I've chosen to use the current date as the start date and the day 45 days out as the end date. Date range: datetime That gives us the following: # Import modules
import json
import requests
from dotenv import dotenv_values

# Load environment variables - API key is accessible at env['API_KEY']
env = dotenv_values('.env')

# Configure dates
start_date = datetime.today()
end_date = start_date + timedelta(days=45)

# Other params
TICKER = 'FB'

# Configure request
headers = {'Authorization': ''}

params = (
    ('apikey', env['API_KEY']),
    ('symbol', TICKER),
    ('contractType', 'PUT'),
    ('strikeCount', '50'),
    ('range', 'ALL'),
    ('fromDate', start_date),
    ('toDate', end_date),
) We now use the library to send the request with the defined headers and parameters, receiving a JSON response with the options chain if all went well: requests # Get data
response = requests.get(
    'https://api.tdameritrade.com/v1/marketdata/chains',
    headers=headers,
    params=params
)

# Extract data
data = json.loads(response.content) The data is structured as follows: root
└── Puts/Calls
    └── Contract (by expiry date)
        └── Strike
            └── Fields (e.g. prices, greeks) We parse the JSON object using the following code to obtain a Pandas dataframe: # Extract puts data
puts = []
dates = list(data['putExpDateMap'].keys())

for date in dates:

    strikes = data['putExpDateMap'][date]

    for strike in strikes:
        puts += data['putExpDateMap'][date][strike]

# Define columns
columns = ['putCall', 'symbol', 'description', 'exchangeName', 'bid', 'ask',
    'last', 'mark', 'bidSize', 'askSize', 'bidAskSize', 'lastSize',
    'highPrice', 'lowPrice', 'openPrice', 'closePrice', 'totalVolume',
    'tradeDate', 'tradeTimeInLong', 'quoteTimeInLong', 'netChange',
    'volatility', 'delta', 'gamma', 'theta', 'vega', 'rho', 'openInterest',
    'timeValue', 'theoreticalOptionValue', 'theoreticalVolatility',
    'optionDeliverablesList', 'strikePrice', 'expirationDate',
    'daysToExpiration', 'expirationType', 'lastTradingDay', 'multiplier',
    'settlementType', 'deliverableNote', 'isIndexOption', 'percentChange',
    'markChange', 'markPercentChange', 'mini', 'inTheMoney', 'nonStandard']

# Convert to dataframe
puts = pd.DataFrame(puts, columns=columns) Transform The step will convert the data into the final structure/format to be loaded into Postgres. For our use case, it is fairly simple: (1) select the right columns and (2) ensure we have the right data types. transform First, inspecting the data, we identify several fields to keep (below). We will select only these fields for processing. Metadata: putCall, symbol, description, quoteTimeInLong (as unix timestamp) Contract info: openInterest, timeValue, theoreticalOptionalValue, strikePrice, expirationDate (as unix timestamp), daysToExpiration, volatility Trade data: bid, ask, last, bidSize, askSize, lastSize, highPrice, lowPrice, openPrice, closePrice, totalVolume Greeks: delta, gamma, theta, vega, rho Second, we ensure that the data is in the right format. Most of the columns have been parsed by Pandas correctly. Although we could assume that Pandas will continue to parse the data correctly, it may not be wise to do so. Suppose that for the first 6 months, the API has always returned 100% float values for the OHLC prices. One day, it starts to return the string , just like the options greeks data returned today. This results in Pandas now parsing the OHLC prices as types and the data loading step in the pipeline may fail. Hence, we should explicitly format the data. Also, for any data that was coerced to missing values, we fill that in with a placeholder value . nan object -99 The final step is to convert the column names into snake case. This is just a personal preference. The code to do everything we discussed is shown below: # Select columns
puts = puts[['putCall', 'symbol', 'description', 'bid', 'ask', 'last', 'bidSize',
    'askSize', 'lastSize', 'highPrice', 'lowPrice', 'openPrice',
    'closePrice', 'totalVolume', 'quoteTimeInLong', 'volatility', 'delta',
    'gamma', 'theta', 'vega', 'rho', 'openInterest', 'timeValue',
    'theoreticalOptionValue', 'strikePrice', 'expirationDate',
    'daysToExpiration']]

# Convert floats
def conv_num(x):
    return pd.to_numeric(x.astype(str).str.replace('NaN|nan', '', regex=True))

for col in ['bid', 'ask', 'last', 'highPrice', 'lowPrice', 'openPrice',
            'closePrice', 'volatility', 'delta', 'gamma', 'theta', 'vega',
            'rho', 'timeValue', 'theoreticalOptionalValue', 'strikePrice']:
    puts[col] = conv_num(puts[col])

# Specifically for puts delta: make it positive
puts['delta'] = -puts['delta']

# Convert strings
def conv_str(x):
    return x.astype(str)

for col in ['putCall', 'symbol', 'description']:
    puts[col] = conv_str(puts[col])

# Convert integers
def conv_int(x):
    return x.astype(int)

for col in ['bidSize', 'askSize', 'lastSize', 'totalVolume', 'quoteTimeInLong',
            'openInterest', 'expirationDate', 'daysToExpiration']:
    puts[col] = conv_int(puts[col])

# Fill missing values
puts = puts.fillna(-99)

# Rename columns
puts = puts.rename(columns={
    'putCall': 'put_call',
    'bidSize': 'bid_size',
    'askSize': 'ask_size',
    'lastSize': 'last_size',
    'highPrice': 'high_price',
    'lowPrice': 'low_price',
    'openPrice': 'open_price',
    'closePrice': 'close_price',
    'totalVolume': 'total_volume',
    'quoteTimeInLong': 'quote_time',
    'openInterest': 'open_interest',
    'timeValue': 'time_value',
    'theoreticalOptionValue': 'theoretical_value',
    'strikePrice': 'strike_price',
    'expirationDate': 'expiration_date',
    'daysToExpiration': 'dte',
}) Load After extracting the data and transforming it to conform to the defined schema, we will need to load the data into our Postgres database. We use , keeping only the first entry in the event of repeated rows: INSERT ... ON CONFLICT DO NOTHING INSERT INTO FB (<all columns here>) VALUES (<all values here>) ON CONFLICT DO NOTHING; We use the library to load the data from Python into Postgres. We follow the typical process of (1) defining the query (as above), (2) connecting to the database, (3) creating a cursor, (4) executing the query with the parameters, (5) committing the transaction, and then (6) closing the connection. Note that we have placed the database password into the file to avoid hardcoding it. psycopg2 .env import psycopg2 as pg2

col_str = ', '.join(puts.columns.tolist())
query_insert = f"INSERT INTO fb ({col_str}) VALUES %s ON CONFLICT DO NOTHING"

# Connect to database
conn = pg2.connect(
    host='localhost',
    database='optionsdata',
    user='postgres',
    password=env['DB_PASSWORD']
)

# Loop through rows
with conn.cursor() as cursor:
    for t in puts.itertuples(index=False, name=None):
        cursor.execute(query_insert % str(t))
    conn.commit()

# Close connection
conn.close() To inspect the data, we retrieve all records from the table using the following code: # Run select * query
with conn.cursor() as cursor:
    cursor.execute('SELECT * FROM fb;')
    df = pd.DataFrame(cur.fetchall(), columns=...) The first time we run both snippets above, we'll obtain a dataframe ( ) containing data from the latest API query. If we run it again without changing the API data, we should see no change to . df df Summary In this post, we achieved the following: Developed code to retrieve data from the TD Ameritrade Option Chains API Developed code to process the data Developed code to load the data from Python into the PostgreSQL table Checked that the loading worked as intended Putting everything together, we have a one-off script that enables us to extract data from an API, transform it, and load it into a Postgres database. This is similar in functionality to the solutions by [2], [3], and [4], which have data persisted in a database or file as opposed to a Pandas dataframe, putting them one level above the other solutions. Still, this is only a snapshot. We need to run this code repeatedly at different times of the day, and a tool to manage these runs.

If you Google terms like “ ” or “ ” you should be able to find more examples. This project uses JavaScript to allow designers to create such designs in the browser which anyone can download and fabricate. parametric furniture cnc furniture It is a new way to think about furniture design and experiment with new ideas. We are just as curious to see what can be done. Furniture designs currently have a high entry barrier due to the resources required to manufacture at scale. A designer needs to establish a studio/fabrication infrastructure or align with larger companies to try to bring his/her designs to the market.With our production process, we can enable more upstarts to present their designs and let the community decide. A community curated design collection. The designs are exported as Computer Aided Design (CAD) files by the web app, which can be used for fabrication wherever needed using high precision machines. Sending a chair can mean just emailing the design file to any location. Sending chairs across geographies is like emailing a file. We promote an open licensing system to allow all designs to be replicated and forked by anyone. A design can be copied and morphed in different ways by different people adapting the design for their use. It’s like a natural selection process for designs. A framework for evolving designs. All aspects of the design are open and recorded publicly as the design develops. The designs stay ‘honest’ in concept as the narrative is recorded at every step. The exact contributions of different collaborators is recorded in the process. Public development records log the design narrative as decisions are made. The design, manufacture and supply chain has been a closed loop system owned entirely by individual entities.By breaking apart these aspects we think we can involve more independent participants to contribute and gain from this process while still keeping the whole process sustainable. Wider community participation in the design and production process. Current Stage This is at a proof-of-concept stage. I am excited about the possibilities and exploring who else finds this cool.

If Wall Street can’t beat this volatile market, what makes you think you can?

Wouldn’t it better if you just hedl? I personally have made much more money in hodling than trading, with half the stress. blockchain technology Below is an example of why hodling would be a better option in this bullish and volatile market. Here is an outline from a social media post that was edited with today’s price (January 2, 2018). “If you took 5 of the cryptocurrencies that are still in the top 10 from Jan. 1, 2017 and compare them to Jan. 2, 2018 here is what you would have if you invested $1,000 in each on Jan 1st 2017… BTC — $963.00 to $16,460 — total $17,092ETH — $8.26 to $878— total $106,295XRP — $0.0065 to $2.41— total $370,769LTC — $4.37 to $255 — total $58,352DASH — $11.26 to $1,160 — total $103,019 …for a grand total of $655,527 for $5,000 invested.” I really have a hard time believing that someone can do better than this in trading without having a $1 million initial capital. Trading is just like any other profession that requires years of training. If you pretend to be one, you will get rekt. Tuur Demeester Who should hodl? You should hodl: If you are a believer of this blockchain technology. If you have patience. If you believe that the peak of this bubble is not even priced in yet. If you believe that we will match or possibly surpass the Internet bubble’s $3 trillion market capital. If you can afford to lose and risk it all. If you don’t need the money at this time. If you do not have the slightest idea of what you’re doing. If you don’t have the time to keep up with how fast this space is moving. Anthony Pompliano Long-term versus short-term.

Here’s how I do it. I just traded the last few of my bitcoins for $ETH, which I’ve bought for around $100 and held since 2013. I was able to hodl due to my positive attitude view towards blockchain technology. When I first heard about bitcoins, I thought of decentralized paypal. I instantly fell in love with the idea of not having anyone freeze my account when I sell things online due to charge backs and fraud claims from the other party. Then Ethereum came and it just strengthened my opinion about this technology. Today, I am still hodling some $ETH from which I’ve purchased from the initial coin offering and some I have diversified into other ICO projects that I personally believed in (check my “ ”). Due Diligence Checklist for Investing in Cryptocurrency My faith and wanting to be part this of revolution is what makes me want to hodl onto my investment longer. I want to see what Bitcoin, Ethereum and other potential disruptive dApps develop and grow 5 years from now. I want to see what life would be like with a matured blockchain ecosystem. Other than the financial motive that comes with investing in blockchain long term, I want to see the impact it will have on our daily lives. Michael Goldstein “But..but…” hodl that thought, because I have more things to say. Hodling does not require experience or skills, traders do. Stick to what you know, you’re not a trader, you will get rekt. Ask yourself what this coin/token is going to be worth 5 yrs from now, not what’s it going to be worth next week or next month. It will give you new perspective about the future of bitcoin and other cryptocurrencies. Hodling to me is something more than just a chant to encourage people to not panic and sell during the bear market. Hodling is a strategy that I have used for the last few years and has continued to benefit me more than trading (I am not a trader, my background is medicine, not finance). We are at the mania phase right now of this market. Maybe in a few days or a couple weeks, this bullish market will experience fatigue and the hype will not be enough to sustain it. What do you do? Do you panic and sell? What if it goes up? Do you trade for a loss? If not, and it keeps going up, do you buy back at the top? How about just letting your investment grow by hodling? “Are you here for the long haul? or for the next 6 months?” — Jimmy Song Did you come here to trade? or did you come here to invest your money in the growth of this blockchain technology?
