Hey Hackers, We're proud to introduce Algomo - an platform with the goal of revolutionising customer service! We are building an AI platform that helps companies of any size fully automate their customer service in 100+ languages, easily and affordably. AI Our chatbots are capable of sourcing data from various inputs like URLs, PDFs and Notion pages and in under 5 minutes are able to answer any question a customer has! We’ve been nominated for HackerNoon and this is our interview. Startups of the Year Vote for us today! https://hackernoon.com/startups/europe/europe-london-england-uk My Role My name is Charis Sfyrakis, I hold a Masters degree in Artificial Intelligence from the University of Edinburgh and I am an alumnus of Entrepreneur First, HSBC (where I built their global chatbot framework), Barclays & BNP Paribas. I am the CEO here at Algomo where I focus on leading the Algomo team; from helping our business development team reach as many people as possible to reviewing our tech team’s progress, I spend my days elevating and inspiring my employees whilst making sure that we are on track to achieve our goals and bring our vision to life! How We're Disrupting/Improving the Customer Service/Chabot Industry These days, customers have high expectations when it comes to customer service. One poor experience can wipe away any loyalty, with over $75 billion in revenue being lost by companies as a result of bad customer service and 9/10 customers saying that they have switched to a competitor following a bad customer experience. Similarly, despite $1.3tn being spent on customer service calls every year, 91% of customers prefer self help tools over calling a help centre and 9/10 customers say quick responses to inquiries are important when deciding what company to buy from. Chatbots are usually used solely for simple queries, and thus fail to consider the rest of the customer journey - resulting in low market penetration, lost customers and low CSAT scores for firms. In addition, 7/10 customers prefer companies that support their native language whilst just 28% of users receive support in their language, and 87% of consumers who don’t understand English won’t even consider buying from an English website.  For other monolingual AI tools, every language requires building a separate AI, making it expensive and resource-intensive. Training a bot takes ages, as one needs to provide a lot of training data across multiple languages. And that’s where we come in. We are utilising the cutting-edge technology of generative AI to build the ultimate customer service platform. We pride ourselves on the efficacy and simplicity of our chatbots - enabling 45% of customer support interactions to be resolved through automation with a 92% model accuracy, all of which can be set up in under 5 minutes, in over 100 languages. Standing Out from The Crowd At Algomo, we know that being successful in a market as hot as AI customer service will require being the best at what we do and allowing our product to speak for itself. We’re initially targeting companies in low-resource languages - which is an untapped market - and we have bundled 3 traditionally separate products (AI, localisation and LiveChat) to create a truly unique product, which outperforms competitors in multilingual capabilities and ease of setup. Our platform offers AI and live chat in 109 languages without the need for translations and seamless transition between all languages within the same chat. Also, our customers can build a bot using just a URL and integrate all internal documents with a click of a button. We also top the charts in terms of fitting into the existing set-up of our customers, as our platform enables them to connect to existing tools such as Notion, Hubspot and Slack and reply to customer queries from email or Slack. Our product is also optimised for SMEs (not just corporates, as compared to other providers), so our increased accessibility sets us apart even more. We know that putting customers first is crucial when building a startup, and we believe that our product is suited to their needs better than everyone else. Our Predictions/Thoughts on the Customer Service Industry in 2023 ChatGPT has changed the world, expanding our beliefs about what technology is possible of doing. After Open AI’s brainchild reached 100 million monthly active users in 2 months, it has officially been declared the fastest-growing app in internet history. For a number of years, many firms have already been using AI to resolve millions of customer inquiries. But now ChatGPT’s powerful communication skills are being combined with the ability to integrate into commercial systems like internal knowledge bases and CRMs, with firms seeing customer requests being resolved end to end at the same level as human agents. The customer service industry is currently facing the lowest satisfaction ratings in decades due to a shortage of agents and growing demand, so the use of LLMs will be a major topic for companies trying to earn back customer loyalty in 2023. Over the last few years, contact centres have increasingly utilised AI to deal with common requests such as billing and account management, and this trend will extend into 2023. This has helped to diminish wait times and free agents to spend more time on revenue-generating issues, with cost saving estimates of more than $80 billion by 2026. Despite the immense benefits of leveraging LLMs in a firm’s customer service strategy, they do not come without risks. The main one is hallucinations, where an answer is given that is not actually accurate. As companies see customer support as a chance to repair any damage to its reputation in the eyes of a customer, giving them an incorrect answer to a query is the last thing the company wants. That is why at Algomo we will be constantly working throughout 2023 to limit these occurrences in our chatbots, to ensure that the huge advantages of this new technology can be harnessed by all firms without apprehension. What word defines the state of the Customer Service Industry in 2023? The word that we would use to define the state of the customer service chatbot industry is transforming. Facing consumers who are increasingly seeking instant gratification, with TikTok counting approximately 1.7 billion users worldwide in 2022 (up by over 66 percent compared to 2020), and with increasing digital penetration in developing economies with previously underserved languages - as the next billion internet users will primarily come from economically fast-growing emerging and developing nations - it is essential that customer service keeps up. These shifts in customer personas must be catered to if firms want to attract and retain customers to keep their businesses thriving. Thus, the move towards the automation of customer inquiries leveraging AI technology is becoming more and more essential, granting adopting firms a competitive advantage over those who do not.  Furthermore, multilingual capabilities are becoming necessary if a firm wants to grow and cater to the wide array of increasingly digitally savvy consumers from around the world. In these times of great change, at Algomo we have spent countless hours evolving our product to position ourselves to help companies best cater to the modern consumer. We would love to get your support to help us do more! Why we decided to participate in HackerNoon's Startup of the Year awards We wanted to take part in HackerNoon’s Startup of the Year awards this year as we wanted to show the world the progress that we have been making. So far, we have created a full-fledged solution and launched a beta version of our product - and it works! We have gained 25 customers and 100 Monthly Active Users (MAUs) since our launch in June 2023, and we are just getting started! We hope to develop our tool-calling capabilities, such as with Shopify, and extend the presence of AI in more of the customer interaction process. It is an exhilarating time here at Algomo as we are going from strength to strength, improving our product to better serve our customers every day, and we hope that you are as excited as we are! Final Thoughts Having received grants from Innovate UK, Algomo is clearly being recognised for its importance in progressing the use of AI to the wider economy. Using cutting-edge technology and with an outstanding team, we are confident in our ability to make the interaction between companies and customers as smooth and efficient as possible. We hope that you can help us on our mission! Vote for us today! https://hackernoon.com/startups/europe/europe-london-england-uk

THE RESULTS OF CRIMINAL ANTHROPOLOGY

On a scale from 1 to 10 how good are your data warehousing skills? Want to go above 7/10? This article is for you then. How good is your SQL? Want to get ready for a job interview asap? This blog post explains the most intricate data warehouse SQL techniques in detail. I will use BigQuery standard SQL dialect to scribble down a few thoughts on this topic. 1. Incremental tables and MERGE Updating table is important. It is important indeed. Ideal situation is when you have transactions that are a PRIMARY key, unique integers and auto increment. Table update in this case is simple: https://gist.github.com/mshakhomirov/18775cbbe8288af864ad79247c0de63d?embedable=true#file-1-1-sql That is not always the case when working with denormalized star-schema datasets in modern data warehouses. you might be tasked to create with SQL and/or incrementally update datasets with just a portion of data. might not exist but instead you will have to deal with data model where unique key depends on the latest (or timestamp) known. For example, in dataset depends on the latest known connection timestamp. In this case you would want to existing users and the new ones. sessions transaction_id transaction_id user_id last_online update insert MERGE and incremental updates You can use or you can split the operation into two actions. One to update existing records with new ones and one to insert completely new ones that don't exits (LEFT JOIN situation). MERGE is a statement that is generally used in relational databases. Google BigQuery MERGE Command is one of the Data Manipulation Language (DML) statements. It is often used to perform three main functions atomically in one single statement. These functions are UPDATE, INSERT, and DELETE. MERGE UPDATE or DELETE clause can be used when two or more data match. INSERT clause can be used when two or more data are different and do not match. The UPDATE or DELETE clause can also be used when the given data does not match the source. This means that the Google BigQuery MERGE Command enables you to merge Google BigQuery data by updating, inserting, and deleting data from your Google BigQuery tables. Consider this SQL: https://gist.github.com/mshakhomirov/5ad1a7518c54bc030d1c78b56fe3cf82?embedable=true#file-1-2-sql 2. Counting words Doing UNNEST() and check if the word you need is in the list you need migth be useful in many situation, i.e. data warehouse sentiment analysis: https://gist.github.com/mshakhomirov/694e040539b0d1b556f8e053d315a3bf?embedable=true#file-2-sql 3. Using IF() statement outside of the SELECT statement This gives us an opportunity to save some lines of code and be more eloquent code-wise. Normally you would want to put this into a sub-query, and add a filter in the clause but you can do instead: where this https://gist.github.com/mshakhomirov/933e6a358e49dcccd4e547a5509c8fda?embedable=true#file-3-sql Another example how to use it with tables. . This is bad example because since the matching table suffixes are probably determined dynamically (based on something in your table) you NOT partitioned Don't do this will be charged for a full table scan. https://gist.github.com/mshakhomirov/1c62d79cd9690140c569cd047b9d491f?embedable=true#file-3-2-sql You can also use it in clause and functions. HAVING AGGREGATE 4. Using GROUP BY ROLLUP The ROLLUP function is used to perform aggregation at multiple levels. This is useful when you have to work with dimension graphs. The following query returns the total credit spend per day by the transaction type (is_gift) specified in the clause, and it also shows the total spend for each day and the total spend in all the dates available. where https://gist.github.com/mshakhomirov/4cf738aaad967fe92c4fb7192874fadf?embedable=true#file-4-sql 5. Convert table to JSON Imagine you are required to convert your table into JSON object where each record is an element of nested array. This is where function becomes useful: to_json_string() https://gist.github.com/mshakhomirov/aac1f93312ae305ba80c915fe4a2a386?embedable=true#file-5-sql Then you can use it anywhere: dates, marketing funnels, indices, histogram graphs, etc. 6. Using PARTITION BY Given , and columns. For EACH date, how do you show the total revenue value for EACH customer while keeping all the rows? You can achieve this like so: user_id date total_cost https://gist.github.com/mshakhomirov/e4f11721eb5a3182150df08f25b70d64?embedable=true#file-6-sql 7. Moving average Very often BI developers are tasked to add a moving average to their reports and fantastic dashboards. This might be 7, 14, 30 day/month or even year MA line graph. So how do we do it? https://gist.github.com/mshakhomirov/ebf5488d0036bc9b84ae05889346d986?embedable=true#file-7-sql 8. Date arrays Becomes really handy when you work with or want to check some dataset for missing values, i.e. dates. BigQuery has a function called : user retention GENERATE_DATE_ARRAY https://gist.github.com/mshakhomirov/2ba5a67053f85794462dab98e56ad74d?embedable=true#file-8-sql 9. Row_number() This is useful to get something latest from your data, i.e. latest updated record, etc. or even to remove duplicates: https://gist.github.com/mshakhomirov/05d0c04c5975207d98552ffd436add8b?embedable=true#file-9-sql 10. NTILE() Another numbering function. Really useful to monitor things like if you have a mobile app. For example, I have my App connected to Firebase and when users I can see how long it took for them. Login duration in seconds login This function divides the rows into buckets based on row ordering and returns the 1-based bucket number that is assigned to each row. The number of rows in the buckets can differ by at most 1. The remainder values (the remainder of number of rows divided by buckets) are distributed one for each bucket, starting with bucket 1. If evaluates to NULL, 0 or negative, an error is provided. constant_integer_expression constant_integer_expression https://gist.github.com/mshakhomirov/16fe941aa8c4ed79e4aad8b7049b307a?embedable=true#file-10-sql 11. Rank / dense_rank They are also called functions. I tend to use as it doesn't skip the next available ranking whereas would. It returns consecutive rank values. You can use it with a partition which divides the results into distinct buckets. Rows in each partition receive the same ranks if they have the same values. numbering DENSE_RANK as default ranking function RANK Example: https://gist.github.com/mshakhomirov/459b68c5f3d1e8284c01e516db1d8dcb?embedable=true#file-11-1-sql Another example with product prices: https://gist.github.com/mshakhomirov/4c90a6fc8516d8264e172676a83a1048?embedable=true#file-11-2-sql 12. Pivot / unpivot Pivot changes rows to columns. It's all it does. Unpivot does the . opposite https://gist.github.com/mshakhomirov/f90b035ba259e672d4d51a669e0cd1fc?embedable=true#file-12-sql 13. First_value / last_value That's another useful function which helps to get a delta for each row against the first / last value in that particular partition. https://gist.github.com/mshakhomirov/ea4de9144b97bf8c196cab07609c309e?embedable=true#file-13-sql 14. Convert a table into Array of structs and pass them to UDF This is useful when you need to apply a user defined function (UDF) with some complex logic to each row or a table. You can always consider your table as an array of TYPE STRUCT objects and then pass each one of them to UDF. It depends on your logic. For example, I use it to calculate purchase expire times: https://gist.github.com/mshakhomirov/35d956fa9db86b12b44ab62c00f42a40?embedable=true#file-14-sql In a similar way you can create tables with no need to use . For example, I use it to mock some test data for unit tests. This way you can do it very fast just by using + + in your editor. UNION ALL Alt Shift Down https://gist.github.com/mshakhomirov/6ea226c1b5b789d4a31691ce065c20d7?embedable=true#file-14-2-sql 15. Creating event funnels using FOLLOWING AND UNBOUNDED FOLLOWING Good example might be marketing funnels. Your dataset might contain continiously repeating events of the same type but ideally you would want to chain each event with next one of a different type. This might be useful when you need to get a list of something, i.e. events, purchases, etc. in order to build a funnels dataset. Working with PARTITION BY it gives you the opportunity to group all the follwoing events no matter how many of them exists ineach partition. https://gist.github.com/mshakhomirov/05fd7d79d8acf3b173181a5d950ab6e7?embedable=true#file-15-sql 16. Regexp You would to use it if you need to extract something from unstructured data, i.e. fx rates, custom groupings, etc. Working with currency exchange rates using regexp Consider this example with exchange rates data: https://gist.github.com/mshakhomirov/9ca6e153da19c491034bd57995875308?embedable=true#file-16-1-sql Working with App versions using regexp Sometimes you might want to use to get , or versions for your app and a create a custom report: regexp major release mod https://gist.github.com/mshakhomirov/b1f442a296ffef52c7baa1245e1dc316?embedable=true#file-16-2-sql Conclusion SQL is a powerful tool that helps to manipulate data. Hopefuly these SQL use cases from digital marketing will be useful for you. It's a handy skill indeed and can help you with many projects. These SQL snippets made my life a lot easier and I use at work alomost every day. More, SQL and modern data warehouses are essentials tools for data science. Its robust dialect features allow to model and visualize data with ease. Because SQL is the language that data warehouses and business intelligence professionals use, it's an excellent selection if you want to share data with them. It is the most common way to communicate with almost every data warehouse / lake solution in the market.

What piece of technology or app do you use in your daily life or remote work life that isn’t so common, but you think others could benefit from using? In this Slogging thread, the HN team dives into the apps and tools we use on a daily basis. This thread by Limarc, Amy Shah, Sidra Zafar, Adrian Morales, Blake Cram, Tirtha, Gimbiya Galadima, Jessica, Iggy and Davis David occurred in hackernoon's official #fellowship-central channel, and has been edited for readability. Slogging Limarc Sep 8, 2021, 5:56 AM What piece of technology do you use in your daily life or remote work life that isn’t so common, but you think others could benefit from using? Limarc Sep 8, 2021, 5:57 AM For me, it is without a doubt, (virtual assistants in general). When I first started working remotely I used Alexa to: Amazon Alexa Create daily task lists Create weekly task lists Set meeting reminders Set task timers Remind me to exercise and move around every hour during my workday Play Skyrim while folding laundry. I still use it for reminders and alarms everyday. I am weary of the invasion of privacy aspect…but I’ve also kinda accepted it. Limarc Sep 8, 2021, 6:00 AM Also I have to say, the might have saved my health throughout this pandemic. I couldn’t go to the gym, and I was too lazy to go jogging, so instead I played games like Beat Saber and Thrill of the Fight to stay in shape in my tiny Tokyo apartment. VR has been a lifesaver and helped keep me sane throughout all the crap we’ve been through in the past 2 years. I even wrote an article about VR fitness games back in the days of my freelance video game writing career: Oculus Quest https://www.keengamer.com/articles/features/opinion-pieces/5-best-vr-fitness-games-on-the-oculus-quest/ Amy Shah Sep 8, 2021, 8:14 AM I used the app ( ) for over 600 days during the Pandemic. It's free and anyone can use it, but there is a premium version available without ads. I learned German primarily. Daily I would just do one lesson for about 5 minutes. That was the extent of my commitment! Recently, someone I know took an introductory college level German class at a university, and I knew enough to help them with their homework because of Duolingo! Duolingo http://duolingo.com Amy Shah Sep 8, 2021, 8:14 AM A lesser known language website is ( ). The company takes existing Youtube videos in other languages and adds a feature to allow you to play them back slowly or loop the videos with subtitles so you can pick up the nuances in languages. There are also games on the website to test your listening and reading comprehension. While the Yabla is not as addictive as Duolingo, it has made learning cultural aspects of a language easier. Yabla offers education in English, Spanish, French, Italian, Portuguese, and German.

Previously, I used PowerPoint and paint to draw the biological illustrations which did not come out nicely. So, I came across this ( ) which has lots of pre-defined biological icons like cells, tissues, bacteria etc. This app has electrified my figures game. It comes with free version and a premium version which is paid. biorender app https://biorender.com/ Sidra Zafar Sep 8, 2021, 12:00 PM Also when you are a PhD student your mental health suffers a lot. Most often students find them selves drenched in ocean of scattered thoughts and all you need is to quite your mind. To cater this I have been using a meditation app called ( ).

The best app for day planning that I have found has to be You can plan a whole day, sync your calendars and get notifications when it is time to move on to the next part of your day.

Structured. https://apps.apple.com/us/app/structured-day-planner/id1499198946 Blake Cram Sep 9, 2021, 6:16 PM I love being active. At the start of COVID-19's outbreak and as quarantines and stay-in-place orders were issued, I had to be more creative to stay active as places like my rock climbing gym were no longer available. After weeks of scouring the internet for online workouts and yoga classes, I stumbled upon --an app with a wealth of yoga, HIIT workouts, stretching and meditation practices that I can use on my phone or on my laptop. I felt like yoga classes through video were especially hit or miss in quality until I stumbled upon Alo. The instructors communicate movements efficiently and clearly, while the video quality is professionally executed, so it is easy to follow along. The UI on the site is especially approachable in navigating their HUGE library of classes with a large range of class durations and difficulties. I can find what I need to cater to what I need in a given day. I use this app every day and it helps me get take care of my physical and mental health even while stuck at home. https://www.alomoves.com Blake Cram Sep 9, 2021, 6:32 PM Another piece of technology I've been enamored with is the . I used to have a big-brand smartwatch (I won't name any names), and I was really disappointed with the lack of detail in workouts, the laughably short battery life, and pestering reminder of emails, texts and phone calls--that I went to my phone to respond to anyway. I sold my smartwatch, parted with its hefty and absolutely unused cellular plan, and arrived at the Coros. This watch gives me ridiculously detailed running data that I can nerd out over. The watch tracks my running patterns, heart rate, predicts race times, tracks recovery and training efficiency. The battery (no exaggeration) lasts almost two weeks without charging even while running around 30 miles a week. And, I still get basic texts and email notifications if I want them, so I can keep track of things I need to when I'm working.  I got way more of an insight to my health without the headaches. https://coros.com/apex.php Limarc Sep 10, 2021, 3:08 AM Very cool ideas everyone I've already checked them out. I also got a new keyboard and it's official, a mechanical keyboard makes you sound like you type faster than you actually do.

Tirtha Sep 14, 2021, 6:11 AM I love making doodles and think with illustrations. If ever I need to plan - whether a software implementation, party planning or just random thought orientation, I use a simple webtool. Also on my ipad, there's an app called sketches( ) I've been using it for making anime n other art, but also to just draw random scribbles and patterns to explain an idea. http://draw.io Tayasui https://apps.apple.com/in/app/tayasui-sketches/id641900855 🙏 1 Limarc Sep 14, 2021, 6:57 AM Tirtha that's awesome. Is it pretty seamless to save your creations to device or email them to yourself, post them on Instagram and things like that? Tirtha Sep 14, 2021, 7:12 AM Yup. In Tayasui, you can do icloud sync, have local storage backup and pretty easy to share via email n other apps. I take backups after a piece is complete and later schedule uploads on Instagram. also allows you to save your work on Google drive, Github, Gitlab & of course, local storage. http://Draw.io Limarc Sep 14, 2021, 8:08 AM What do you all think about this tool? You think it'd help remote teams feel more "connected" ? https://www.remotion.com/ Tirtha Sep 14, 2021, 3:51 PM Interesting one Limarc the team members get to have a balanced engagement with colleagues.

Gimbiya Galadima Sep 16, 2021, 8:01 AM I like the concept of Gathertown. It states that I can register for free: a 30-day free registration sounds amazing. So I'll register and see the amazing features it offers. 💚 1 Jessica Sep 16, 2021, 2:22 PM I like using Microsoft for my daily to-do list and to take notes (love the color coding tabs). OneNote 💚 1 Iggy Sep 17, 2021, 5:53 AM I like using , it's so cool and they are easy to use , no charges, I think you should try it out if you are a software engineer, lastly clickup is also one of the best project management software I've used too, you try that out.. Basecamp 🙏 1 Limarc Sep 17, 2021, 6:00 AM Iggy do you have an opinion on Basecamp versus Trello or Notion? Iggy Sep 17, 2021, 6:14 AM Well, what I will say about basecamp is that it took some features from Notion, e.g real-time documentation, file upload, etc then adding on top of it is the real-time group chat feature, meaning you can communicate with the team all in the same app, in my own opinion this helps to keep the team together without having a different platform for chatting. Trello is good for productivity and I guess they are all solving different problems but just some difference . Davis David Sep 17, 2021, 2:12 PM I use to write down some article ideas I want to write or sometimes I  save the link of an article I have read on my mobile phone or my laptop that I want to read more, explore and see if I can write new thing related to the article I read.

25 SEO Mistakes That Will Hurt Your Website Rankings in 2020

Automating My Manual Scalping Trading Strategy One of the advantages of running automatic trading strategies is that you can quickly and consistently act on price action. Even if you have enough time to trade the same idea manually, you need to watch the market movement very closely and keep paying attention to multiple monitors. With algorithmic trading, you can automate this on . Alpaca Also, please keep in mind that this is only an example to help get you started. Consider testing a strategy in paper trading to see if and how it works before trying it in a live brokerage account. If you'd prefer to "fast forward" to full code, go ! directly to the GitHub repository What is Scalping Strategy? There are many types of trading strategies, but this one is called . “scalping” strategy Scalping attempts to take smaller profits quicker, which can add up, without risking your assets holding for long. It requires a strict exit strategy, though, because one large loss could eliminate the many small gains. The above-referenced article explains the strategy in more detail, as well as the different types of scalping. Many day traders are applying this idea, but in order to do this manually, a lot of energy and attention is required in order to keep monitoring the large amounts of information on the screen. Why Scalping Strategy for Algorithmic Trading? When looking back at the intraday chart at the end of the day, it is possible to see different missed opportunities. However, it's not always possible to act during market hours. There could also be even more opportunities if it were possible to monitor a dozen stocks independently versus just looking at one stock. For example, when looking at a TradingView chart for SPY with 20 minute simple moving average on 10/04/19 (below), it's possible to see price crossover where it would have been possible to have taken a small profit if the position had been timely. With the scalping strategy, the goal isn't for a large profit margin, rather, aim for a small upward price movement while it’s going up. It's usually too hard to monitor even a few charts at the same time manually, so that's where algorithms come in. Automate This! Python’s asyncio to Manage Algo Flow What if I can have many of me watching each stock. I started coding based on the idea and found Python’s asyncio is pretty useful to manage algorithm flow for multiple stocks, each of which I found to be pretty simple. Check out Python's Asyncio here! Starting with a Single Stock To begin with a single stock, I wrote a class that manages simple state and event handler for a single stock using (simplified below). Alpaca API self._symbol = symbol
     self._bars = []
     self._state = self._bars =  self._bars.append(bar) self._state == : self._check_signal():
         self._submit_buy()
         self._state = event == : self._state == :
         self._submit_sell( self._get_last_price() + )
         self._state = self._state == :
         self._state = : class ScalpAlgo : def __init__ (self, symbol) 'TO_BUY' : def on_bar (self, bar) '''called when new bar arrives''' if 'TO_BUY' if 'BUY_SUBMITTED' : def on_order_event (self, event) '''called if order status changes''' if 'fill' if 'BUY_SUBMITTED' 0.01 'SELL_SUBMITTED' elif 'SELL_SUBMITTED' 'TO_BUY' The main flow is pretty simple as you can see. It is basically a state machine with 4 distinct states, and given the new event (signal can be triggers, order fills, etc.), the state transitions to look for the next action. In the , I am calculating 20-minute simple moving average and compare with the price. _check_signal() function mavg =  self._bars.rolling( ).mean().close.values
    closes =  self._bars.close.values closes[ ] < mavg[ ] closes[ ] > mavg[ ]: : : def _calc_buy_signal (self) 20 if -2 -2 and -1 -1 return True else return False Subscribing Websockets Since it is important to take action as quickly as the signal triggers, we subscribe to the real-time bar updates from Polygon websockets as well as Alpaca’s order event websockets. Everything is event-driven. stream = alpaca.StreamConn()
  algo = ScalpAlgo( )  @stream.on( ) algo.on_bar(data)  @stream.on( ) algo.on_order_event(data.event)
  stream.run([ , ]) : def main () 'SPY' 'AM.SPY' async : def on_bar (conn, channel, data) 'trade_updates' async : def on_order_event (conn, channel, data) 'AM.SPY' 'trade_updates' This run() function runs in definitely until the program stops. All events are dispatched to the event handlers in Python’s asyncio loop, driven by the new messages from websockets. Focus on the State Transitions Once the structure is built, all you need to do is to focus on the state transitions in a couple of different cases. Beyond the simplified sample code above, you may want to handle cancel/rejection event for your buy order. If you want to forget about it since you don’t have the position, but want to get in next time the same signal triggers, then you will set the state to TO_BUY so you can reset the state. You may also want to consider setting those orders to cancel orders if they don’t fill within the reasonable timeframe after submission. Or those working orders may be canceled from dashboard. Now, the question is how to scale this to dozens of stocks? It’s important to keep the signal as strict as possible so that you don’t get into a position under an unintended situation to buy. The more you tighten the signal rule, the less entry opportunities you have. However, you should have more opportunities if you run this against dozens of stocks. Concurrent algorithm Scaling This to Multiple Stocks To scale this idea to many stocks you want to watch, there is actually not much more to do. The ScalpAlgo already takes the stock symbol as parameter, and manages state for this symbol only, which means you just need to create more of this class instance with different symbols. As an example: stream = alpaca.StreamConn()
  fleet = {}
  symbols = ( , , ) symbol symbols:
    fleet[symbol] = ScalpAlgo(symbol)  @stream.on( ) data.symbol fleet:
       fleet[data.symbl].on_bar(data)  @stream.on( ) order = data.order order[ ]:
      fleet[order[ ]).on_order_event(data.event)  stream.run([ + symbol symbols] + [ ]) : def main () 'SPY' 'QQQ' 'DIA' for in 'AM.*' async : def on_bar (conn, channel, data) if in 'trade_updates' async : def on_order_event (conn, channel, data) if 'symbol' 'symbol' 'AM.' for 'trade_updates' The fleet holds each algorithm instance in a dictionary using symbol as the key.
