Photo by on Adrian Curiel Unsplash In the last 5–10 years algorithmic trading, or , has gained popularity with the individual investor. The rise in popularity has been accompanied by a proliferation of tools and services, to both test and trade with algorithms. I’ve put together a list of 9 tools you should consider using for your algo trading process. algo trading Web Services: The following are managed-services that you can use through web browsers, and don’t require much setup from the user. As someone who’s recently started in this field, I found it easy for new algo traders to try out. (1) : Quantopian A Boston-based crowd-sourced hedge fund, Quantopian provides an online IDE to backtest algorithms. Their platform is built with python, and all algorithms are implemented in Python. When testing algorithms, users have the option of a quick backtest, or a larger full backtest, and are provided the visual of portfolio performance. Live-trading was discontinued in September 2017, but still provide a large range of historical data. They also have a serious community of developers, and post an ongoing DAILY contest with 10 winners awarded each day for a total of $5000 per month in prize money (*updated from the previously written as “periodically hold contests”). Quantopian provides capital to the winning algorithm. _Algorithm writers win thousands of dollars each month in this quant finance contest. Quantopian provides the education…_www.quantopian.com Quantopian Contest (2) : QuantConnect QuantConnect, is another platform that provides an IDE to both backtest and live-trade algorithmically. Their platform was built using C#, and users have the options to test algorithms in multiple languages, including both C# and Python. QuantConnect also embraces a great community from all over the world, and provides access to equities, futures, forex and . They offer live-trading integration with various names such as InteractiveBrokers, OANDA, and GDAX. crypto trading (3) QuantRocket: QuantRocket is a platform that offers both backtesting and live trading with InteractiveBrokers, with live trading capabilities on forex as well as US equities. It’s specifically designed for trading with InteractiveBrokers, and sets itself apart with its flexibility. QuantRocket supports multiple engines — its own Moonshot, as well as third party engines chosen by the user. While QuantRocket doesn’t have a traditional IDE, it is integrated well with Jupyter to produce something similar. One thing to keep in mind is that QuantRocket . Pricing plans start at 19.99/month USD, with annual options. is not free Local Backtesting/LiveTrading Engines: In today’s software world, you have lots more freedom if you make some effort outside of those managed-services. If you are comfortable this way, I recommend backtesting locally with these tools: (4) : Zipline/Zipline-Live _zipline - Zipline, a Pythonic Algorithmic Trading Library_github.com quantopian/zipline Quantopian’s IDE is built on the back of Zipline, an open source backtesting engine for trading algorithms. Zipline runs locally, and can be configured to run in virtual environments and Docker containers as well. Zipline comes with all of Quantopian’s functions, but not all of its data. To balance that, users can write custom data to backtest on. Zipline also provides raw data from backtests, allowing for versatile uses of visualization. Zipline discontinued live trading in 2017, but there is an open source project that works with Interactive Brokers. It has many of the same features Zipline does, and provides live trading. Zipline-live (5) : BackTrader _from datetime import datetime import backtrader as bt class SmaCross(bt.SignalStrategy): params = (('pfast', 10)…_www.backtrader.com backtrader - Backtesting / Trading Backtrader is currently one of the most popular backtesting engines available. It was built using python, and has a clean, simple, and efficient interface that runs locally (no Web Interface). One thing to keep in mind, backtrader doesn’t come with any data, but you can hook up your own market data in csv and other formats pretty easily. Starting with release 1.5.0, BackTrader has live-trading capabilities. It’s been a popular choice with algo traders, especially after Zipline discontinued live trading. (6) : IBPy _IbPy - Python API for the Interactive Brokers on-line trading system._github.com blampe/IbPy IBPy is an unaffiliated third party python wrapper for InteractiveBroker’s Trade Workstation API. Before IB started providing their official API library for python, this was the only way to connect to TWS for algorithms written in python. IB has released an official python SDK, and this library is heading towards begin obsolete(while still being relevant for python2 users). But there still remain a significant number of live trading engines/tools that still use this library, and it’s good learning material for whoever wants to learn about implementing API’s. While it’s good to learn about this library since it’s ubiquitous, if you are starting fresh, we recommend IB’s official python SDK. is even much simpler to use! Alpaca Trade API Python SDK Analytical Tools: Back testing will output a significant amount of raw data. Some IDE’s will provide basic visualization and analysis, usually algorithm performance. If you’re looking for deeper evaluation, I recommend these tools: (7) : Pyfolio _pyfolio - Portfolio and risk analytics in Python_github.com quantopian/pyfolio Pyfolio is another open source tool developed by Quantopian that focuses on evaluating a portfolio. What sets Pyfolio apart, is its ability to introduce degrees of uncertainty to a static set of data points, and evaluate Bayesian metrics from the user’s portfolio. The Pyfolio API offers a number of visualizations, which can be found on their GitHub repository. (8) : Alphalens _alphalens - Performance analysis of predictive (alpha) stock factors_github.com quantopian/alphalens Alphalens is also an analysis tool from Quantopian. Unlike Pyfolio, Alphalens works well with the raw data output from Zipline, and rather than evaluate the portfolio, is performance analysis of predictive stock factors. Alphalens has its own range of visualizations found on their GitHub repository. Median Daily Returns by Factor Quantile — one of the visualizations that alphalens offers (9) : TradingView TradingView is a visualization tool with a vibrant open-source community. It’s entirely web-based, and allows users to visualize data, whether the data is the result of paper trading or algorithmic back-testing. Like Quantopian, TradingView allows users to share their results and visualizations with others in the community, and receive feedback. (Bonus) Execution Platforms aka Broker-Dealers: (10)InteractiveBrokers: InteractiveBrokers is an online broker-dealer for active traders in general. They have been in the market since 1978. Algo trading isn’t IB’s focus, but multiple engines offer live trading through integration with their Trader Workstation. We’ve mentioned IB several times in this article — they’re just that good! (11)Alpaca: Finally, Alpaca! Alpaca was founded in 2015, and is an up and coming commission-free, broker-dealer designed specifically for algo trading. Alpaca also has a trade api, along with multiple open-source tools, which include a database optimized for time-series financial data known as the .
