We also strongly advise that you thoroughly test this project, its settings and algorithms with a paper trading account. we accept no liability whatsoever in the usage of this project in accordance with the provided license.

The RoboBull Trading Bot is a fully automated trading bot which analyses stock market data with a variety of technical indicators. Technical indicators are mapped to specified weightings which determine whether a signal (BUY/SELL) is generated. If an overall weightings threshold is met, based on generated signals, an order is created.

The bot currently supports both live trading (paper account recommended) and historical back testing via Alpaca's API as an integrated trading provider and plan to support others in the future.

We've integrated our Stock Screener into this project which provides market analyses and top performing stocks. We aim to provide this data for FREE as long as we can. Donations welcome for upkeep!

Tip: If you don't want to use our stock screener you can simply disabled it by setting useStockScreener to false.

Tip: If the US markets are closed then you can use back testing instead.

• Install using Docker Compose which requires you to install Docker:

• Go to Alpaca and sign up for a free account. We recommend paper trading only for using this project. You don't need to spend real dollars to test this project. Once you have a paper trading account you can create your API key and secret which will be needed in the next step.

• Copy .env-example and rename to .env and then add your Alpaca key (API_KEY) and secret (SECRET_API_KEY). Important: keep your key/secret locally, don't commit it or share with anyone.

• Ensure you have edited your settings.json for live/paper trading or back testing

• Run docker-compose up

• Create a new user by going here: (http://localhost:3000/create-user). You'll then be redirected to the trading terminal. You only need to create a new user once.

• Once you've created a new user, you can re-run the trading bot in the future by visiting (http://localhost:3000/run). However, you may need to stop the docker container and start it again to rerun the trading bot (this is due to only 1 connection allowed per trading account on Alpaca).

• You can also visit (http://localhost:8081) to view and manage MongoDb data

It's worth familiarizing yourself with the basic settings before you run docker-compose up during the installation. You can find all settings and their explanations later in this readme.

Tip: You need to restart your Docker container each time you make a change to your settings or code. Just Control-C out of the current process and then docker-compose up again.

• provider alpaca - trading provider to use (currently only Alpaca is available)
• isPaper true/false - to use paper trading account (default: true)
• isBacktest true/false - to use back testing functionality (default: false)

Tip: All positions will automatically close (sell) 15mins before end of the market closing. It may be beneficial to keep your positions, especially if you're at a loss, but its completely up to you. If you wish to do so, set useClosePositionsBeforeMarketClose to false (then restart the docker process).

Edit your stock symbols/tickers in this file. The stocks will be used as your default stocks for live trading as well as the stocks used for back testing (if enabled).

The algorithms / technical indicators are massively customizable and have been tested for optimal performance. It may be better to retain the current setup and use the basic properties below until you have spent time analysing your trading ROI (both live/paper and back testing).

• thresholdToBuy 35 - overall weightings threshold from signals to trigger a BUY order
• thresholdToSell 25 - overall weightings threshold from signals to trigger a SELL order
• useStandardAlgos true/false - to use standard technical indicators like bullish/bearish patterns (default: false)

Feel free to tweak the settings in algo.json file as much as you like. A more detailed explanation of algo settings is coming soon. Tip: You may want to increase the thresholdToBuy setting to 40 which will tell the bot to be stricter when buying stocks.

This feature allows you to run both live/paper trading and back testing without the need of a web browser. In order to do this open a terminal tab:

• Run docker-compose up

Then open another terminal tab:

• Run docker exec -it $(docker ps -aqf "ancestor=trading-bot_app") npm run console

Change the following in settings.json, then re-run docker-compose up and go to http://localhost:3000/run

• provider make sure this is set to alpaca
• isPaper make sure this is set to true
• isBacktest make sure this is set to true
• startingCapital set this to the amount you wish to start back testing with (currency is always set to USD)
• startDate set your start date for back testing
• endDate set your end date for back testing

• provider alpaca - trading provider to use (currently only Alpaca is available)
• isPaper true/false - to use paper trading account (default: true)
• isBacktest true/false - to use back testing functionality (default: false)
• resetSignals true/false - to reset signals after calculating signals (default: true)
• startingCapital 100000 - starting capital (used during back testing)
• thresholdCapitalAllowance 10 - how much capital allowance usage to calculate portfolio percentage (reduces percentage)
• thresholdRiskAllocation 2 - how much risk allocation to apply to portfolio percentage (multiplies percentage)
• thresholdCapitalRetention 10000 - how much capital to retain during trading
• thresholdBuyCap 0.12 - how much capital any given trade can amount to
• thresholdBuyTimeRestriction -60 - how long in minutes a position must be held before being sold
• thresholdStockCap 15 - how many positions can be held at once
• orderStopLoss -0.006 - how much a position can lose in return on investment before selling
• orderTakeProfit 0.008 - how much a positions can gain in return on investment before selling
• orderHoldUntilProfit false - whether to stop selling a position at a loss (holding until profit)
• roiToClosePositions 0.3 - how much the overall ROI must be over to close all current positions and end trading
• roiToResetPositions -0.5 - how much the overall ROI must be below to gradually close poor performing positions (currently disabled / needs refactoring)
• startDate "2021-02-01 00:00:00" - start date used for back testing
• endDate "2021-02-01 00:00:00" - end date used for back testing
• useClosePositionsBeforeMarketClose true/false - closes/sells all open positions before market is closed (default: true)
• usePreviousUserSession true/false - to use previous user's session (no longer exists, default: false)
• useDefaultStocks true/false - to use a list of stocks by default and also required for back testing (default: true)
• useStockScreener true/false - to use a list of high performing stocks from RoboBull Stock Screener every 15mins to ensure that best stocks are used during live/paper trading (default: true, fallback if empty is to use default stocks)
• useStockQuotePercentage true/false - to use Financial Modeling Prep API for latest stock percentage change before ordering. Requires third-party API key. (default: false)
• stockQuotePercentageChangeRangeTo 15 - how much of a percentage that a stock's change can be increased up to when processing order. This is to help against volatile stocks along with pump and dumps (only used during live/paper trading)
• stockQuotePercentageChangeRangeFrom 1 - currently not used

The code follows mostly the standard structure used within Express Framework related projects.

We love these dependencies to speed up development!

We are currently working on more Unit tests but the setup for robust tests are in place.

• First you'll need to install Node v12. We recommend using Brew to install NVM which will allow you to switch between different Node versions locally. Go to your console / terminal: brew install nvm
• Make sure you're currently running Node v12 using node --version
• Install dependencies using this command: npm install
• To run unit tests (with code coverage), use this command: npm test

• Progressive Stop Losses.
• Make all methods asynchronous with Try/Catch.
• Tidy views inc. frontend Javascript (potentially split out frontend as a separate service)
• Add more algos / technical indicators (Extrema would be great!).
• Optimized Mongodb methods.
• Unit tests
