This is the source of the Crypto currency trading bot running on:

It is written in TypeScript for NodeJS + MongoDB.


  • Trading: buying + selling, portfolio management (sync balances with exchanges)
  • Margin Trading: leveraged trading including short selling and futures trading
  • Arbitrage: profit from price differences between 2 exchanges (done "on the books" with balances on both exchanges, no withdrawals from exchanges required)
  • Lending: lend your coins on the lending market of supported crypto exchanges for the highest possible interest rates
  • Backtesting: test your trade strategies in simulation on historical data
  • Web Plugins: Access social media data from Twitter, Reddit, Telegram Channels, RSS Feeds,... to trade based on news and real world events (not part of open source version yet)

Getting Started


NodeJS >= 10
MongoDB >= 3.4
TypeScript >= 2.8
yarn >= 1.9.4 (npm should work too, but no support given if you run into errors)
Webpack >= 4 (only for UI modifications)


git clone
yarn install

You can use the --production flag if you only want to run the bot and not make any code changes.

Start trading

Rename the configLocal-sample.ts file in the project root directory to configLocal.ts and add at least mongoUrl (plus some exchange API keys if you want to trade).

After running TypeScript (automatically in your IDE or run the tsc command in the project root dir) you will see a file:


tsc will show you some errors (due to shared code with missing types between server and client side, I will refactor this later). Just ignore these errors and make sure noEmitOnError is not set (the default) and that you have a build/ dir in the project root as well as for all packages under node_modules/@ekliptor which contain a tsconfig.json file. Use the build directory as the working directory and run:

node app.js --debug --config=Noop --trader=RealTimeTrader --noUpdate --noBrowser

The config parameter must be a JSON file from the config directory. For a list of all parameters look at the top of the app.ts file.

Writing your own trading strategies

There is documentation available here:

Look into the /src/Strategies folder for more examples.

Modifying the UI

In the project root directory, run:

webpack --progress --colors --watch

You should also run the bot with the --uiDev flag so that changes to HTML template files are reloaded from disk.

The UI uses a single persistent WebSocket connection. UI related code is in the following directories:

├ project root
├─── public <- all code shipped to the browser
├────── js <- all TypeScript code to be compiled with WebPack
├─── src
├────── WebSocket <- all server-side logic to push updates to the browser
├─── views <- all HTML templates

REST and WebSocket JSON APIs

If you want to connect WolfBot to your trading terminal, please take a look at the API docs.

This let's you:

  • create new cloud bot instances and earn commission for every referral (not applicable to open source version)
  • import the trades book with all trades WolfBot made via REST API call
  • subscribe to live trades via WebSocket to display them in your trading terminal
  • subscribe to live strategy data and indicator values via WebSocket
