Download Gekko trading bot
A bitcoin trading bot written in node

Gekko is an open source platform for automating trading strategies in the Bitcoin markets. Define your own trading strategy, and Gekko will take care of the rest. Gekko is free and 100% open source, you download and run the software on your computer. Gekko only negotiates with exchanges (if that's what you want too). We don't know anything about your strategies, usage, portfolio size, or anything else (until you tell us). Gekko supports 16 different exchanges (including Bitfinex, Bitstamp and Poloniex). Just tell Gekko which exchange you want to interact with, and Gekko will contact the exchange directly. Gekko allows you to create your own trading strategies using TA indicators. Once you have created it, you can use Gekko to test your strategy on historical market data or on the real market (using either a paper trader or a real trader - turning it into a trading bot).
