Gekko

The most valuable commodity I know of is information.

-Gordon Gekko

Gekko is a Bitcoin trading bot and backtesting platform that connects to popular Bitcoin exchanges. It is written in javascript and runs on nodejs.

Use Gekko at your own risk.

Main features

Automated trading (trade bot)
Paper trading (for TA strategies)
Backtester (for TA strategies)
Tool for systematic trading
Low level market library
Monitor the live market
Import historical market data
Broadcast market data over pubsub messaging systems

TA strategies

Gekko comes with some basic strategies (which implement a single indicator). But with some basic javascript you can create your own strategies. You can use over 130 indicators to create your perfect prediction model (full list of supported indicators). Why don't you combine Bollinger Bands, CCI and MACD with a STOCHRSI indicator?

Automated Trading platform

Gekko can watch the realtime markets, you can apply automated trading methods to do live or simulated trading (automated trading or paper trading). Gekko stores all market data it sees, this makes it possible to simulate trading strategies against historical data to see whether they would have been profitable (backtesting).

Gekko is not built for HFT or anything related to being the fastest (like arbitrage). The trading methods Gekko can do are based on TA indicators used by human day traders. This means that Gekko does not look at data below the one minute timescale and will not trade more than a couple of times per week (depending on configuration).

So Gekko is not:

A trading platform for human day traders with a GUI and charts.
A High frequency trading bot designed to operate on < minute resolution.
A fully automated trading bot that you turn on and will generate profit without you having to do anything.
An exchange.
An arbitrage bot.

Monitoring means that Gekko is able to watch the realtime market and thus also:

Run trading strategies against the data (in semi-realtime)
Simulate trading profits (paper trader)
Store all data (to backtest in the future)

Installing Gekko

Better documentation for TA-lib indicators.
More indicators (maybe use this native js lib?)
Webbased interface (first step)?
