This project is not maintained anymore.

After many years of working on Gekko, I’ve decided to stop my involvement in maintaining this project. You can read more about this decision on medium.

I’m now putting all my focus on my new prop trading firm Folkvang. You can find an article about that here on Coindesk.

If you’re interested in following this new journey, feel free to add me on Twitter.

Best of luck to everyone in their trading. So long, and thanks for all the fish!

Enabling plugins #

Note: this documentation was written for running Gekko via the command line. If you are using the UI you do not have to manually select plugins.

Gekko currently has a couple plugins:

To configure a plugin, open up your config.js file with a text editor and configure the appropiate section.

Trading Advisor #

If you want Gekko to provide automated trading advice you need to configure this in Gekko. Note that this is a different plugin than the "trader" which is a responsible for actually creating orders based on this advice. (So if you want automated trading you need both this advice as well as the auto trader).

Documentation about strategies in Gekko can be found here.

Trader #

This plugin automatically creates orders based on the advice from the "Trading Advisor" from the market Gekko is watching. This turns Gekko into an automated trading bot.

Before Gekko can automatically trade you need to create API keys so that Gekko has the rights to create orders on your behalf, the rights Gekko needs are (naming differs per exchange): get info, get balance/portfolio, get open orders, get fee, buy, sell and cancel order. For all exchanges you need the API key and the API secret, for both Bitstamp and you also need your username (which is a number at Bitstamp).

Configure it like this:

config.trader = {
  enabled: true,
  key: 'your-api-key',
  secret: 'your-api-secret',
  username: 'your-username' // your username, only fill in when using bitstamp or cexio

Advice logger #

The advice logger is a small plugin that logs new advice calculated by Gekko as soon as there is any. Go to the config and configure it like this:

config.adviceLogger = {
  enabled: true

The advice logged advice will look something like this in the terminal:

2014-01-15 14:31:44 (INFO): We have new trading advice!
2014-01-15 14:31:44 (INFO):    Position to take: long
2014-01-15 14:31:44 (INFO):    Market price: 5.96
2014-01-15 14:31:44 (INFO):    Based on market time: 2014-01-15 14:31:01

Paper trader #

The paper trader listens to Gekko's advice and on a sell it will swap all (simulated) currency into (simulated) assets at the current price. On a buy it will be the other way around.

Go to the config and configure it like this:

// do you want Gekko to calculate the profit of its own advice?
config.paperTrader = {
  enabled: true,
  // report the profit in the currency or the asset?
  reportInCurrency: true,
  // start balance, on what the current balance is compared with
  simulationBalance: {
    // these are in the unit types configured in the watcher.
    asset: 1,
    currency: 100
  // only want report after a sell? set to `false`.
  verbose: false,
  // how much fee in % does each trade cost?
  feeMaker: 0.5,
  feeTaker: 0.6,
  // Using taker or maker fee?
  feeUsing: 'maker',
  // how much slippage should Gekko assume per trade?
  slippage: 0.1

*If you are trading a lot and you are buying 100% currency you might not get it all at market price and you have to walk the book in order to take that position. Also note that Gekko uses the candle close price and is unaware of the top asks bids, also take this into account. It is important that you set this number correctly or the resulted calculated profit be very wrong. Read more information here. Take these into consideration when setting a slippage:

The output will be something like:

2013-06-02 18:21:15 (INFO): ADVICE is to SHORT @ 117.465 (0.132)
2013-06-02 18:21:15 (INFO): (PROFIT REPORT) original balance:    207.465 USD
2013-06-02 18:21:15 (INFO): (PROFIT REPORT) current balance:     217.465 USD
2013-06-02 18:21:15 (INFO): (PROFIT REPORT) profit:          10.000 USD (4.820%)

Mailer #

Mailer will automatically email you whenever Gekko has a new advice.

// want Gekko to send a mail on buy or sell advice?
config.mailer = {
  enabled: false,       // Send Emails if true, false to turn off
  sendMailOnStart: true,    // Send 'Gekko starting' message if true, not if false

  Email: '',    // Your GMail address

  // You don't have to set your password here, if you leave it blank we will ask it
  // when Gekko's starts.
  // NOTE: Gekko is an open source project < >,
  // make sure you looked at the code or trust the maintainer of this bot when you
  // fill in your email and password.
  // WARNING: If you have NOT downloaded Gekko from the github page above we CANNOT
  // guarantee that your email address & password are safe!

  password: '',       // Your GMail Password - if not supplied Gekko will prompt on startup.
  tag: '[GEKKO] '      // Prefix all EMail subject lines with this

IRC bot #

IRC bot is a small plugin that connects Gekko to an IRC channel and lets users interact with it using basic commands.

config.ircbot = {
  enabled: false,
  emitUpdates: false,
  channel: '#your-channel',
  server: '',
  botName: 'gekkobot'

Campfire bot #

Campfire bot is a small plugin that connects Gekko to a Campfire room and lets users interact with it using basic commands.

config.campfire = {
  enabled: false,
  emitUpdates: false,
  nickname: 'Gordon',
  roomId: 673783,
  apiKey: 'e3b0c44298fc1c149afbf4c8996',
  account: 'your-subdomain'

Redis beacon #

This is an advanced plugin only for programmers! If you are interested in this read more here.

config.redisBeacon = {
  enabled: false,
  port: 6379, // redis default
  host: '', // localhost
    // On default Gekko broadcasts
    // events in the channel with
    // the name of the event, set
    // an optional prefix to the
