Description

Reads price on a big exchange and places orders on a smaller exchange with larger spread taking advantage of slippage.

Built so everyone runs their own bot. There's no reason to introduce more trusted parties like other people's servers.

Status

Testing. No GUI or front end yet, edit settings.json to control instead.

Instructions

Requires

• Node.js v10
• Text editor to create and edit the settings.json and auth.json in project root folder (e.g. vscode, gedit apt install gedit)
• Uncertain: I had to enable ntpd for more accurate clock on Linux Ubuntu 18.04 or it would have issues rapidly placing orders (instructions)

To clone this codebase, type this where you want the codebase folder to appear:

git clone https://github.com/ildarmgt/arbot.git arbot

Install dependencies

cd arbot
npm install

Create auth.json & settings.json

Need api keys for exchanges used for trading placed in a file in project root folder called auth.json

Create it however (e.g. touch auth.json) and paste keys inside (e.g. gedit auth.json) like this example for cryptopia:

{
  "cryptopia": {
    "PUBLIC_KEY": "public key here",
    "PRIVATE_KEY": "secret private key here"
  }
}

Also need initial settings file (like what bots to run initially). In project root folder, create settings.json (e.g. touch settings.json). Fill (e.g. gedit settings.json) with something like this example for 2 trading bots plus BTCUSD price fetching:

{
  "bots": [
    {
      "type": "info",
      "botStepDelay": 30000,
      "coin1": "BTC",
      "coin2": "USD",
      "sourceRef": "bitstamp",
      "sourceRefDelay": 1000
    },
    {
      "type": "arbot",
      "botStepDelay": 30000,
      "coin1": "XMR",
      "coin2": "BTC",
      "sourceRef": "hitbtc",
      "sourceRefDelay": 1000,
      "sourceTrade": "cryptopia",
      "sourceTradeDelay": 300,
      "offsetPercent": [0.5, 0.6],
      "positionFraction": [0.50, 0.49],
      "minSTDEV": 0.25,
      "offsetSTDEV": [1, 2],
      "leadsSharedEvents": true
    },
    {
      "type": "arbot",
      "botStepDelay": 30000,
      "coin1": "LTC",
      "coin2": "BTC",
      "sourceRef": "gdax",
      "sourceRefDelay": 1000,
      "sourceTrade": "cryptopia",
      "sourceTradeDelay": 300,
      "offsetPercent": [0.45],
      "positionFraction": [0.9],
      "minSTDEV": 0.25,
      "offsetSTDEV": [1.5],
      "leadsSharedEvents": false
    }
  ]
}
