The Coin Signals trader is meant to allow anyone to quickly and easily set up an automated trading bot. This bot relies on Signals which are supplied via Slack in the Universal Signal Format. This project doesn't generate it's own signals, it only acts on ones that it receives.

I run a signal generation service on Slack that you're welcome to use for testing. Join us in Slack to see the signals (in #signals), chat, and get help.

This is a free project, so if you'd like to support my work, I'd really appreciate that.

• BTC - 1E6Vyh84pTEP9v6Sh8Yzm693pBZLvguX3m
• ETH - 0xb2921b476838c8DB9a29d708B3cA8c11959D7c7D
• LTC - LfkD8jcgv4E2rDta4hA2CUHNMiPGdZL1yr

• Node.js (Version 6 and up recommended)
• Bittrex API Key
• Slack

• Clone down the repository.

git clone https://github.com/snollygolly/coin-signals-trader.git

• Install packages (from inside the coin-signals-trader folder).

npm install

• Create your config. There's a config.json.example file in the root. Edit it to include all your values. Refer to the configuration breakdown for more information about what does what. Save it as config.json and leave it in the root.

Note: You will need to choose a password to complete the initial set up. Make sure it's something people aren't likely to guess

• Seed your database

npm run seed

• Run the bot!

npm start

• Private message the bot in slack to get started and follow the directions from there

The bot responds to several commands via Slack private message:

• !buy PAIR PRICE QTY

Example: !buy BTC-LTC 0.009 1

• !sell PAIR PRICE

Example: !buy BTC-LTC 0.0095

Note: This command will automatically sell all coins you've purchased through the bot.

• !portfolio

Example: !portfolio

Note: Using this command will show you some basic statistics about your portfolio. This command is fairly basic for the time being, but it will show you how many trades you've made, and how you are doing overall.

• !writeoff PAIR

Example: !writeoff BTC-lTC

Note: Using this command will refund the cost of the buy for this pair. It will also remove it from your porfolio. This can be useful if you'd like to continue to hold a position and the bot is prepared to sell it. It doesn't actually sell or refund the position, only on paper.

• !halt

Example: !halt

Note: If you don't want to take on any new positions or sell any currently held positions, you can halt trading with this command.

• !resume

Example: !resume

Note: If trading is halted, you can resume it with this command.

• !exit

Example: !exit

Note: You'd think it would exit the bot, but it doesn't doesn't. It's poorly named. It will actually prevent you from accepting new orders, but it will allow you to exit out of existing orders.

• !ping

Example: !ping

Note: Says "Pong".

Signals are sent via Slack and are expected to be in the correct format:

^ACTION*PAIR*QUANTITY*PRICE*META^

• Action (Required) This is the action you want the trader to take

  • BUY
  • SELL

• Pair (Required) This is pair you want to trade (like BTC-LTC)

• Quantity This is how many coins you want to affect in this signal. If you'd like the trader bot to use it's defaults, you can pass "A"

• Price This is the per coin price you want to use for this signal. If you'd like the trader bot to use it's default, you can pass "A"

• Meta If you'd like to attach addition information to your signal, you may do it here. The symbol * may not be used in meta information though. This string will be used to create filenames for your trades. It's suggested that you supply a unique string for each signal. Timestamps are a good choice.

BUY*BTC-LTC*1*0.01*0001

This signal would buy 1 Litecoin (BTC-LTC) for 0.01 BTC. It would also includes some meta information (0001).

SELL*BTC-LTC*A*A*0002

This signal would sell the default amount of Litecoins at the default price. It also includes meta information (0002)

    |-- config
    (contains all the settings for customizing the bot's behavior)
    |-- services
    |-- config.json
    (contains all configuration values, more on that later, it must be created)

The configuration file for the bot project is fairly simple and consists mainly of settings for Slack and Bittrex:

{
  "name": "Coin Signals Trader",
  "bittrex": {
    "api_key": "XXX",
    [your bittrex key for trading]
    "api_secret": "XXX"
    [your bittrex secret for trading]
  },
  "slack": {
    "name": "Coin Trader",
    [the name of your bot]
    "secret": "XXX",
    [from your slack app]
    "channel": {
      "name": "signals",
      [the name of the channel you'll join, without the pound sign]
      "id": "C86832X08",
      [the id of the channel you'll join]
      "bot": "B86C7N9UH"
      [the id of the bot sending signals]
    },
    "password": "changeme"
    [the password you'll need to first time setup of the bot]
  }
}

This configuration lives in config/trading.js
