Install

$ git clone [email protected]:cleanunicorn/magictune.git
$ cd magictune
$ pip install -r requirements.txt

It's recommended to use virtualenv if you're familiar with it.

Requirements:

• Python 3.5 or higher
• Kraken account and API key

Configure

Copy the config sample and edit it.

$ cp config.json.sample config.json

Example config:

{
    "kraken": {
        "key": "KRAKEN-KEY",
        "secret": "KRAKEN-SECRET"
    },
    "assets": [
        {
            "name": "Ethereum",
            "symbol": "XETH",
            "pair": "XETHZEUR",
            "min_threshold_percent": 0.1
        },
        {
            "name": "Litecoin",
            "symbol": "XLTC",
            "pair": "XLTCZEUR",
            "min_threshold_percent": 0.1
        }
    ],
    "absolute_asset": {
        "name": "Euro",
        "symbol": "ZEUR"
    },
    "strategy": "shannon"
}

Setting up Kraken API

You need to replace KRAKEN-KEY and KRAKEN-SECRET with your own generated key. The key needs to have these permissions:

• Query Funds
• Modify Orders

Make sure not to use your Kraken account once the bot is running or it will mess it up. It uses the balance and the current asset prices to figure out what to do next. If you place orders or add new funds in your account it will use those too.

Setting up assets

Setting up the assets requires a bit of work.

Run in mode asset-pairs to figure out how to configure each asset.

$ python magictune.py asset-pairs | jq | less

Configure absolute_asset first. This is the asset which you consider to be non-fluctuating. All other assets pairs will be configured in reference to this.

"absolute_asset": {
    "name": "Euro",
    "symbol": "ZEUR"
},

After you configured absolute asset you need to configure assets. Each asset looks like this:

{
    "name": "Ethereum",
    "symbol": "XETH",
    "pair": "XETHZEUR",
    "min_threshold_percent": 0.02
}

The pair field needs to have the asset symbol first and the absolute asset second (i.e. XETHZEUR).

The min_threshold_percent defines what is the minimum trade percent (0.01 equals 1%, 0.1 is 10% and so on). You can set it as high as you want but no lower than the values defined here, otherwise it will fail trying to make trades. It's not a critical problem because the trade just won't happen.

Running

The bot does not continuously run. A cronjob can be set. For example to run every hour, you can set this job.

Open your crontab to edit jobs:

$ crontab -e

Add this line:

0 * * * *       cd /path/to/magictune && python3 magictune.py run 2>&1 >> /var/log/magictune.log 

Your log file will look something like this:

[Tue Jul 16 14:01:51 2019] Doing trade buy 1.23456789 @ 4321 = 9876 ZUSD
{'error': [], 'result': {'descr': {'order': 'buy 1.23456789 XBTUSD @ market'}, 'txid': ['AAAAA-BBBBB-CCCCC']}}
