Config

Create a config file in config.ini with definition of your exchange and portfolio percentages, and theshold (percent) that rebalancing is needed. An example config file is included at config.ini.example but below is all you need:

[binance]
api_key = <api key>
api_secret = <api secret>
threshold = 2.0
targets = XRP 40
          BTC 20
	  ETH 20
	  BNB 10
	  USDT 10

By default it values the portfolio in USDT, this can be changed with --valuebase argument.

Running automatically

You can set this to run in a cron job on a unix system by putting something along the lines of (adjust for your path and email address) below in your crontab file:

MAILTO=matt@example.com
*/5 * * * * OUTPUT=`cd /home/matt/crypto_balancer; bin/crypto_balancer --trade binance`; echo "$OUTPUT" | grep -q "No balancing needed" || echo "$OUTPUT"

This will run the script every 5 minutes, and will email you only if some balancing (or an error) occurs.
