This bot wuill maintain a specific proportion of each asset value as you set. If you set ETH value to 25%(0.25) of portfolio, deviation to 0.1, bot will buy to 0.25 when the value ratio is below 0.90.25 and sell when it is above 1.10.25, thus, the ETH value is kept to a certain ratio. Balancing more than one asset, you have to add trading pair separately, and ratios is input like "0.25
