This is a simple backtesting framework to help you test your crypto currency trading. It includes a way to download and store historical crypto data and to execute a trading strategy.
From what I can see it still has trading for 1 coin
ie if backtesting on ETH, each trade will be 1ETH in size
trade_size = 1
Needs to be for a total amount. So if the account balance is $100,000 each trade could be lets say $5k. When coin price fluctuates the gains are skewed.
