short_macd_threshold_par (int):
The threshold of normalized macd, below which we might open a short position
short_per_threshold_par (int):
The value of percentage change over the last 2 hours below which we might open a short position
short_close_threshold_par (int):
Threshold of normalized macd, above which we will close the opened short position
initial_cash (int) (optional):
The cash to start from. Initiall 10k
comission (int) (option):
int fraction value. Defaults to 0.1%. This is much higher than normal. Staying on the safe side.
df (Dataframe) (option):
Uses df as features dataframe if specified. Otherwise reads the coin folder
