In crypto trading i never calculate trading fee because that small percentace from target profit, i have minimum 7% pertrade for taking profit. Lets say i make profit 7% per trade and reduce it with trafing fee 0.1% so my total profit will be 7-0.1 = 6.9%.
easiest solution from all othersim using other one, from all my trades daily i subtract constant % amount becaue after all average is pretty much accurate, also its like spending $1000 in market, u don't care about pennnies then do you?
if you really want to be accurate, save all your trades in excel sheet with simple equations to calculate fee's automatically
