The profit/grid percentage is already deducted with fee or they will charge fee? and if I run my bot just like this, will I still get profit if the fee is 0.05%?

Answer

All transactions made by the trading bots on Pionex are fees inclusive therefore grid profits already have the fees deducted hence there wont be any other fee. Pionex Exchange provides one of the affordable fees in the cryptocurrency market , hence it can be capitalized upon to make more profits since you per less for all transations
