Formula
Buy Amount = buyPrice × qty
Sell Amount = sellPrice × qty
Fees = (Buy + Sell) × fee%/100
Tax = Sell × tax%/100
Profit = Sell − Buy − Fees − Tax
Return % = Profit ÷ Buy × 100
Buy Amount = buyPrice × qty
Sell Amount = sellPrice × qty
Fees = (Buy + Sell) × fee%/100
Tax = Sell × tax%/100
Profit = Sell − Buy − Fees − Tax
Return % = Profit ÷ Buy × 100
