Frequently asked questions
How is option profit or loss estimated?
For a long option, estimated gross result = (exit premium − entry premium) × units. For a short option, reverse the difference. The calculator then subtracts charges you enter.
Does the option calculator predict market prices?
No. It only calculates a result from the prices and quantity you enter; it does not forecast option prices or returns.
Are taxes and brokerage included automatically?
No. Enter total charges for your trade. Actual costs depend on your broker, product, exchange and current rules.
