Choose a calculator for your task
The position-size calculator converts a chosen loss budget into a whole number of contracts. It includes stop distance, tick value, estimated slippage and costs per contract. The profit factor calculator compares total positive trade results with the absolute total of negative results.
Inputs determine what the result means
Use the same cost basis and period for winning and losing results. Fees and slippage in the position calculator are assumptions you must adjust to your trading. The resulting budget is not a guaranteed loss limit and does not replace a broker margin check.
