Formula and assumptions
For a linear Forex position, gross P/L = position units × signed price difference × quote-to-account conversion. A long position uses exit minus entry; a short position uses entry minus exit. Estimated net P/L = gross P/L minus the costs supplied by the user.
Costs are a single user-entered total in account currency. This page does not fetch spreads, commissions, swaps, execution prices, or conversion rates. It is not suitable for non-linear or non-Forex contracts.
