A trade’s final result reflects its actual entry and exit prices and any separately charged fees. Looking at the full calculation helps prevent surprises.
The idea
Start with the actual filled buy and sell prices and multiply their difference by the quantity, according to the instrument’s contract specifications. Those actual prices already reflect the spread and any slippage in the fills, so do not subtract them again. Then subtract separately charged commissions and financing, or add a financing credit. Currency conversion and other fees may also apply.
Apply the idea
Suppose you buy 10 units at an actual ask fill of $100.05 and sell at an actual bid fill of $103.00. The price result is $2.95 per unit, or $29.50. If commission is $2 on entry and $2 on exit, and an overnight charge is $1, the net result is $24.50. This example assumes no other charges or currency conversion.
Key takeaway
Use actual fills, then account for separately listed charges and credits. Review the provider’s trade history and fee schedule to understand your final result.
