I've attached an extreme example of where there is a clear difference between daily equity and realised profits and losses (balance). In this example, Ret/DD = 19.58 and PF = 3.08, but the reality (red line) will be far worse.
There are plenty of more normal strategies where this would be useful where building on higher timeframes like H4 and above where trades can be open for a long time.
PLEASE remember to also include the addition of SWAPS (very important): https://roadmap.strategyquant.com/tasks/sq4_3847
