If I go long 1 lot and it loses 100 pips, but go short 3 lots and it wins 50 pips, by a fixed calculation of pips, I'm down 50 pips. However I won $50 So in reality I should be showing a win of 50 pips overall. The calculation would be (3 * 50) - (1 * 100) = 50. Pip calculations should take lot sizes into account and from what I see on the charts that display pips won/lost they don't. I'll see for any given day when the account is up, the pips calculation is negative.
