Anytime when it is not a simple in and out trade but averaging in and out, the P/L is incorrect and by a lot! Instead of +700 I got -100 and so. Today I already submitted 3 tickets, they have been corrected but I still found 2 more trades where the P/L is off by about $200-200 but I don’t even worry anymore since it is just a test system. The mistake is always against the system by the way…
What I don’t get is, why is this such a big problem after more than a decade? It is a simple calculation, averaging the ins and outs and multiplying it with the tick value. End of story, or it should be. I am really dumbfounded by this kind of problems existing…
