Hello,
Marcin somehow did not see the obvious - you have set non-zero interest rate that's why you get such results
(interest rate is calculated from "remaining" money and "remaining" money is different in "all", "short" and "long" columns
so clearly profit figures can sum the way you think). Set "interest rate" in the Settings to zero and then you will get the results
you were expecting.
Best regards,
Tomasz Janeczko

Hi terry,
I have been going back and forth with Marcin all day long....We simply can NOT get it to function correctly.Not only that,if I run LONG trades only from settings,I am still getting P&L from short trades under reports..
If I run short trades only,I am still getting p&L from the long trades under reports..Even more bizzare is the same P&L number is poping up when it shouldnt....Plus the net trades do not = short +long p&L...
The code was very simple and he has checked my settings and code..I will send along some attatchments,but please bare with me..I am a programming IDIOT!!!
Allan
