sum proft&loss

Hi all,

I use this code to obtain the result shown here .
The function TradeProfit seems doesn't works.

Code:

for(open_trades)
{
	val += TradeProfit;

print(TO_WINDOW,"n %s - p&l = %4.2f",Asset,val);
}

If I want obtain the sum of all these cross how can I modify the code above?

Thanks in advance
