Thanks a lot Keith for your suggestion on my code.

I request please could you advise/guide/suggest on how to read profit part of indicator iExposure from any EA using iCustom() function. how to check for any errors when I am trying to read values from indicator with iCustom function.

when I am using below code to read values from indicator there were no errors. there is no out put as well

double pl=iCustom(NULL,0,"iExposureSymbol",Red,1,0);

below is the indicator code:

Many thanks in Advance

The indicator only uses 1 buffer, ExtMapBuffer[], and when I say use, it doesn't actually use it for anything.

just

//---- to avoid minimum==maximum
   ExtMapBuffer[Bars-1]=-1;

So an iCustom call is no use at all with the indicator as it is.

double pl=iCustom(NULL,0,"iExposureSymbol",Red,1,0);

checks buffer 1, when as there is only 1 buffer it would have to be 0. It still would be no use though as explained above.

thanks for your advise Keith,

I have been trying to get the floating p/l from the attached EA. I tried many ways to get the currency wise floating pl from this EA. In my all afforts, OrderProfit() is not getting sum of more than 2 orders.

please could you help/suggest/guide/advise on how to get floating pl from this attached EA. Different types of code which I tried so far is working from other EAs but not from this attached EA

Your code is an indicator and would need to use the EA's magic number to filter trades.

Your script "is displaying floating p/l on the chart." It is working. You don't modify it. It is done.

You write another indicator or EA to use iCustom to read the buffer.

thanks for your reply whroeder1,

when I tried to access the p/l value from my ea using the below command it is displaying different results.

double pl = 0;

pl=iCustom(NULL,0,"profitind",0,0);

please advise;
