Why is my EA gray?

May I ask question why in the Expert Advisors list my EA looks gray instead of to be colorful. Thanks.

You don't have the source code of that EA

I have source code. What should I do with this?
In the past there were only ex4 files without source code and
the EAs were colorful.

EA's without source will always be grey. If you have the source then load it and recompile - the icon will become full color.

Thank you,guys.
This forum is really good.

It may be you have an error when compiled, have you checked its clean

It hasn't been compiled (without a .ex4 I believe) or wasn't compiled correctly. Try opening it up in the Meta Editor and compiling it and see what happens.

Yes, I believe so. If EA is gray it means some error in the code.

I run an EA and it does not make trades. Looks like everything works good.
I run on Alpari platform.
When I looked at the journal I found
unknown command 3C.
Appreciate if some strong programmer can help.
Thanks.

When I run strategy tester the trades are placed.
When it is in forward testing, it does everything except
placing trades and gives error
4060 that means Function is not confirmed.
Can anybody please help?
Thanks a lot.

Can some programmer please help me with csv.
H= FileOpen("D.csv",FILE_READ | FILE_WRITE,';');
opened the file and
write it
FileWrite(H,Open[0]);
with double H declared
but
double C;
if(H>0)
{
C=FileReadNumber(H);
FileClose(H);
}
does not read anything.
Error 4051.
Also, how to make that it write to second column instead of placing delimiter ';'?
Thanks in advance.
