Thanks for the tip! Everything works as it should through CTrade. But it's still not nice that documented functions don't work as they should. (((( lost 4 hours yesterday trying to make my Expert Advisor work properly, and it is not some random library, but a documented native function. Very strange!
The most important thing is that everything worked as it should.
 
MetaDriver:

1) What exactly is the running version of the terminal already installed?

2) And what kind of processor do you have? Does it support SSE2 instructions?

Sorry, no reply for a long time, it's been a lot of work.

1. terminal version 4.0 ticket 509 is installed.

2. AMD Duron 1.2 GHz processor SSE instructions are supported SSE2 is not supported...

Sorry I haven't replied for a long time, it's been a busy time.

1. terminal version 4.0 ticket 509 is installed.

2. AMD Duron 1.2 GHz processor SSE instructions are supported SSE2 is not supported...

That's the point. New builds will not work without SSE2 instructions support. You need to upgrade your hardware.
 
Can you please tell me what this error of the Expert Advisor means? "2014.02.13 05:29:06.885 stop_gambling EURUSD,H1: Error setting Sell trailing stop: 130" ??
 

It says in the help:

STAT_RECOVERY_FACTOR

The recovery factor is the STAT_PROFIT/STAT_BALANCE_DDratio

Maybe the help should be corrected. Checked it. The recovery factor is calculated by means.

Pointer must be long.

look in MSDN, where handles or pointers are - add versions to long

I do this.

#import "kernel32.dll"
    int   CloseHandle(int hObject);
    int   CloseHandle(long hObject);
#import 

int   CloseHandle(long hObject)
{
  if (_Is64) return(kernel32:: CloseHandle(hObject));
  else return(kernel32:: CloseHandle((int)hObject));
}

в коде
::CloseHandle(h); // где h - long типа
 
Thanks, got it. I think I looked at the pointers, but I'd forgotten about the handles. And it breaks in such a way that you can't tell what's causing it...
