Need help! Can't solve the problem, I'm hitting hardware limitations - page 21

Maybe milliseconds? On Windows-based OS in microseconds, the measurement just can't be done...

Sorry, just because you don't know how doesn't mean it's not possible:

The code Yurich uses, even in the terminal:

#import "kernel32.dll"
bool QueryPerformanceCounter(ulong &ticks);
bool QueryPerformanceFrequency(ulong &freq);
#import
//---
void OnStart()
{
   ulong t1, t2, st;
   QueryPerformanceFrequency(st);
   if(st>1000)
   {
      st=(ulong)1 e9/st;
      QueryPerformanceCounter(t1);
      Sleep(20);
      QueryPerformanceCounter(t2);
      Print("Tик таймера=",st," нс. // Sleep(20) = ",(t2-t1)*st," нс.");
   }else Print("Таймер высокого разрешения не поддерживается");
}

I'm not understating the abilities and capabilities of the terminal, but

when a couple of years ago I needed to extract data from a 1.21Gb file, with 21,345,728(!) lines,

Try again. In two years, the MQL4 (if done in it) language has been completely rewritten and the file operation completely rewritten.

The search time was 35-45 MICROSECUNDS according to the method I mentioned ,

Which method exactly?

The method of preparing the data.

In my case, it looked like this:

In your case you just take the MT5 x64 and read everything into memory in one piece. Then a quick one-pass scan to the right edges to plot the offsets.

In 2014, a file of some gig is not going to scare anyone.

Thanks, but I don't have a problem, komposter has a problem.

I told you how I solved it before (only once, no more needed).

P/S I can't even find my source code in the archive to give it to komposter

as an example.

Thanks, really didn't know. I'll have a look at that clock the other day.
