How do you measure HFT? - General

fxsaber:

The reason for SymbolInfoTick's braking seems to be parallel handling.

> 100 ms for SymbolInfoTick execution. It's clear that the code is self-shot. But it shows the reason why slows down on usual Expert Advisors.

Predefined variables, for the current tick, would be better.

fxsaber 2020.10.20 07:35 #572

This is extremely difficult to call a self-shot.

#include <fxsaber\Benchmark\Benchmark.mqh> // https://www.mql5.com/ru/code/31279

void OnTick()
{
  MqlTick Tick;

  _B(SymbolInfoTick(_Symbol, Tick), 1000);
}

Result (inAmount = 15).

I'm stressed by this problem too.
HFT cannot be built with such delays.

Roman 2020.10.20 07:59 #574

fxsaber:

Wouldn't it be better to take the tiki out of the glass?
Didn't measure it ?

Z.u.s. or better yet FIX it ))

fxsaber 2020.10.20 08:16 #575

fxsaber:

It is better not to identify a new tick through the bars.

// Насколько бары отстают от тиков.

#include <fxsaber\Benchmark\Benchmark.mqh> // https://www.mql5.com/ru/code/31279

// Идентификация нового тика
bool IsNewTick_CopyRates()
{
  static MqlRates PrevRates = {0};
  MqlRates Rates[1];
    
  const bool Res = (::CopyRates(_Symbol, PERIOD_CURRENT, 0, 1, Rates) == 1) &&
//                   (_R(PrevRates) != Rates[0]); // TypeToBytes.mqh
                   ((Rates[0].time != PrevRates.time) ||
                    (Rates[0].tick_volume > PrevRates.tick_volume) ||
                    (Rates[0].close != PrevRates.close)); // Лишнее условие, но на всякий случай.
                   
  if (Res)
    PrevRates = Rates[0];
    
  return(Res);
}

void OnTick()
{
  _BV(while (!IsNewTick_CopyRates());, 100)

Ahh, was there 1000 queries there?
Just not at the computer to check.

fxsaber, and really why would there be 1000 queries for the current tick?

Anton, but it still slipped 19 mcs.
As a percentage of the rest, it's 850%

Sometimes the metering itself is slow, i.e. ::GetMicrosecondCount().

A simple example:

#include <Benchmark.mqh> // https://www.mql5.com/ru/code/31279

void OnTick()
  {
   MqlTick Tick;

   for(int i=0;i<10;i++)
      _B(GetLastError(), 1);

GetLastError() is just reading a memory cell in the nativa. Actually about zero cost.

If you still have doubts, you can do it this way:

#include <Benchmark.mqh> // https://www.mql5.com/ru/code/31279

void OnTick()
  {
   MqlTick Tick;

   int x=0;
   for(int i=0;i<10;i++)
      _B(x++, 1);
  }

This is something to keep in mind when evaluating the measurement of one-off actions through this benchmark.

A more accurate way of measuring:

void OnTick()
  {
   MqlTick Tick;

   ulong gstart=GetMicrosecondCount();

   int   count=10000;
   for(int i=0; i<count; i++)
     {
      SymbolInfoTick(_Symbol, Tick);
     }

   ulong gend=GetMicrosecondCount()-gstart;
   Print(count," iterations, total time ", DoubleToString(gend/1000.0,3)," ms; avr time: ",DoubleToString(gend/1000.0/count,3)," ms");
  }

Thanks, I see.
But maybe still consider introducing predefined variables?
Reading a variable would probably be faster than calling a function and filling a structure.
