Ahh, ¿había 1000 consultas allí?
Sólo que no está en el ordenador para comprobarlo.

fxsaber, y realmente ¿por qué habría 1000 consultas para el tick actual?

Anton, pero aún así se deslizó 19 mcs.
Como porcentaje del resto, es el 850%

A veces la propia medición es lenta, por ejemplo ::GetMicrosecondCount().

Un ejemplo sencillo:

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

void OnTick()
  {
   MqlTick Tick;

   for(int i=0;i<10;i++)

GetLastError() sólo está leyendo una celda de memoria en la nativa. En realidad, el coste es cero.

Si todavía tienes dudas, puedes hacerlo de esta manera:

#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);
  }

Esto es algo que hay que tener en cuenta a la hora de evaluar la medición de las acciones puntuales a través de este parámetro.

Una forma más precisa de medir:

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");
  }

Gracias, ya veo.
Pero, ¿aún así se puede considerar la introducción de variables predefinidas?
La lectura de una variable sería probablemente más rápida que llamar a una función y llenar una estructura.
