Des variables prédéfinies, pour le tick actuel, seraient mieux.



 
Il est extrêmement difficile d'appeler cela un self-shot.

Ahh, il y avait 1000 requêtes là ?
Je ne suis pas devant l'ordinateur pour vérifier.

fxsaber, et vraiment pourquoi y aurait-il 1000 requêtes pour le tick actuel ?

Anton, mais il a quand même glissé de 19 mcs.
En pourcentage du reste, c'est 850%.

Parfois, la mesure elle-même est lente, par exemple ::GetMicrosecondCount().

Un exemple simple :

GetLastError() ne fait que lire une cellule de mémoire dans le nat. En fait, le coût est nul.

Il convient de garder cela à l'esprit lors de l'évaluation de la mesure des actions ponctuelles par le biais de ce référentiel.

Une façon plus précise de mesurer :

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");

Merci, je vois.
Mais peut-être encore envisager d'introduire des variables prédéfinies?
La lecture d'une variable serait probablement plus rapide que l'appel d'une fonction et le remplissage d'une structure.
