New bar arrived

[Essam Daoud]

Hi

mql5 EA

Will this code do well in checking if a new bar arrives?

Thanks

datetime currBarTime;

int OnInit() {
   currBarTime = SeriesInfoInteger(_Symbol, _Period, SERIES_LASTBAR_DATE);

}

void OnTick()
  {
    if (currBarTime != SeriesInfoInteger(_Symbol, _Period, SERIES_LASTBAR_DATE)) {
      // NEW BAR ARRIVED
    // DO STUFF
    }

No, it won't.

No, it won't.

Why? is it because SERIES_LASTBAR_DATE gives error sometimes? is so, what about this?

static datetime prevTime=0;
datetime lastTime[1];

OnTick(){

   if (CopyTime(_Symbol,_Period,0,1,lastTime)==1 && prevTime!=lastTime[0])
   {
      prevTime=lastTime[0];
    
      // ...new bar arrived, do stuff
   }
}
