Also, check this code which is suitable for arbitrary time frames (detected with the first price quote): #property strict void OnStart() { datetime seconds = _Period * 60; // state any amount in seconds datetime t_last_recorded = 0; // for demonstration sake while(!IsStopped()) { RefreshRates(); datetime t = TimeCurrent(); // time of last known quote datetime t_normalized = t / seconds * seconds; if(t_normalized > t_last_recorded) { // new bar printf("new bar!"); t_last_recorded = t_normalized; } Sleep(1); } }

{quote} Thanks, but I think OnTick is for EAs only, no?

void OnStart()
{
    while(!NewBar(PERIOD_CURRENT)) sleep(1000);
    // your code
}
