Close Bar from a higher period

New comment
 

When I'm on an H4 chart, how do I determine when the bar has closed on a D1 chart?

Thanks in advance,

use TimeCurrent().
 
at opening new bar H4 Time[0] == iTime(Symbol (),PERIOD_D1,0);
 
deVries:
at opening new bar H4 Time[0] == iTime(Symbol (),PERIOD_D1,0);

That would work with most symbols, but only if the first H4 bar of the day is at midnight (broker time)

OK this can also

bool newday = false; 
if(iVolume(Symbol (),PERIOD_D1,0) < dayvolume)
    {
    newday = true;
    dayvolume = iVolume(Symbol (),PERIOD_D1,0);
    }
  else dayvolume = iVolume(Symbol (),PERIOD_D1,0);
      

when is this failing ??

You cannot, you can only know that a new bar has started.

If you meant what time does a new D1 bar start . . . well it starts at the first tick after midnight Broker time.

If you want to detect the first tick of the new D1 baar then that is easy . . . create a static local variable of a variable with global scope . . .

datetime D1Bar1Time = 0;         //  global scope variable

// or

static datetime D1Bar1Time = 0;  //  static local

then in start() . . .

if(D1Bar1Time == 0)
   D1Bar1Time = iTime(NULL, PERIOD_D1, 1);

if( iTime(NULL, PERIOD_D1, 1) > D1Bar1Time )
   {
   // we have a new D1 bar . . .
   
   iTime(NULL, PERIOD_D1, 1)
   }

Isn't the first H4 bar of a day always starting at midnight (broker time) ?

after a weekend or marketholiday the time of new dailybar will be different from h4 period while both can be a new bar sundaycandle
 
Ah ok in such a case. All brokers I use doesn't have Sunday candle. Thank you.
