_Period not work in MQL5

[Hadi Ghoreishimedyseh]

Hello friends

It seems new version of MQL5 have problem to get the value of Period, I have tried both " Period()  ,  _Period "  But the out come is wrong

I write this simple code, and change time frame to check the result, But the out come is Wrong !!!

I use MQL5 version 3030

int OnInit()
  {

    Print(" result period : ",Period());

   return(INIT_SUCCEEDED);
  }

That's right, there are no mistakes. ENUM_TIMEFRAMES is an enumeration.

Thanks Vladimir.

But I want to get current chart Time frame value . The only way is Period(). But it do not show correct result. how can I get Current chart Time frame value ?

Period () shows exactly the current timeframe. There are no digits '1', '2' ... instead there are ENTRY ITEMS: 'PERIOD_M1', 'PERIOD_M2', 'PERIOD_M3' ...

   ENUM_TIMEFRAMES tf = ENUM_TIMEFRAMES(_Period);

2. Seyed Hadi Ghoreishimedyseh:   But the out come is wrong

   It does not “come out wrong.” It is not a “wrong value.” It is an enumeration; its value is irrelevant. Its value is not in minutes; use PeriodSeconds(tf)/60 if you want that.

Just create your own function like:

int eTF2minTF( const ENUM_TIMEFRAMES tf ) {
   switch(tf) {
      case PERIOD_CURRENT: return(0);
      case PERIOD_M1:  return(1);
      case PERIOD_M2:  return(2);
      case PERIOD_M3:  return(3);
      case PERIOD_M4:  return(4);      
      case PERIOD_M5:  return(5);
      case PERIOD_M6:  return(6);
      case PERIOD_M10: return(10);
      case PERIOD_M12: return(12);
      case PERIOD_M15: return(15);
      case PERIOD_M20: return(20);
      case PERIOD_M30: return(30);
      case PERIOD_H1:  return(60);
      case PERIOD_H2:  return(120);
      case PERIOD_H3:  return(180);
      case PERIOD_H4:  return(240);
      case PERIOD_H6:  return(360);
      case PERIOD_H8:  return(480);
      case PERIOD_H12: return(720);
      case PERIOD_D1:  return(1440);
      case PERIOD_W1:  return(10080);
      case PERIOD_MN1: return(43200);
   }
   return(-1);
}
int min = eTF2minTF(_Period);

Carl Schreiber #: Just create your own function like:

No need, use #define eTF2minTF(p) (PeriodSeconds(p)/60)

Sir,

is it possible to use higher TF for calculating in a specific timeframe?

for example : use M15 data on M1 TF.

Something Like This :

input ENUM_TIMEFRAMES    tf1             = 15;              // Time Frame (15)
ENUM_TIMEFRAMES(_Period) = tf1;

I Think I Should Use Barshift.

Right?
