Define timeframe as input in mql5 and initializing it

New comment
 

Hi. 

enum timeframe
  {
   M30 = PERIOD_M30,
   H1 = PERIOD_H1,
   H4 = PERIOD_H4,
   D1 = PERIOD_D1,
   W1 = PERIOD_W1,
   MN1 = PERIOD_MN1,
  };

input timeframe = PERIOD_H4;


int OnInit(){
   macdHandle = iMACD(_Symbol, PERIOD_H4, 12, 26, 9, PRICE_CLOSE);
}


I just migrate from mql4 to mql5 and I can't define timeframe as input and initializing it. 

Can anyone help me to do that?

Thank you so much.

  
input timeframe InpTF = H4;

No need to create a new enumeration.

The solution is the same in MQL4 and MQL5

input ENUM_TIMEFRAMES   timeframe = PERIOD_H4;  // Timeframe for MACD

int OnInit()
{
   macdHandle = iMACD(_Symbol, timeframe, 12, 26, 9, PRICE_CLOSE);
}
 
  1. Fernando Morales: No need to create a new enumeration.

    Unless you want to restrict the valid timeframes to just those listed.

  2. Why did you post your MT5 question in the MQL4 section, (bottom of the Root page)?

    Next time post in the correct place. The moderators will likely move this thread there soon.

  3.    macdHandle = iMACD(_Symbol, PERIOD_H4, 12, 26, 9, PRICE_CLOSE);
    If you want to pass timeframe to the MACD, cast it to a ENUM_TIMEFRAMES. That is why your original enumeration used PERIOD_… as values.
 

If you want to make an input of only your custom timeframes to just those listed.

You can use something like using a switch statement in OnInit Function.

ENUM_TIMEFRAMES TimeFrame = PERIOD_M5;
enum MY_TIMEFRAME {    
    Period_M1,    // 1 Minute (Default)
    Period_M5,    // 5 Minute
    Period_M15,   // 15 Minute
    Period_M30,   // 30 Minute
    Period_H1,    // 1 Hour
    Period_H4    // 4 Hour
};

input MY_TIMEFRAME InpTimeFrame = Period_M1;

int OnInit()
  {
  switch(InpTimeFrame)
    {
     case Period_M1:
       TimeFrame=PERIOD_M1;
       break;
     case Period_M5:
       TimeFrame=PERIOD_M5;
       break;  
     case Period_M15:
       TimeFrame=PERIOD_M15;
       break;  
     case Period_M30:
       TimeFrame=PERIOD_M30;
       break;
     case Period_H1:
       TimeFrame=PERIOD_H1;
       break;         
     default:
        TimeFrame=PERIOD_CURRENT;
       break;
    } 

return(INIT_SUCCEEDED);
}
