Using a variable instead of explicitly stated the timeframe

[rcmw]

Hi,

I'm trying to assign 'PERIOD_M1' to a variable called 'timeframe' so I can change it once at the top but the below gives me error 'timeframe' - cannot convert enum. Any ideas?

void OnStart()

  {

//---

      int shift = 3;

      

      int File;

      int timeframe = PERIOD_M1;

      double open, close, high, low;

      File = FileOpen("OHLC.csv", FILE_CSV|FILE_WRITE);

      FileWrite(File,"Symbol","DateTime","Open","High","Low","Close");

       

      for(shift = 1; shift <= 100; shift++)

         {          

            open = iOpen(Symbol(),timeframe,shift);

            close = iClose(Symbol(),PERIOD_M1,shift);

            high = iHigh(Symbol(),PERIOD_M1,shift);

            low = iLow(Symbol(),PERIOD_M1,shift);  

            FileWrite(File, Symbol(),iTime(Symbol(),PERIOD_M1,shift),open,high,low,close);

            

         }

     

  }

Because timeframe is not of type INT,

is is of type ENUM_TIMEFRAMES 

You have to declare it this way:

int File;
ENUM_TIMEFRAMES MyTimeFrame;

MyTimeFrame = PERIOD_M1;

// And now you can change it like you would do to any variable.

another example:

ENUM_TIMEFRAMES timeframe = PERIOD_M1;

Perfect. Thank you very much sir!
