Develop function iRSI multitimeframes

[servicioburo]

Hi everybody,

I try to develop in MQL5 a function multi iRSI, i wish send in a parameter the TimeFrame for calculate and this return the value. I have this example but i need write a function for each timeframe, it's not practique. How i develop just a function multi time frames?

Thanks :)

double CalculateRSIByPeriod_M1(int CalculateRSIAveragePeriod = 14)
   {
      double myRSIArray[];
      ArraySetAsSeries(myRSIArray, true);
      int myRSIDefinition = iRSI(_Symbol, PERIOD_M1, CalculateRSIAveragePeriod, PRICE_CLOSE);
      CopyBuffer(myRSIDefinition, 0, 1, 3, myRSIArray);
      double myRSIValue = NormalizeDouble(myRSIArray[0],2);
      return  myRSIValue; 
   }

double CalculateRSIByPeriod_M5(int CalculateRSIAveragePeriod = 14)
   {
      double myRSIArray[];
      ArraySetAsSeries(myRSIArray, true);
      int myRSIDefinition = iRSI(_Symbol, PERIOD_M5, CalculateRSIAveragePeriod, PRICE_CLOSE);
      CopyBuffer(myRSIDefinition, 0, 1, 3, myRSIArray);
      double myRSIValue = NormalizeDouble(myRSIArray[0],2);
      return  myRSIValue; 
   }

If somebody need the code is this:

input ENUM_TIMEFRAMES RSI_TimeFrame             = PERIOD_M15; // TimeFrame for RSI

double CalculateRSIByPeriod(ENUM_TIMEFRAMES Period_ = PERIOD_CURRENT, int CalculateRSIAveragePeriod = 14)
   {
      double      myRSIArray[];
      ArraySetAsSeries(myRSIArray, true);
      int         myRSIDefinition      = iRSI(_Symbol, Period_, CalculateRSIAveragePeriod, PRICE_CLOSE);
      CopyBuffer(myRSIDefinition, 0, 1, 3, myRSIArray);
      double      myRSIValue           = NormalizeDouble(myRSIArray[0],2);
      return      myRSIValue; 
   }

double RSIValue               = CalculateRSIByPeriod(RSI_TimeFrame, RSI_Period);

In MQL5, the indicator handle MUST BE CREATED ONCE - IN OnInit ().

You create indicator handles haphazardly and repeatedly. It is unacceptable. This is a gross mistake.

You need to do this: determine the parameters and timeframes of the RSI indicators - and create all indicators in OnInit. And only then, in your custom function, use CopyBuffer .
