Getting an EMA value for the MACD

[Tomisin Osasona]

can anyone help me with this bit of coding...

From what i understand... i can use the  ExponentialMAOnBuffer() but im not so clear as to how

I really don't understand what you want or need. The link of ExponentialMAOnBuffer() points to MathExp(value) which calculate e^value.

But the MACD is the difference of two ema and the ema of that difference.

You can find the code of the MACD already on your pc here:  ...\MQL5\Indicators\Examples\MACD.mq5.

BTW an ema is simple to calculate it yourself: newEma =  ((newValue-prvEma)*c + prvEma) ; and c = 2/(n+1) with n being the periods on the moving average.

To get that values on any indicator use iCustom() - there is an example.

Im trying to calculate for an EMA signal line... even if i cant get the line, just the values would do

i check the MACD code and i found this

/---
   int limit;
   if(prev_calculated==0)
      limit=0;
   else limit=prev_calculated-1;
//--- calculate MACD
   for(int i=limit;i<rates_total && !IsStopped();i++)
      ExtMacdBuffer[i]=ExtFastMaBuffer[i]-ExtSlowMaBuffer[i];
//--- calculate Signal
   SimpleMAOnBuffer(rates_total,prev_calculated,0,InpSignalSMA,ExtMacdBuffer,ExtSignalBuffer);
//--- OnCalculate done. Return new prev_calculated.
   return(rates_total);

would it just do the change the last line of coding

//--- calculate Signal
   ExponentialMAOnBuffer(rates_total,prev_calculated,1,InpSignalSMA,ExtMacdBuffer,ExtSignalBuffer);
//--- OnCalculate done. Return new prev_calculated.
   return(rates_total);
