Result of EMA

[amando]

Hello,

 

i try to run my EA on a 1H chart, but i calculate an EMA on daily basis,

so i use this code to get the daily EMA

 

double EMA500 = iMA(_Symbol,PERIOD_D1,50,0,MODE_EMA,PRICE_CLOSE);
double EMA501 = iMA(_Symbol,PERIOD_D1,50,1,MODE_EMA,PRICE_CLOSE);

  The interresting thing,

 

EMA500 result is 10

EMA501 result is 11

 

does anyone have an idea whats wrong?

Did you try to read the documentation ?

Returned value

Returns the handle of a specified technical indicator,  in case of failure returns INVALID_HANDLE. The computer memory can be freed from an indicator that is no more utilized, using the IndicatorRelease() function, to which the indicator handle is passed.

See this article https://www.mql5.com/en/articles/31

what does this means exactly?

im not a professional coder

 

how i get right values for iMA? in general i see its an integer, so i cant get double values.

 

but how i can handle the function right?

when i want to use this code from the MovingAvarege.mqh

 

double ExponentialMA(const int position,const int period,const double prev_value,const double &price[])
  {
//---
   double result=0.0;
//--- calculate value
   if(period>0)
     {
      double pr=2.0/(period+1.0);
      result=price[position]*pr+prev_value*(1-pr);
     }
//---
   return(result);
  }

 

what its meaning with

const int position: ??

const int period: is this Period_D1 and others ???

const double prev_value: ??

const double &price[]: is this PRICE_CLOSE ????
