Trying to get the ATR value only. dont need to plot the indicator.

[Fernando Lima]

I developed a scalping trading system, and user a fixed ticks interval. 

Now I am trying to upgrade for a variable interval using ATR as reference. 

I am 100% blind on this.   

I´ve never used indicators before and don´t now how to do it. After some reading and search, my best try was:

 Thanks in advance. 

int ATR;


void OnInit() {
   
  ATR = iATR(_Symbol,PERIOD_M5,10);

}
  
void CheckATR() {

 ArraySetAsSeries(_atr, true);
  
 if( CopyBuffer(ATR,0,0,10,_atr) < 0) {Print("CopyBufferATR error =",GetLastError());}
  
 Print("the ATR is",_atr);

}

Bro,

you should always keep this inside the loop of section of your code OnStart(),OnTick or ... if you are going to use this value regularly.

the indicator is not important. the way of loading should be like below :

   double   ma[1];

   ExtHandle=iMA(_Symbol,_Period,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE); // can be placed inside OnInit as well
   if(CopyBuffer(ExtHandle,0,0,1,ma)!=1)
     {
      Print("CopyBuffer from iMA failed, no data");
      return;
     }

 or you have to use your function CheckATR() inside these loop. i hope i understood your need properly

int ATR; <---- double ATR[];


void OnInit() {
   
  ATR = iATR(_Symbol,PERIOD_M5,10);

}
  
void CheckATR() {

 ArraySetAsSeries(_atr, true);
  
 if( CopyBuffer(ATR,0,0,10,_atr) < 0) {Print("CopyBufferATR error =",GetLastError());}
  
 Print("the ATR is",_atr[0 to 9]);

}

I don´t need to check the value for every tick.  Just before opening new trader orders.  that´s whay I am using an function.  On my concepts, of course, i could be wrong.

thanks a lot.

Hi, thanks for the adjusments. 

I will try this way.

The stdlib has some pretty decent indicator wrappers which will make your life a whole lot easier. 

#include <Indicators\Indicators.mqh>
CiATR atr;
int OnInit()
{
   if(!atr.Create(_Symbol, PERIOD_M5, 10))
      return INIT_FAILED; 
   EventSetMillisecondTimer(1);
   return(INIT_SUCCEEDED);
}
void OnTick(){}
void OnTimer()
{
   atr.Refresh();
   if(atr.BarsCalculated() > 1){
      printf("ATR = %d points", 
         int(round(atr.Main(0) / _Point))
      );
      EventKillTimer();
   }
}

Hi Nicholi,

The stdlib fits perfectly.  Forsure the best way to implement what I needed; 

I did not use the OnTimer(), but works great for me.

thank you. 

Rgds.
