CIATR

Hello,


I tried to use for the ATR calculation the include files, 

but I always get Empty Value out


here the script

#include <Indicators\Indicator.mqh>      CIndicator _indi; #include <Indicators\Oscilators.mqh>     CiATR atr; void OnStart()   {    atr.Create(_Symbol,PERIOD_CURRENT,14);       Print(atr.Main(0));      }

is there something wrong?

Create(string,ENUM_TIMEFRAMES,int) - CiATR - Oscillators - Indicators - Standard Library - MQL5 Reference - Reference on algorithmic/automated trading language for MetaTrader 5

ok,

now I found it out


#include <Indicators\Oscilators.mqh>     CiATR atr; void OnStart()   { //---    //atr = new CiATR;       atr.Create(_Symbol,PERIOD_CURRENT,14);    atr.Refresh(-1);      Print(atr.Main(0));   }

but I don't know, why I have to refresh it


and is there a way to deinitialiszize?

Maybe it is  
atr.Destroy();

But i didn't test it so its best if you looked into the code it must be there.

Also you could use a fast timer.

atr.FullRelease(true);
releases the handle to the indicator. 

Nowhere in the class hierarchy of which CiATR is a member, does the Destroy() method exist.

More info can be found in the MT5 docs on CiATR. From there, you can navigate through the class hierarchy and look into the available methods.
