Hi, I am trying to convert the ATR Pips that I used in MQL4 to the MQL5 language. So far there were no error already on compilation but their is no plot that is being shown when being attached to the MetaTrader. Any help with the code will be greatly appreciated.

There are a lot of things to go into, but if you modify the way you calculate ATR, you might be a little closer to the goal.

https://www.mql5.com/en/docs/indicators/iatr

The important part of the linked sample program is the following.

handle=iATR(name,period,atr_period);

CopyBuffer(ind_handle,0,0,amount,values)

double … percentSL * (iATR(Symbol(),PERIOD_CURRENT,periods)));

Perhaps you should read the manual, especially the examples.

      How To Interpret Answers.
         RTFM and STFW: How To Tell You've Seriously Screwed Up.

They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick (after the indicator has updated its buffers), you use the handle, shift and count to get the data.
