Hefajatur Rahman: but showing some error

ATR         = iATR(NULL, 0, ATR.Period, 1);

1. Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section, (bottom of the Root page?)
             General rules and best pratices of the Forum. - General - MQL5 programming forum
   Next time post in the correct place. The moderators will likely move this thread there soon.

2. You can't use periods in variable names since Build 600 and Higher. 2014.02.03
