I am trying to create original EA with MQL5, but iCustom function returns always 10.0.

Code :

  double MA1 = iCustom("USDJPY",PERIOD_CURRENT,"Examples\\Custom Moving Average");

                 Alert(MA1);


If I delete Custom Moving Average.ex5,iCustom always returns value of -1.0.

so, Custom Moving Average.ex5 seems to be read correctly.

iCustom uses an integer and returns the handle for processing not an indicator value, have a look here

In MQL5, the indicator handle must be CREATED ONCE (in OnInit), and then (to obtain data) use CopyBuffer.

Example: iCustom
