Do you see any of these?
You don't do you? Then it is NOT an indicator.
The code is from documentation:

Hello,
I am new to MT4 and MQL4. I tried to run an EA as an Indicator and I receive the message "2013.01.28 19:14:56 Expert 'AAAA' is not custom indicator and will be removed". My question is how can be distinguished in code between the two ? At the first look I see no difference in coding.... out of author's comment: "this is an indicator/expert advisor".
Thanks in advance!
