No way to refund in case you activated it.

I want to request refund for an indicator i bought. It's your mistake to think that you can get a refund when it isn't profitable. =4) { print(__function__+"("+string(__line__)+")"+": error "+string(getlasterror())+"
 

For future reference, you don't need to buy an EA in order to test it in the Strategy Tester, you can download the demo version and perform your tests.

This doesn't work for some utilities or trading panels, it applies to indicators and most trading expert advisors.
