EA with sma's crossing back testing. SL and TP automatically generated

Hi there

I've created an EA involving opening and closing trades based on sma's crossing over.
I've not set up any stop losses or take profit because I'm just opening the next order as the other one closes and so on.
When I try to backtest meta trader automatically puts in a 30 pip stop loss and 30 pip take profit which I can't delete.

Anyone have any ideas??

Much appreciated
Katie
