EDIT: Forget about the editing, it'll be easier to make a new easy EA. I need something which adds a SL to each opened trade automatically and considers the spread. If SL worth is 10 pips and real spread 2 pips, it will create a SL of 12 pips.
Compared to routine halt loss EAs, the Bid/Ask values need to be switched, to add the spread to the SL.
For market orders it'd be ASK price(BUY button) /PLUS/ SL value.
For buy orders it'd be BID price(SELL button) - /MINUS/ SL value.
