Thing you have to realise going in is there is no gaurantee when you place the order that there is a willing party on the opposite side.
If the price action moves away you cannot amend. It is also a day only order. There is no way it even comes close to levelling the playing field.

I use it with extreme caution the same way I analyse before placing a trade via ChiX for the same reasons.
Summer time is good and summer time is bad.
