the stop loss should be the worst case scenario, like let's say you enter and then the market heads straight for the stop, case in which you can't react in any way but take your loss.
however, the better you know your setup and what need to happen, the quicker you realize when the trade is not really working, the quicker you take your loss, which in most normal cases can even be 1/3 of your stop (risked amount), and only by doing that and having a reliable setup can put you in advantage (ie have an edge).
the key in trading is recognizing when the trade is not working and taking the smallest possible loss.... there is no other secret... When you do that, you can risk more than the classical 2% of your account. You can risk 10% and go for a 1:1. If you take your loss on average about 1/3 of your stop, you actually lose 3%, maybe less, but still take 10% wins or maybe more, depending on your gut...
