For example if you have a 10,000$ account and your rule per trade is 5%. (using this trade as an example) it means you are going to lose $500 on this trade (not that i'd use 5% on this trade 1% tops). Your stop loss below point D is about 13 pips while stop loss Above D is 7 pips. 1. Stop loss 13 pips) means that you'd divide 500/13= 38.46$per pip x 20 (pips gain if target is met) which give you $769.23 in profit. Now with the other 7 pip stop loss 500/7 = 71.43 x 20 = $1428.57 which is almost twice as much.
there is a downside to this strategy. Having a larger stop loss gives more room for play, while a tighter stop loss can easily be triggered by high . but for this trade, i wouldn't worry so much since a move past the close with will most likely stop out both stops. but as always as a human being, i could be wrong. let see how it plays out.
