at 100 stop for 50 target your p/l ratio would be in the negative 2:1,so you would have to win 8 out out of 10 trades,but with a 100 stop for 300 target your break even is at 2.5 trades,and at a 50-50 point or better,you would totally kill!
When you backtest your stop triggers, don't be surprised that having a stop just about as wide as your profit target tests better than the tighter stop. Again, this is with the prototypical swing trading position holding period.
With 100pip stop 50 pip target you break even with 2 wins out of 3 trades. (100 loser, 50 winner, 50 winner = 2 out of 3) with 300pip target 100 pip stop you break even with 1 win out of 4 trades (300 winner 100 loser 100 loser 100 loser = 1 out of 4) The win rate is a function of stops. If you look at the win rate alone and say for example 1 out of 4 is easy, you will get killed like 95% get because they do not understand that it is the stops that cause the win rate. No more than 5 out of 100 traders understand what I wrote above.
