imjohn,
How did you determine that your stop loss and and profit target will always be 1.5 : 1 (reward to risk)? Was this determined via back testing or just strictly personal risk and reward setting you chose for comfort, etc?
Stop is based on size of signal bar. Fluctuates trade-to-trade as sig bars vary in size. However, over 1000s of trades, averages are achieved. Target is simply the stop x 1.5.
Why 1.5x - I recorded thousands of sig occurrences on different time frames, different instruments, in different market conditions. Calculated how far the price traveled beyond my entry to determine potential targets. Tested out 1:1, 1.25:1, 1.5:1, 2:1, 3:1, etc. also tested various breakeven scenarios.. Found several profitable combinations, but 1.5:1 felt easiest to execute and drawdowns are easy to manage.
