This experiment shows importance of knowing what is the average price swing we get in a given period. As shown by the backtest, if we keep target as 30 points, it is showing a loss because the period is sideways and it is giving very few 30-35 points price swings.Most swings are 10-15 points and hence if we keep 10-15 points profit target, we get many profitable trades and the performance becomes positive.
just my 2 cents....
