Here are the results from the formula below the chart. I ran the afl
two times. Once with positionscore using RSW and once using RSI. I
think your suggestion did improve results . I'll have to experiment
with subtracting for shorter time periods.

exact code (sorry), but I think you will find that negatively
applying the return for the last few days (weeks?) to this formula
will dramatically help a short-term system. In other words, add up
the returns like you are already doing and then subtract the returns
for the most recent period. This helps to buy stocks that have been
rising but are experiencing a pull-back.
