UAsish,
based on your posts, i felt that you are fascinated by mechanical trading systems, i was also very confident about them but my interest had waned over the years. is it possible for you run the system using 1000 stocks over a period of 5 years and let me know the yearly appreciation of portfolio, don't worry about the starting capital, just buy when a buy signal is generated and sell when a sell signal is generated.
i did try to tweak buy and sell signals based on the observation i made using winning stocks, but unfortunately i could not filter the loosers out, so roughly 50% of loosing stocks also generate the signals thereby neutralising the portfolio's advantage
thanks
