Subject: Re: Chart: timing with Nas100 RS screen
if you can automate, apply the volume rule to the overlap strategy to determine whether to purchase, and then whether to sell mid-month, also.

The SPY>325day SMA timing signal for all purchases (or go to cash), then also the volume rule on buy date, generated 29.1% cagr post 1999.

If you also apply the volume rule mid-month to sell early (even if you have to get back in to the same stock the next month) it ups cagr to 31.8%
