I am one of the lurkers who have been monitoring Spytrader's posts for a couple of months while undergoing the requisite training (reviewing Journals I and II). I stumbled upon the thread while testing scripts on the Wealth-Lab site.
That said, I'd like to add a possible corollary to the methodology.
In monitoring the hot list this morning I noticed that BOOM's volume really began to head north yesterday in the final hour of trading. In effect, if the last hour of trading shows increased volume and the beginning of the current day's trading shows the same level of increasing volume (all other indicators being positive) then I'd suggest that the lower band was hit just prior to the observed "boom" in BOOM this morning.
Using that calculus, I dove into the buy fifteen minutes ahead of the stampede.
My suggestion is that we begin to observe the last hour of the previous day to see if the rules might be modified to include that action in the buy determination.
