Dead -
I use the scans extensively, and they do a pretty good job, but not perfect. There're still a few hours of work after the scan pulls (sometimes you'll get 300 stocks in the output - and yes, I look at them all!). Anyway, it's up to you how you want to run them. I've played with scans which will show me the recent 5/10 WMA crosses, as well as 10/20 dma crosses (or the 5/10 dma - whatever you want). For me, the best luck I've had is to scan for the longer term trend, then look at the current chart and look for an entry point.
Here's how the scan is written for the following conditions: Show all stocks whose 10 day moving average was less than the 20 dma 3 days ago, but who's 10 day moving average is currently greater than the 20 dma. (I call this my "Wize Scan.")
SMA Close 10, 3 days ago < SMA Close 20 3 days ago
SMA Close 10, 0 days ago > SMA Close 20 0 days ago
