I like this scan a lot. This gives you some hot targets that are crossing from below over the 25 or 30. Some other software allow you to define it by crossing from below or crossing from above. Because you may want to find stocks that are really tanking and are crossing from above the 30 mark and heading lower. Or you could be looking for stocks that are crossing from below the 70 mark and really taking off to the over bought side. But that run can be pretty solid before it turns. Also the crossing from above the 70 usually indicates a turn down in the price. Great work.
Although looking at it, I do see Crossed Above which would have to indicate that it was crossing from below the 70 mark. So that should work just fine.
I used RSI crossing above 25 and 30 ...high % of 1-3 day movers. Several had significant moves for 10-12 days. I used several dates over the last year chosen at random.
i've already work with two different RSI length to find reversal (RSI(9) higher than RSI(14)) to help me choosing stocks along with other criterias and i remember it was not bad. I also saw someone using RSI "powerzone" where bullish stocks can drop to RSI(14) = 40 for support and bearish stocks can climb up to RSI(14) = 60 to resistance. I think i'll try to replicate the 2 differents RSI length with the back to back scan.
Unfortunately the RSI Cross scan is one of a few scans that's not available in the Back-to-Back Scan nor the Combo Scan. There's a technical implementation reason as well as it would require complicating the user interface to include 3 more entry fields for the RSI cross levels for each day.
