When looking at the historical charts. Specifically the SS 14,7 indicator, it shows gradient lines at 20% 50% and 80%. I wanted to flag a ticker when it goes through that line (20%) , but is under the 50% line. Now the scan does flag stocks, but when I look at their historical charts (SS 14,7) they are all over the place some way over 80, some in range and some under 20, so I'm confused as to what data is what ie scan results vs historical charts.
