 For some reason I started wondering if the Days Ago phrase was counting calendar days or trading days so I did a little test. I wrote a simple two line filter. I'll even make it clickable.
 
 
 
 
 I found that gives me the close from 7 trading days ago, not 7 calendar days. When I changed it to 5 days ago it showed me the closing price from one calendar week ago which is what I wanted. I'm annoyed because I never thought to ask this before. Now I'm wondering if I have to change other parts of some filters, like the comparative relative strength lines.
 
 Would this set {rs1, relative strength(SPY,20} be looking at 20 calendar days or 20 trading days?

 Days = trading days, not calendar days.

 So it's trading days for the line in question as well as the Days Ago phrase. Thanks. That's good to know.

 Same with a 10-day moving average, such as...
 
 Add column MA(10)
 It covers 10 “market” days.
 
 Or...
 
 Add column ROC(5)
 which covers 5 “market” days
 of performance % results.
