Have any of you tried to convert this into a scan of all stocks on a given index, etc.?

Also, what platforms support Wilson Relative Price Channel? It doesn't appear that StockCharts or ProRealTime do. It's intriguing, to say the least.

Sorry, not "scan" but "screen"; i.e., identifying those stocks that are crossing over into the upper territory, etc.

This is a custom indicator (not mine), that has not seen large scale adoption. However, the code is pretty simple and can easily be replicated in most screening platforms (at least any that are decent enough to give you the ability to write some code).

And to look for stocks within an index (e.g., the S&P 500) here on StockFetcher, just substitute the line "symlist(AAPL)" with "market is S&P 500".

OK, baby steps are being taken into the land of screening on SF. Where am I getting off in the weeds?

set{OB2, OB1 /100}

do not write symlist(). All you need to say is "market is S&P 500" on the first line (technically it can be on any line).

Ah. OK, thanks. If I add "within the last 1 day" I get this -- make sense?

Figured out the "Fetcher" command. I'm not liking the way some selections are hanging out in the upper zone, dip below, and then trigger. I'll add a moving average constraint to see if it shakes anybody out. (I realize I need to backtest these ideas.)

OK, that knocked out one stock. I'm going to say NRG and NI are more interesting than the rest, since they are just now breaking into the upper Wilson zone AND their moving average (200 day) is rising. Anyone have a problem with that logic? I'm sure I could add a "MA slope" constraint to the screener if I wanted to. I'd have to backtest to see if that actually improved results, though.

Thanks for the help.

I found it more interesting from looking at this filter that if the price falls under the NZL zone and then breaks up through it this seems like a pretty good by signal, not crossing the upper zone. So my buy would be three up days or so coming up through the lower zone. Hoping it will work it's way above the upper zone and when it crosses back down from above through the upper zone sell it.

If it crosses from below up through the lower zone for 2-3 days but it, and if it comes back down through the lower zone dump it. Study a bunch of charts and tell me if you see the same thing. I've bought one ETF as a test.
