Hi GD_.... Great approach !

But this is RRS ( Regression Slope) as opposed to SMA Change as defined and tested by Jim.
So its different - I am not value judging better/worse - but different. Because RRS ( 126d)
is proven as a Ranking metric through a lot of screens.

The main difference in my view - depending on how you have defined it would be the following
q's

(1) Did you just take the 180d SMA for last 2 weeks and calc the Slope - this would actually be very similar to Jim's
(2) While on the other hand - if you take the ACTUAL 180d Slope of the indices - that might take a while to turn over(slower but lesser whipsaws as is norm)- since it depends on the Regression fit.

(3) Jim's original definition ( and IIRC it was on the SP500) - is a 2 point check ie SMA180(0) - SMA180(10) <0. The smoothness comes from the SMA - which is fairly MT/LT and so it simply means - if there has been a LOT OF BAD DAYS LATELY - for it to go negative.

From an RRS standpoint .... it would take a LOT of Days for the entire observation cloud to have negative slope on 180d lookback

Hope this made sense!

best
