May I ask, what is sq2sd.s?
I put it in the post: [SI Qtrly Surprise-Prior Qtr-Std. Dev.] :
Doh! Thank you!!!
I wouldn’t do this if I were in your place - that metric is not available till beginning of 2009 - so its completely skewed in a 12 year Bull run ie has no resiliency testing in bear markets.
Backtests are not just passage of time - they need to be representative of all possible conditions to be faced in future for it to be reliable

I think we have been in a bear market for a while, so it may be representative of a full cycle.

One of the last things Jim said before he left was that screens that are 5 deep are too prone to randomness. He thought that screens that are 40 deep have a much better chance of equaling their backtests.
