Hi Jim, I had a question about how to interpret and apply Zee's various look-back lengths, and he directed me to your seminal 2008 post, saying it was "exactly as you described it".

I read through your entire 2008 post, and I'm wondering if you could help me understand, as it's still not quite clear to me how Zee is approaching this.

When you referred to a look-back of say 120 days, does that mean you looked back 120 days to determine whether a 99-day high had been made in that 120 day period? Or, does it mean you looked to see whether a 120-day high had been made in the previous 99 days? (or possibly a 120-day high in the previous 120 days?)

I'm just not certain what the convention is so wanted to see if I could understand a little better.

(In another post, Elan wrote that the DBE signal is triggered 99 days after the most recent *252* day high. This seems to be another application, which I don't *think* matches what Zee is doing, but I'm honestly not sure.)
