Spot $84.12 highlighted. The $90 strike holds the most open interest (the “wall”, 3,822). Near-dated expiry in the mix, so OI is noisier.

One rule everywhere: a move of 0.05% or less is flat, and flat is not a hit. That is the same rule Proof uses; 178 of these 385 calls were flat.

Ask about EW
Why did the score rise from −37 to +47 this week?
It moved over several days. The composite was +14.2 on 3 Oct, then rose to +46.8 on 4 Oct as the price moved from $85.15 to $85.15. It’s at +46.5 now.

Today’s +46.5 breaks down as +31.9 from volume and +14.6 from open interest. I can’t split past days the same way: the stored history keeps call/put volume but not open interest for past days.
