Spot $178.98 highlighted. The $170 strike holds the most open interest (the “wall”, 3,188). 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; 1335 of these 1700 calls were flat.

Ask about AMT
Why did the score rise from −15 to +21 this week?
It moved over several days. The composite was −0.8 on 7 Oct, then rose to +18.7 on 8 Oct as the price moved from $162.20 to $166.18. It’s at +21.1 now.

Today’s +21.1 breaks down as +18.9 from volume and +2.2 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.
