Spot $4.63 highlighted. The $10 strike holds the most open interest (the “wall”, 102,769). 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; 300 of these 835 calls were flat.

Ask about QS
Why did the score drop from +67 to +43 this week?
It was mostly one day. The composite was +67.3 on 30 Sep, then fell to +36.9 on 1 Oct as the price moved from $4.91 to $4.65. It’s at +43.0 now.

Today’s +43.0 breaks down as +21.4 from volume and +21.6 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.
