Spot $2.22 highlighted. The $2 strike holds the most open interest (the “wall”, 17,498). 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; 511 of these 1829 calls were flat.

Ask about OPEN
Why did the score rise from +64 to +67 this week?
It was mostly one day. The composite was +63.5 on 7 Oct, then rose to +70.9 on 8 Oct as the price moved from $2.44 to $2.27. It’s at +67.3 now.

Today’s +67.3 breaks down as +48.4 from volume and +18.8 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.
