Spot $1.09 highlighted. The $1.50 strike holds the most open interest (the “wall”, 9,135). 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; 221 of these 473 calls were flat.

Ask about CRDF
Why did the score drop from +100 to +88 this week?
It was mostly one day. The composite was +99.5 on 7 Oct, then fell to +87.4 on 8 Oct as the price moved from $1.13 to $1.09. It’s at +88.1 now.

Today’s +88.1 breaks down as +50.7 from volume and +37.4 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.
