Spot $478.35 highlighted. The $540 strike holds the most open interest (the “wall”, 1,982). 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; 232 of these 387 calls were flat.

Ask about MLM
Why did the score rise from −34 to +19 this week?
It was mostly one day. The composite was −34.4 on 6 Oct, then rose to +68.1 on 8 Oct as the price moved from $482.27 to $479.01. It’s at +19.4 now.

Today’s +19.4 breaks down as −2.2 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.
