Put/call = puts opened ÷ calls opened. Opened means contracts that gained open interest, study to settle. The gold mark is that same ratio over the prior five sessions (puts opened in the window ÷ calls opened in the window). Scale is log 0.5–2.0; 1.0 is an even split. Above 1.0 sits left (put-heavy).

vs ADV = contracts opened today ÷ the mean opened over those five sessions. Scale is log 0.5–2.0; 1.0 is the usual size.

Just under 60 percent of contracts opened on Wednesday were single stocks. That is where the book sat: not in the index complex, which printed 1.03 million, 7 percent of the day.

The exception on the figure is exchange-traded funds, the only class where puts outran calls — 2.39M against 2.68M. They have on 5 of the last 5 sessions. Stocks opened calls on all 5. That shape is the standing book.

Open interest change is settle minus study. Opened, in the paragraph, means contracts that gained open interest.

A VIX option prices off the future for its own expiry, not spot VIX. Implied vol is the median over a tight at-the-money band (delta 0.4–0.6) on the study tape, 13:30–20:51 UTC. VIX option IV is vol-of-vol; it prints near 150 percent, not 15.

A package (GLD, HYG, GDX) stays off the figure. Pre-earnings and earnings-day names are off the board (PDD, TJX, TGT, PURR).
