Activity-weighted call-put ratio for options regime context

Sentiment as a construction problem

The archive does not treat options sentiment as a ready-made headline. It first orients the scale as calls over puts, then asks what the tape is doing to open interest, then forms a multi-day figure that can sit as market context.

Scale orientation comes before premium-positioning, and premium-positioning comes before any contrary use of the finished reading.

The scale as calls over puts

A call-put-ratio measures calls against puts so that higher readings mark relatively heavier call activity and lower readings mark relatively heavier put activity.

Higher readings are mapped to greater call enthusiasm and, under a contrary reading, greater caution. Lower readings are mapped to pessimism and lower caution. That polarity is a construction choice. It is not yet a statement about whether new premium is being opened.

The option-writer as the other side

Selling a call or put to open is treated as the opposite directional statement from buying that same option. Clustered writing is therefore grouped with other contrary crowd behavior.

The option-writer belongs inside premium-positioning, the mix of newly written versus newly purchased option premium inferred from joint changes in volume and open interest.

What a single session cannot isolate

A single day's options volume and open-interest change cannot isolate which opening and closing long-short combinations produced the observed tape.

The construction does not claim to recover each long and short. It asks a coarser question about how much of the tape looks like new commitment rather than turnover of old positions.

Volume scaled by open interest

Volume-to-open-interest is session volume scaled by existing open interest, used to judge how much of the tape is new commitment versus turnover of old positions.

The sentiment composite is constructed as the call volume-to-open-interest ratio divided by the put volume-to-open-interest ratio. The call-over-put orientation stays in place. The open-interest scaling is what lets premium-positioning enter the same figure.

When volume and the composite disagree

In one gold-futures session a conventional call-put volume ratio near 1.03 coincided with a volume-to-open-interest composite of 0.49 after call open interest expanded more than put open interest on roughly similar volume.

The two readings can part ways when new call commitment dominates a tape that looks almost balanced on volume alone.

An activity-weighted window

An activity-weighted-window forms the multi-day ratio from summed call and put volume and summed open interest. High-activity sessions then receive more weight than quiet sessions that can distort a simple average of daily ratios.

The composite near an intermediate high

At a described intermediate high the composite is said to rise when a late burst of call buying lifts call volume while call open interest stays flat or falls, and put open interest grows slowly relative to put volume.

Editorial interpretation: that pattern reads as recycled call premium with relatively heavier new put commitment, not as confirmation that the crowd's late call buying is fresh opening demand.

Extremes that persist for weeks

Across equity-index, bond, Eurodollar, and gold examples, 10-day composite readings of 1.60 or higher were discussed as top-side extremes and readings of 0.70 or lower as low-side extremes.

Sentiment extremes are described as able to persist for weeks and to neutralize with time as well as with price, so a purely mechanical reading of the composite is treated as incomplete.

A slow contrary overlay

Editorial interpretation: the finished composite is a contrarian-overlay. Clustered options commitment is held as market-regime context rather than as confirmation of the crowd's stated direction.

That is why the reading belongs around a single trade on a weeks-to-months horizon. It is not rebuilt here as a same-day entry, exit, or abstention rule.
