History

COHR, night by night.

Where the gamma levels, the net position and the priced move have sat on every recorded session. Readings are as captured that evening, not restated later.

10 Jun → 14 Sep
Walls over price

Call wall, put wall and zero-gamma per session, with the spot they were computed against. Walls step between listed strikes. Spot is the session close as CBOE's delayed feed settled it.

Net GEX · all expiries

Net gamma in $M across every listed expiry. The figures on the profile above are the nearest expiry only, so the two do not match. Dashed line marks zero.

Expected move · monthly
now 18 Sep

ATM-straddle implied move to the monthly expiry, % of spot. The line breaks at each roll to a new expiry — either side of a break prices a different contract. Rolled : 22 Jun, 20 Jul, 24 Aug.

implied move, % of spotroll to a new expiry

One reading per session, captured nightly after the close, 10 Jun → 14 Sep, over CBOE delayed (~15-min) chains, computed across the full listed chain. Gaps are weekends, holidays and sessions a capture missed; any reading can be absent on a session that was captured, and the series is broken rather than drawn through it.
