Collected 16 Oct, 02:27 BSTThe shape of the options market
Read the chain at a glance.
191 of 328 unexpired retained contracts have positive, ordered quotes with a spread no wider than half their midpoint. This is a quote check, not a promise of execution.
Where are positions concentrated?
Darker cells mark more reported contracts. Select a cell, or use the arrow keys, to explore its value.
Up to 10 expiries and 16 displayed strikes, selected from the retained chain. Blank cells mean no observation; they are not zero. Large positions can be hedges or parts of spreads.
A closer look at sensitivity
Gamma, mapped.
Find the strikes and expiries where option sensitivity is concentrated.
Gamma needs a matched stock price and usable inputs.
This reading has no stock price matched to its observation. The activity and quoted-volatility charts below remain available.
How to read the map ยท coverage and assumptions
Colour shows size and side
In โCalls โ putsโ, green means the measured call sensitivity is larger; rose means the put sensitivity is larger. Combined sensitivity adds both sides. Long calls and long puts both have positive gamma.
These figures do not reveal dealer inventory, buying or selling, a price magnet, or a guaranteed support or resistance level.
A dated, standard-contract estimate
Dollar sensitivity = gamma ร open interest ร 100 shares ร stock priceยฒ ร 1%. Reported gamma is used when available; otherwise a European model uses checked quoted volatility with zero rate and dividends. Known non-standard contracts and same-day expiries are excluded. Unspecified contract sizes assume 100 shares.
Open interest and quotes can have different update times. Blank cells are unavailable, not zero.
Volatility, activity and trading costs
Three more ways to read the chain.
Where is uncertainty priced higher?
Annualised quoted volatility. Colour compares the available contracts; it does not show the chance of a move.
Does trading focus match open interest?
Each expiryโs share of reported volume and open interest. Compare the two bars, then check the counts.
How wide are the quotes?
Median spread as a percentage of the midpoint, including wide quotes. Lower means less distance between bid and ask.

Can the quotes support the analysis?
Quote coverage by expiry
Checked quotes versus other retained contracts. Missing, crossed, zero-bid and widely spread quotes are excluded from priced scenarios.
Turn a reading into questions
Three paths to watch.
The reading strengthens
Price and activity agree
- Price holds or improves while call-side concentration remains elevated.
- Participation is above the ticker's stored normal, which makes the read more noteworthy.
Price stays near its level
Time becomes more important
Compare the cost of waiting with the move already reflected in premiums. A quiet stock can still have expensive options.
Explore a range scenario โThe reading weakens
Check what stops agreeing
- Price weakens while call pressure fades or reverses toward puts.
- Options and the weekly trend are not yet giving the same message.
- Front-expiry volatility is rich, so the signal may be event-driven and vulnerable to volatility compression.

Same position. Different paths.

What moves this position?
Modelled sensitivity for the entire position at the reference price. Change an input and see how the balance changes.
Expiry profit or loss follows the entered legs. Earlier values use a European option model with constant volatility and the stated rate and dividend yield. US stock options can be exercised early; assignment, changing volatility and execution prices can change actual results.

Volume and open interest are contract counts. IV is annualised. A dash means the value was not supplied; zero is a reported value.
Options balance over time
Session history โSaved pressure readings
Dated readings using the same calculation version. Positive is call-heavy; negative is put-heavy.
A reading needs context
What has changed over time?
Volatility through saved sessions
Annualised reference IV. The available strikes and nearest expiry may change between readings; this is not a constant-maturity series.
Activity relative to outstanding positions
Session volume divided by open interest. A rising ratio means more turnover relative to outstanding contracts, not necessarily new positions.
Outcome record Completed observations only
Stock-price direction through expiry, using the first available weekly close on or just after expiry. These are not option-trade returns.
| Record | Followed direction | Always up | Always down | 95% interval |
|---|---|---|---|---|
| Earlier saved readings Too few independent outcomes to establish an edge. | 2 / 6 | 17% | 83% | 10โ70% |
Earlier saved readings are reviewed retrospectively, separately from readings recorded in advance. Overlapping periods are excluded. The comparison uses the same stocks and dates; costs and option execution are not tested.
Read the picture
Options, in plain sight.
01 Price is only part of the story
A call can lose value even when the stock rises. The rise may be too small, time may run out, or implied volatility may fall. Use the lab to hold price steady and change days or volatility.
Price movement+Time remaining+VolatilityโOption value
02 Volume is activity, not intent
Volume counts contracts traded during a session. Every transaction has a buyer and a seller. Call-heavy activity alone does not tell us who initiated the trade or whether it was part of a hedge.
BuyerโOne contract tradedโSeller
03 Open interest is an outstanding position
Open interest counts contracts still outstanding, usually reported after clearing. A busy session does not necessarily create new positions. A large concentration at a strike is a place to investigate, not a guaranteed support or resistance level.
04 A priced move has no direction
A near-money call and put can describe the cost of exposure to a move in either direction. The displayed range is a pricing reference. It is neither a price target nor a fixed probability interval.
Lower referenceโStock priceโUpper reference
05 A high IV needs a comparison
Implied volatility describes the movement reflected in option prices, expressed as an annualised percentage. Compare the same stock across expiries, strikes and dated history. A high value alone does not prove an option is expensive.
06 The spread is part of the cost
The bid is the quoted selling price; the ask is the quoted buying price. Their difference matters, especially on a position with several legs. A midpoint is an estimate, not an assured fill. Saved-quote playbooks buy at the ask and sell at the bid.
