Options Positioning

Read where the options market is positioned.

Behind every chart sits an options book that shapes how price moves. StratosHedge organizes that book into research context — dealer gamma exposure, the call and put walls, the gamma flip, open-interest flow, and the shape of implied volatility — so you can study how positioning is leaning before you frame a thesis.

Key concepts

The vocabulary of options positioning.

A plain-language primer on the terms you will see across the workspace. This is educational background on how the options market works — not a recommendation, a prediction, or a description of a live scanner.

Options Flow
The stream of options being bought and sold across strikes and expirations. Studied in aggregate, flow shows where traders are building, rolling, and closing positions — useful as context for how the market is leaning, never as proof of intent.
Dealer Gamma Exposure (GEX)
An estimate of how dealers and market makers who are short options must hedge as the underlying moves. Net positive gamma tends to dampen volatility as hedging leans against the move; net negative gamma tends to amplify it as hedging chases price.
Call Wall
A strike above the current price with an outsized concentration of call open interest and dealer gamma. Hedging flows around it can behave like resistance — a reference level, not a guarantee, that can shift as positioning changes.
Put Wall
The mirror image below price: a strike thick with put open interest and dealer gamma where hedging can behave like support. Like the call wall, it is a positioning-derived level that moves as open interest builds, decays, or rolls.
Gamma Flip
The price region where estimated net dealer gamma crosses between positive and negative. Above it, hedging often stabilizes price; below it, hedging can accelerate moves. It marks a change in regime, not a fixed line.
Open Interest (OI)
The number of options contracts that remain open at a given strike and expiration. Tracking how open interest builds and unwinds over time is the foundation for reading walls, positioning, and flow.
Implied Volatility (IV)
The volatility priced into an option, reflecting the market's expectation of future movement. Comparing implied volatility across expirations — the term structure — shows how the market is pricing near-term versus longer-dated risk.
Volatility Skew
The way implied volatility varies across strikes for the same expiration. A steep downside skew, for instance, signals that the market is paying up for protection — a read on how risk is being priced across the chain.
Unusual Options Activity
A concept, offered here purely as education: options trades that look large or aggressive relative to what is normal for a contract — volume far above existing open interest, prints lifting the ask, or sudden interest in far-dated or far-out-of-the-money strikes. It can reflect hedging, spreads, or rolls as easily as a directional bet, so the intent behind a print is rarely knowable from the tape. StratosHedge does not run a live unusual-activity, sweeps, or block-print scanner; it teaches the concept and shows the positioning context around it.
How StratosHedge organizes it

Positioning, structured for research.

Each view is built from structured, third-party options data and price-aligned to the chart — so positioning sits next to the levels you actually study.

Net GEX / DEX / VEX / TEX by Strike

See estimated net dealer gamma, delta, vanna and charm exposure mapped strike by strike, updating in real time. The shape of the curve shows where hedging concentrates and where the book thins out.

Positioning Heatmap & 3D Surface

Read exposure across strikes and expirations at a glance in a positioning heatmap, then rotate a 3D surface to study how the book is shaped through time — where gamma stacks up and where it falls away.

IV Term Structure & Skew

Compare implied volatility across expirations to see how near-term and longer-dated risk are priced, and read the skew across strikes to see where the market is paying up for upside or protection.

Open-Interest Flow

Track how open interest builds and unwinds across strikes over time — the foundation beneath the walls and the gamma flip — so you can see positioning forming, not just where it stands today.

Alerts at the Walls & Gamma Flip

Set price and regime alerts at the call wall, put wall and gamma flip, and let StratosHedge notify you when price approaches the levels you care about — so you watch the chart on your terms, not constantly.

Options risk disclaimer. Options involve risk and are not suitable for all investors. Options flow and unusual activity should be used as research context, not as standalone trade signals. Positioning estimates — including dealer gamma exposure, the walls, and the gamma flip — are derived from third-party data and modeling assumptions that may be delayed, incomplete, or inaccurate, and they can change quickly as open interest builds, decays, or rolls. No level on this page is a recommendation, a price prediction, or a guarantee of how the market will behave. StratosHedge is a research platform, not an advisory service, and nothing here is financial, investment, tax, or legal advice. You are responsible for your own investment decisions.
FAQ

Common questions.

What is unusual options activity?

Unusual options activity is a concept, not a guarantee: it describes options trades that look large or aggressive relative to what is normal for a given contract — for example, volume that dwarfs the existing open interest, prints that hit the ask quickly, or sudden interest in far-dated or far-out-of-the-money strikes. It can reflect hedging, spreads, rolls, or institutional positioning as easily as a directional bet, so the identity and intent behind a print are rarely knowable from the tape alone. StratosHedge teaches the concept and shows the open-interest and positioning context around it; it does not operate a live unusual-activity, sweeps, or block-print scanner.

What is dealer gamma exposure (GEX)?

Dealer gamma exposure (GEX) is an estimate of how the dealers and market makers who are short options must hedge as the underlying price moves. When net dealer gamma is positive, hedging tends to lean against price moves and can dampen volatility; when it is negative, hedging tends to chase price and can amplify volatility. StratosHedge estimates net GEX (alongside DEX, VEX and TEX) by strike from open-interest and positioning data, price-aligned to the chart, as research context rather than a trade signal.

What are call and put walls?

A call wall is a strike with an unusually large concentration of call open interest and dealer gamma above the current price, where hedging flows can act as resistance; a put wall is the equivalent concentration below price, where hedging can act as support. These levels are reference points derived from positioning, not certainties — they can shift as open interest builds, decays, or rolls, especially around expiration. StratosHedge highlights the prevailing call wall, put wall and gamma flip, price-aligned to the chart.

Is options flow a buy or sell signal?

No. Options flow and unusual activity are research context, not standalone buy or sell signals. A single print or positioning level says nothing about who traded it, why, or what the rest of their book looks like, and walls and the gamma flip can move as positioning changes. StratosHedge presents this data to help frame analysis and risk; it does not tell you to buy or sell, and it is not financial advice. You are responsible for your own decisions.
