Dealer Greek Exposure

Full GEX analysis
How we calculate
Dealer exposure is computed from end-of-day options open interest and greeks across all listed strikes and expirations. We assume market makers hold the opposite side of public order flow. GEX, DEX, VEX, and CHEX are aggregated using the Black-Scholes model with dividend-adjusted forwards. Data updates after market close (~8:30 PM ET) based on OCC-reported OI.
What is GEX?

Net dealer gamma exposure. Positive = dealers buy dips/sell rallies (mean reversion). Negative = dealers amplify moves. Formula: GEX = Sum(gamma x OI x 100 x spot).

What is Gamma Flip?

Price where net GEX crosses zero. Above = positive gamma (supportive). Below = negative gamma (amplifying). Key intraday pivot level.

What is Call Wall?

Strike with highest call gamma. Dealers sell here on rallies, creating upside resistance. The upper bound of the dealer-defined trading range.

What is Put Wall?

Strike with highest put gamma. Dealers buy here on dips, creating downside support. The lower bound of the dealer-defined trading range.

Options Flow

How we calculate
Options flow aggregates open interest and volume across all listed strikes and expirations from OCC-reported data. Put/call ratios are computed from total contract counts. Active expirations count distinct expiry dates with meaningful OI. Updated after market close based on end-of-day OI reports.

C OI Concentration & Positioning

How concentrated open interest is across strikes - high concentration means a few key levels dominate hedging flows.

Volatility Surface

Full vol surface
How we calculate
The volatility surface is calibrated using the SVI (Stochastic Volatility Inspired) parameterisation fitted to mid-market option prices across all listed strikes and expirations. The 50×50 grid interpolates across log-moneyness and time-to-maturity. Skew metrics use 25-delta put and call IVs from the nearest monthly expiry. Updated after market close.

Put/Call Ratio

Logged in
How to read this
The put/call ratio compares put option activity to call option activity. A ratio above 1.0 means more puts than calls (bearish sentiment). Below 0.7 is typically considered bullish. The ratio by expiration shows where directional bets are concentrated, while the moneyness breakdown reveals whether traders are buying protection (OTM puts) or speculating on upside (OTM calls).

Live Options Flow

Alpha
How to read this
The tape buffer tracks every options print in the rolling in-memory window. Net volume = buy-classified contracts minus sell-classified contracts; positive = call/put demand pressure on the ask. Large blocks are prints ≥ 100 contracts, often institutional. Recent trades shows the latest tape with side classification (buy at ask / sell at bid / mid).

IV Edge Map

Growth
What is this?
The edge map shows the difference between SVI-fitted implied volatility and the ATM term structure IV at each strike/expiration point. Positive values (red) indicate options that are expensive relative to ATM - potential sell opportunities. Negative values (blue) indicate cheap options - potential buy opportunities. The larger the deviation, the stronger the signal.

Where the SVI-calibrated surface diverges from ATM term structure IV, options are potentially mispriced. Blue cells are cheap relative to ATM (buy edge). Red cells are rich (sell edge). The bigger the divergence, the stronger the signal.

C Volatility Skew by Expiry

How implied volatility varies across delta (10ΔP to 10ΔC) for each expiration. Steep put skew = expensive downside protection. Flat skew = balanced sentiment.

C Theta Decay by DTE

Net theta exposure aggregated by days-to-expiration bucket. Shows where time decay is concentrated - critical for premium sellers and income strategies.

C Bid-Ask Spread & Liquidity

Options market liquidity profile - ATM vs wing spreads and contract depth. Tighter spreads = better execution for traders.

VIX Term Structure

VIX index family across tenors - contango (rising curve) is normal; backwardation (inverted) signals near-term stress. The VIX futures basis shows the premium/discount of longer-dated vol expectations vs spot VIX.

C Volatility Risk Premium (VRP)

ALPHA

Is selling premium on C profitable right now? VRP measures the spread between implied and realized volatility - positive VRP means options are overpriced relative to actual moves. Combined with dealer positioning and directional decomposition, this tells you whether to sell, what structure to use, and how much to risk.

C Earnings & Expected Move

When C next reports earnings and the options-implied move priced into the front-month straddle, including the IV-crush kink in the volatility term structure.

C Key Options Levels

The full set of C dealer-hedging levels - gamma flip, max positive and negative gamma, call wall, put wall, and the 0DTE magnet - that act as support and resistance.

C Volatility Forecast

Conditional volatility forecasts for C from EWMA (RiskMetrics), HAR-RV (Corsi), and a maximum-likelihood GARCH(1,1) model, with mean-reversion half-life and long-run vol.

C Spot-Vol Correlation

The 20- and 60-day correlation between C spot returns and ATM-IV changes - the leverage effect. Equity indices run strongly negative: vol spikes when price falls.

C Dealer Positioning & Flow Risk

How C dealer gamma and delta exposure have shifted since the open from intraday options flow, and whether that flow is amplifying or dampening price moves.
