What is CLDX gamma exposure (GEX) today?

CLDX gamma exposure (GEX) measures total dealer gamma across all strikes and expirations. Positive GEX means dealers dampen moves (buy dips, sell rips); negative GEX means dealers amplify moves. Live CLDX GEX, dealer regime, and the gamma flip level are on this page.

Where is the CLDX gamma flip, call wall, and put wall?

Current CLDX key levels: call wall at $35.00, put wall at $25.00. The call wall acts as resistance from dealer short-call hedging, the put wall as support from dealer short-put hedging, and the gamma flip marks where dealer hedging shifts from stabilising to destabilising.

What is Gamma Exposure (GEX)?

Gamma Exposure (GEX) measures the total gamma held by options market makers across all strikes and expirations. When dealers are long gamma (positive GEX), they buy dips and sell rips, dampening volatility. When short gamma (negative GEX), they amplify moves in both directions. The gamma flip level marks where positioning shifts from stabilising to destabilising.

What is Volatility Risk Premium (VRP)?

The Volatility Risk Premium is the difference between implied volatility (what options price in) and realised volatility (what actually happens). A positive VRP means options are expensive relative to actual moves - favorable for premium sellers. A negative VRP means the stock is moving more than options predict.

What is Implied Volatility (IV)?

Implied Volatility is the market's forecast of how much a stock will move, expressed as an annualised percentage. ATM IV reflects consensus expectations. The IV term structure shows how expectations change across time - contango (rising) is normal, while backwardation (inverted) signals a near-term event.

What is Options Skew?

Options skew measures how much more expensive out-of-the-money puts are compared to equidistant calls. The 25-delta skew compares 25-delta put IV to 25-delta call IV. Steep skew means the market is paying up for downside protection. Inverted skew can signal squeeze positioning or bullish sentiment.

What are DEX, VEX, and CHEX?

DEX (Delta Exposure) measures directional risk. VEX (Vanna Exposure) captures how dealer delta changes when volatility shifts. CHEX (Charm Exposure) shows how dealer delta evolves as time passes. Together, they reveal the full picture of dealer hedging flow.

What is a Volatility Surface?

The volatility surface maps implied volatility across strike price (moneyness) and time to expiration. Hot spots indicate where the market prices the most uncertainty. Traders use the surface to identify relative value - finding cheap or expensive options compared to the surrounding IV landscape.

What is an IV Edge Map?

The IV Edge Map shows the difference between SVI-calibrated implied volatility and ATM term structure IV at each strike and expiration. Positive values (red cells) indicate options that are expensive relative to ATM - potential sell opportunities for premium sellers. Negative values (blue cells) indicate cheap options - potential buy opportunities. The SVI model provides a smooth parametric fit to the volatility surface, so deviations from it highlight where market prices diverge from the model's fair value estimate.

0DTE (zero days to expiration) gamma measures the gamma exposure from options expiring on the same day. These options have the highest gamma per dollar invested and create the largest dealer hedging flows relative to their size. 0DTE options have become a dominant force in intraday market microstructure, and when 0DTE gamma is large, intraday price moves can be amplified by rapid dealer rebalancing.

What is Max Pain in Options?

Max Pain is the strike price where the total dollar value of outstanding put and call options would cause the greatest financial loss to option holders at expiration. It represents the price at which option sellers (writers) would pay out the least. While not a guaranteed magnet, many traders observe that stocks tend to gravitate toward max pain near expiration due to dealer hedging dynamics and the natural decay of out-of-the-money options.

What is the VIX Term Structure?

The VIX term structure shows expected volatility across different time horizons: VIX9D (9-day), VIX (30-day), VIX3M (3-month), and VIX6M (6-month). In normal markets, the curve slopes upward (contango) because longer-dated uncertainty is typically priced higher. When the curve inverts (backwardation), it signals acute near-term stress - the market expects more volatility now than in the future.

What is the CLDX options positioning narrative?

The CLDX options positioning narrative is a plain-English summary of dealer gamma exposure, key option levels (call wall, put wall, gamma flip), vanna and charm, and the resulting price-action bias. When dealers are short gamma they amplify price moves; when long gamma they dampen them. FlashAlpha regenerates the CLDX narrative each minute from live options data.

When does CLDX report earnings and what move is priced in?

The CLDX earnings section shows the next earnings date and session (before the open or after the close) alongside the options-implied move - the front-month straddle as a percentage of price. It also surfaces the term-structure kink, where front-expiry implied volatility is elevated for the event and collapses (IV crush) afterward. Only stocks that report earnings show this section; broad ETFs do not.

What are the key options levels for CLDX?

CLDX key options levels are the gamma flip, call wall, put wall, max positive gamma, max negative gamma, highest open-interest strike, and the 0DTE magnet. These are derived from dealer gamma positioning and act as support and resistance: the call wall caps upside, the put wall supports downside, the gamma flip marks the volatility-regime boundary, and the 0DTE magnet is where same-day expiry pins price.

What is CLDX's volatility forecast?

The CLDX volatility forecast combines three conditional models: EWMA (RiskMetrics, lambda 0.94), HAR-RV (Corsi heterogeneous autoregressive realized volatility), and a maximum-likelihood GARCH(1,1) with Student-t innovations. It reports a multi-horizon (1, 5, 21-day) forecast, the long-run mean volatility, and the mean-reversion half-life - how quickly volatility decays back toward its long-run level.

What is CLDX's spot-vol correlation?

CLDX spot-vol correlation is the 20- and 60-day Pearson correlation between spot log-returns and ATM implied-volatility changes - the leverage effect. Equity indices typically run strongly negative, meaning implied volatility spikes when price falls. A more negative correlation signals a stronger inverse spot/vol relationship and richer downside hedging demand.

How is CLDX dealer hedging flow shifting intraday?

The CLDX dealer positioning section compares settled dealer gamma and delta exposure to a live, simulation-aware estimate that incorporates intraday options flow. It classifies the net shift as amplifying (flow adds to moves), dampening (flow stabilises), neutral, or no-flow when every contract is still at its settled open interest before the session generates new positioning.

What is the CLDX dealer-regime strategy signal?

The CLDX strategy signal is a systematic dealer-regime decision envelope: it classifies the gamma regime, assigns a 0-100 score and a confidence, and lists best-fit option structures. It is a descriptive positioning read rather than trading advice, and it requires historical data coverage - symbols without historical coverage are flagged as not available rather than scored.

What is CLDX 0DTE options flow?

CLDX 0DTE options flow tracks same-day-expiry positioning using a live, simulation-aware model: net 0DTE gamma exposure, the intraday gamma flip and walls, a pin score, and dealer hedge-flow direction. 0DTE gamma is the largest intraday hedging driver relative to its size. The section is available for symbols with daily expiries (such as SPY, SPX, and QQQ) and pauses when the market is closed.

How liquid are CLDX options and where is open interest building?

The CLDX liquidity section scores per-expiry execution quality from 0-100 using ATM and open-interest-weighted bid-ask spreads, then flags the tightest and widest expiries. Alongside it, the open-interest change view surfaces the largest day-over-day OI shifts by strike - revealing where new positioning is building or unwinding across CLDX options.

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.

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).

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.
