SPTI Options Analytics Dashboard
SPTI snapshot: ATM IV 9.9%. HV20 4.9%.
This page provides real-time options analytics for SPTI, including:
- Implied Volatility (IV) - ATM IV, 20-day and 60-day historical volatility, IV percentile rank, and volatility risk premium (VRP).
- Gamma Exposure (GEX) - Net dealer gamma exposure, top strikes by gamma notional, call wall, put wall, and gamma flip level. Indicates whether dealers are long or short gamma and the resulting regime (mean-reverting vs. trend-amplifying).
- Dealer Positioning - DEX (delta exposure), VEX (vanna exposure), and CHEX (charm exposure) show how dealer hedging flows respond to price moves, volatility shifts, and time decay.
- Volatility Surface - SVI-calibrated IV heatmap across strikes and expirations, 25-delta skew, smile ratio, and term structure.
- Options Flow - Put/call ratio, total volume and open interest, and net premium flow direction.
- Macro Context - VIX level, Fed Funds rate, and 10Y yield for broader market context.
SPTI Implied Volatility & Term Structure
Track SPTI ATM implied volatility, 20-day and 60-day historical (realized) volatility, IV percentile rank, and the volatility risk premium (VRP). The IV term structure shows how implied volatility changes across expirations - contango (upward sloping) is the normal state; backwardation signals near-term event risk such as earnings or macro catalysts. IV-RV spreads reveal whether SPTI options are cheap or expensive relative to actual realized moves.
SPTI Gamma Exposure (GEX) & Key Levels
SPTI net dealer gamma exposure quantifies whether market makers are long or short gamma. In a positive gamma regime, dealers buy dips and sell rips, dampening volatility. In negative gamma, dealers amplify moves. The call wall is the strike with the highest call gamma - it acts as resistance. The put wall is the highest put gamma strike - it acts as support. The gamma flip level marks where dealer positioning switches from stabilizing to destabilizing. Top strikes by gamma notional show where the largest hedging flows concentrate.
SPTI Dealer Greek Exposure - DEX, VEX, CHEX
Beyond gamma, dealer positioning includes delta exposure (DEX), vanna exposure (VEX), and charm exposure (CHEX). DEX measures directional risk from dealer hedging. VEX captures how dealer delta shifts when volatility changes - a large VEX means volatility moves trigger significant hedging flows. CHEX shows how time decay alters dealer delta, creating predictable end-of-day and end-of-week flows. Together these greek exposures reveal the full picture of how institutional hedging drives SPTI price action.
SPTI Volatility Surface & Skew
The SPTI volatility surface maps implied volatility across strike price (moneyness) and time to expiration using SVI (Stochastic Volatility Inspired) calibration. Hot spots indicate where the market prices the most uncertainty. The 25-delta skew measures how much more expensive out-of-the-money puts are compared to equidistant calls - steep skew means heavy demand for downside protection. The IV edge map shows where individual options deviate from the SVI model's fair value, highlighting relative value opportunities for traders.
SPTI Options Flow & Sentiment
SPTI options flow tracks put/call ratio, total call and put volume, open interest, and net premium direction. A falling put/call ratio with rising call volume signals bullish sentiment. Elevated put volume and rising open interest on puts may indicate institutional hedging or bearish bets. Net premium flow shows whether money is flowing into calls or puts on balance.
SPTI 0DTE Gamma Exposure
Zero days-to-expiration (0DTE) gamma measures the gamma exposure from options expiring today. 0DTE options have become a dominant force in intraday market structure. When 0DTE gamma is large relative to total GEX, expect amplified intraday moves as dealers hedge rapidly decaying positions. The OI-weighted average DTE reveals whether overall positioning is concentrated in short-dated or long-dated options.
SPTI Volatility Skew by Expiry
The SPTI skew profile shows how implied volatility varies across delta (from 10-delta puts to 10-delta calls) for each expiration. Steep put skew means the market is paying a premium for downside protection - common before earnings or macro events. A flat or inverted skew may signal squeeze risk or speculative call buying. Comparing skew across expirations reveals where event risk is priced.
SPTI Theta Decay by DTE
SPTI theta decay shows the aggregate time-decay exposure by DTE bucket. Near-term options (0-7 DTE) experience the steepest theta burn - this is where premium sellers capture the most decay. For SPTI, the theta-by-DTE breakdown helps income traders identify which expiration windows offer the highest decay rates relative to gamma risk.
SPTI Bid-Ask Spread & Liquidity
SPTI options liquidity profile compares ATM bid-ask spreads to wing (OTM) spreads. Tighter spreads at ATM strikes mean better execution for traders. Wide wing spreads indicate thin liquidity on out-of-the-money options - important for spread traders and tail-risk hedgers. Active contract counts show market depth.
VIX Term Structure
The VIX term structure maps volatility expectations across time - VIX9D (9-day), VIX (30-day), VIX3M (3-month), and VIX6M (6-month). Contango (upward-sloping) is the normal state, where longer-dated vol exceeds near-term. Backwardation (inverted) signals acute market stress. The VIX futures basis shows the premium or discount of 3-month vol expectations versus spot VIX - positive basis means vol sellers collect roll yield.
SPTI Market Context
Broader market context for SPTI options: VIX level (overall market fear gauge), Fed Funds rate (monetary policy), and 10-year Treasury yield (risk-free rate benchmark). These macro factors affect options pricing across the board - rising rates increase the cost of carry, while VIX spikes correlate with wider spreads and higher IV across names.

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.

Key concepts behind the data on this page - learn how to read dealer positioning, volatility, and options flow.
What is Gamma Exposure (GEX)?
Gamma Exposure (GEX) measures the total gamma held by options market makers across all strikes and expirations for . When dealers are long gamma (positive GEX), they buy dips and sell rips - dampening volatility. When they are short gamma (negative GEX), they amplify moves in both directions. The gamma flip level marks where dealer positioning shifts from stabilising to destabilising.
What is Volatility Risk Premium (VRP)?
The Volatility Risk Premium is the difference between 's 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 - vol is underpriced.
What is Implied Volatility (IV)?
Implied Volatility is the market's forecast of how much will move, expressed as an annualised percentage. ATM IV (at-the-money) reflects consensus expectations. The IV term structure shows how expectations change across time - contango (rising) is normal, while backwardation (inverted) often signals a near-term event like earnings.
What is Options Skew?
Options skew measures how much more expensive out-of-the-money puts are compared to equidistant calls for . The 25-delta skew shown above compares 25Δ put IV to 25Δ call IV. Steep skew means the market is paying up for downside protection. Inverted skew (calls richer than puts) can signal squeeze positioning or strong bullish sentiment.
What are DEX, VEX, and CHEX?
DEX (Delta Exposure) measures directional risk - how many shares dealers must trade when the stock moves. 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 for .
What is a Volatility Surface?
The volatility surface maps implied volatility across two dimensions: strike price (moneyness) and time to expiration. The heatmap above shows 's IV at selected strikes and expirations. 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.
