GM Options Chain — Open Interest, Implied Volatility, Max Pain & Gamma Exposure
Analyze the complete GM options chain including strike-level open interest, real-time implied volatility (IV), max pain levels, gamma exposure, dealer positioning, and options flow trends. This dashboard provides data-driven insights for traders building directional or hedging strategies around GM.
Dealer–Gamma Regime
A combined view of GM’s total gamma exposure (GEX) and Dealer Position Index (DPI). This helps identify whether dealer hedging flows support mean reversion or trend continuation in the current options market.
In a long gamma regime, dealers hedge against price moves, strengthening mean reversion and suppressing volatility.
A Strong Net Long Options profile indicates how dealers hedge daily flows, influencing whether trends extend or revert.
Price moves are likely to stay range-bound.
The short-term gamma flip is near 48.10 , with intermediate positioning around 48.10 . The mid-term gamma flip remains near 50.00.
With Long Gamma and a neutral DPI trend , the current setup favors Mean Reversion Zone .
Dealer hedging flows interact with gamma positioning to form short-term volatility regimes. Stronger directional movement is more likely when gamma is short or unstable.
The options structure reflects a moderate bearish bias. Downside factors are present but not dominant. Medium confidence reflects partial agreement across option-based signals.
Put-Side Positioning Insight
On the put side, the bearish positioning looks
mainly like hedging.
This reflects caution and short-term protection rather than a true bearish call.
Confidence: 67%
Important intraday and swing-trading price levels derived from max pain, open interest distribution, and gamma positioning. These price levels are derived from Max Pain analysis, gamma exposure trends, and open interest dynamics, which are crucial factors for assessing market sentiment and potential price movements. Traders can use the support and resistance levels to identify key price zones for entry or exit points, while the pivot point serves as an important reference for gauging trend direction.
Bullish flow suggests upside interest toward 83.72 (1.17% above spot).
Bearish positioning points to downside pressure toward 79.76 (3.62% below spot).
Options flow strength: 0.62 (0–1 scale).
ATM Strike: 83.00, Call: 0.53, Put: 0.65, Straddle Cost: 1.18.
Estimated using ATM implied volatility, OTM option flow, and dealer hedging conditions to capture the market-implied price range.

1. Core Volatility Signal (0.82% Standardized 1-Day Move)
“The ATM straddle implies a standardized 1-day move of
0.82%.”
This means:
- Implied volatility is below normal.
- The market expects relatively muted price action.
- Little near-term uncertainty is being priced.
📌 Plain interpretation: Subdued volatility — traders expect limited movement.
2. Expected Price Range (Next 3 Days)
The options market is pricing the following risk range:
80.94 – 83.45
Upper: +0.85%
•
Lower: -2.19%
🔻 Bearish Skew — downside risk exceeds upside potential.

DPI Trend Index
Dealer Position Index (DPI) tracks how options dealers are positioned.
Rising DPI → dealers long options (mean reversion).
Falling DPI → dealers short options (trend amplification).
DPI does not predict direction. It only answers one question:
once price moves, will the market reinforce that move?
DPI reflects the direction and strength of dealer gamma exposure — not a bullish or bearish call.
Latest Trend Interpretation:
Gamma Exposure & Expiry Risk Zones
Gamma Exposure (GEX) defines how option dealer hedging interacts with price moves. Large expiries can sharply alter hedging pressure and trigger volatility shifts.
Market GEX vs Price History
Aggregate gamma exposure plotted with underlying price. Sharp GEX declines or flip-zone tests often precede increased volatility.
