Options Lab

Gamma exposure visualization, volatility surface, and volume/OI analysis

Open in App

Overview

Options Lab is an analytics workbench for understanding options market structure. It provides three specialized visualizations: Gamma Exposure (GEX) by strike, Volatility Term Structure, and Volume/Open Interest analysis. These tools help you understand where dealer hedging creates price magnets, how volatility is priced across expirations, and where the largest open positions sit.

Tabs

GEX Visualizer

Gamma Exposure (GEX) chart showing the aggregate gamma exposure of market makers at each strike price. GEX reveals where dealer hedging activity creates support and resistance zones.

  • -Bar chart of net gamma by strike price
  • -Positive gamma zones (dealers buy dips, sell rips — acts as support/resistance)
  • -Negative gamma zones (dealers amplify moves — high volatility areas)
  • -Current price marker on the GEX profile
  • -Ticker search to analyze any optionable stock
Volatility Lab

Volatility term structure showing implied volatility across different expiration dates. Reveals whether the market is pricing near-term or long-term uncertainty.

  • -Term structure curve (IV by expiration)
  • -Contango vs backwardation identification
  • -Historical IV comparison
  • -Ticker-specific analysis
Volume & OI

Options volume and open interest breakdown by strike price. Shows where the most contracts are concentrated and where new positions are being opened.

  • -Volume and open interest by strike (call and put)
  • -Put/call ratio by strike
  • -Max Pain calculation (strike with maximum expiring OI)
  • -Ticker-specific analysis

Understanding GEX (Gamma Exposure)

Gamma Exposure measures how much market makers need to buy or sell the underlying stock to maintain delta-neutral hedges. This hedging activity creates observable price effects:

GEX ZoneDealer BehaviorPrice Effect
Positive Gamma (above zero)Dealers buy when price drops, sell when price risesDampens volatility — price tends to mean-revert and stay range-bound
Negative Gamma (below zero)Dealers sell when price drops, buy when price risesAmplifies volatility — moves accelerate in both directions
GEX Flip PointThe strike where GEX transitions from positive to negativeKey inflection level — above it markets are calm, below it they get volatile
High GEX strikesLarge gamma concentration at a specific strikeActs as a magnet — price tends to gravitate toward high GEX strikes near expiration

Tip

The GEX flip point is one of the most useful levels to know. When the index or stock is trading above it, expect mean-reverting, low-volatility behavior. Below it, expect trend-following, high-volatility moves.

Volatility Term Structure

ShapeMeaningImplication
Contango (upward sloping)Near-term IV < long-term IVNormal market — no imminent fear, gradual uncertainty increase over time
Backwardation (downward sloping)Near-term IV > long-term IVMarket is pricing a near-term event (earnings, FOMC, etc.) — elevated short-term fear
FlatIV similar across expirationsUncertainty is evenly distributed — no strong event pricing
KinkedSpike at a specific expirationBinary event priced at that date (e.g., FDA decision, earnings)

How to Use

  • Enter a ticker symbol in the search bar on any tab
  • Start with GEX Visualizer to understand where dealers are positioned
  • Identify the GEX flip point and high-gamma strikes as key levels
  • Switch to Volatility Lab to see if the market is pricing near-term events
  • Check Volume & OI to see where the largest positions are concentrated
  • Use Max Pain as a reference for where price might gravitate by expiration
  • Cross-reference GEX levels with support/resistance from the Chart page
  • Check for backwardation ahead of known events (earnings, FOMC meetings)

Note

GEX data is most useful for index-level analysis (SPX, SPY, QQQ) where market maker hedging activity is most concentrated. For individual stocks, GEX is most meaningful for highly liquid, large-cap names with active options markets.
