Gammatrix™
FREEGamma & Exposure · WebSocket Streaming · Free Tier
Overview
Gammatrix is the flagship analytics window on the Ohey platform. It renders a real-time gamma exposure chart for any US equity with listed options, showing aggregate dealer gamma by strike price. The chart reveals where market makers are long or short gamma — the structural force that determines whether price is stabilized or amplified at each level.
Gammatrix connects via WebSocket to Ohey's real-time analytics pipeline, which calculates gamma exposure across all listed strikes and expirations for the selected ticker.

How to Read the Chart
| Element | Meaning |
|---|---|
| Green bars | Positive gamma — dealers are long gamma at these strikes. They buy dips and sell rallies → price is stabilized. |
| Red bars | Negative gamma — dealers are short gamma. They sell into selloffs and buy into rallies → price moves are amplified. |
| Gamma Flip line | The strike where gamma transitions from positive to negative. Crossing this level typically triggers a regime change in price behavior. |
| Gamma Wall | The strike with the highest absolute gamma concentration. Acts as a magnet or barrier for price due to heavy dealer hedging. |
| Spot Price marker | Current underlying price overlaid on the chart for reference. |
Use Cases
- Identify support/resistance: Strikes with heavy positive gamma act as magnets — price tends to gravitate toward gamma walls. Use this to set limit orders near high-gamma strikes.
- Anticipate volatility shifts: When the underlying approaches or crosses the gamma flip level, expect increased volatility. This is a signal to adjust position sizes or deploy vol strategies.
- Time entries with dealer flow: In positive gamma environments, dealers tend to stabilize price — mean-reversion strategies are commonly considered. In negative gamma, price tends to trend — momentum strategies are commonly considered.
- Pre-OPEX analysis: Use the expiration breakdown to see how gamma exposure will change as near-dated options roll off. Heavy pinning at gamma walls increases on expiration days.
