## Quick answer

CaymanBot’s GEX heatmaps summarize options positioning by strike so traders can study where dealer hedging may reinforce or resist price movement. Compare gamma exposure, flip levels and key concentrations without reducing a complex market to a single number.

## Key points

- **Key strikes:** See where gamma exposure is concentrated across the selected options chain.
- **Regime context:** Use the gamma profile and flip level as context for stability, volatility and hedging behavior.
- **Multiple Greeks:** Premium access includes GEX, VEX and Charm heatmaps in one visual workflow.

## What is GEX?

Gamma exposure, commonly shortened to GEX, is an estimate of how option dealers’ delta exposure may change as the underlying price moves. Because dealers often hedge their inventories, changes in delta can create buying or selling pressure in the underlying. A GEX model aggregates contract-level estimates to show where that hedging sensitivity may be concentrated.

GEX is model-dependent. It relies on assumptions about dealer positioning and uses snapshots that change with price, time, volatility and open interest. It should be treated as a market-structure lens rather than a guaranteed forecast.

## How to read a gamma exposure heatmap

A heatmap makes the distribution across strikes easier to compare. Large concentrations can become reference levels because dealer hedging activity may increase as spot approaches them. The gamma flip is an estimated price where the net profile changes sign, potentially marking a shift in how hedging flows interact with market movement.

- Start with spot price and the largest positive and negative strike concentrations.
- Compare the current price with the estimated gamma flip level.
- Watch how the profile changes across expirations and after large price moves.
- Combine GEX with price structure, volume, volatility and event risk.
- Avoid treating a modeled level as fixed support or resistance.

## Use GEX with options flow

Options flow shows transactions; a GEX heatmap estimates the positioning landscape those transactions enter. Used together, they can answer different questions: where is activity appearing, and where might the existing options structure matter most? CaymanBot places heatmaps alongside flow, option chains, technical charts, alerts and backtesting to keep those questions connected.

Premium members can access GEX, VEX and Charm heatmaps. Coverage and freshness depend on available market data, and all values are for informational analysis only.

## Frequently asked questions

### What does positive GEX mean?

Positive net gamma is commonly associated with dealer hedging that may dampen price movement, but the interpretation depends on model assumptions and actual dealer positioning.

### What is a gamma flip level?

It is an estimated underlying price where modeled net gamma exposure changes sign. Traders use it as market-structure context, not guaranteed support or resistance.

### Which symbols can I view in the GEX heatmap?

CaymanBot supports major indexes and individual optionable symbols when sufficient data is available.

### Is GEX predictive?

GEX is an estimate of positioning and potential hedging sensitivity. It can help frame scenarios but does not predict the direction or size of the next market move.
