## Quick answer

The gamma flip is an estimated underlying price where a model’s aggregate dealer gamma exposure changes sign. Traders use it to frame potential changes in hedging behavior—not as a guaranteed support, resistance or market forecast.

## Key points

- **A modeled threshold:** The level comes from option-position estimates and assumptions, not a directly reported exchange value.
- **Hedging context:** Positive and negative gamma regimes may interact with price movement differently.
- **Always moving:** Spot, volatility, time, open interest and new trading can shift the estimated flip.

## From gamma to a flip level

Gamma estimates how quickly an option’s delta changes when the underlying moves. Dealers who hold option inventory often adjust stock or futures hedges as delta changes. A gamma-exposure model aggregates contracts across strikes and expirations and applies assumptions about which side of those positions dealers hold.

At some underlying prices, the aggregate estimate can cross from positive to negative or the reverse. That modeled crossing is called the gamma flip. Different data inputs and assumptions can produce different levels, so there is no single official gamma flip published by the exchange.

## Positive versus negative gamma regimes

In a simplified positive-gamma regime, dealer hedging is often described as selling as price rises and buying as price falls, which can dampen movement. In a simplified negative-gamma regime, hedging may require buying into strength and selling into weakness, potentially reinforcing movement.

Real markets are more complicated. Dealer books contain many instruments, position direction is estimated, hedges can be anticipatory and other participants can overwhelm modeled flows. The regime is context for scenarios, not a law of price behavior.

- Compare spot price with the flip and the largest strike concentrations.
- Watch whether price holds above or below the level rather than reacting to one touch.
- Recheck the estimate after large price, volatility or time changes.
- Account for expiration days and event-driven option demand.
- Use price structure and risk limits independently of the model.

## Why gamma-flip estimates differ

Models may use open interest, intraday volume or both; apply different assumptions to calls and puts; include different expirations; and estimate volatility or dealer direction differently. A level calculated before the open may not match one updated during a fast session.

CaymanBot presents the gamma flip beside the full exposure profile because the distribution matters more than an isolated number. Key strikes, total exposure, spot and the age of the snapshot help users judge how much weight to place on the estimate.

## Frequently asked questions

### Is the gamma flip support or resistance?

It can become a reference level, but it is not guaranteed support or resistance. It represents a modeled change in aggregate gamma exposure.

### Can the gamma flip move during the day?

Yes. Price, implied volatility, time decay and new options activity can change contract sensitivities and the aggregate estimate.

### Why do platforms show different gamma flip levels?

They may use different data windows, dealer-position assumptions, volatility inputs, expirations and calculation methods.

### Does negative gamma mean the market will fall?

No. Negative gamma describes modeled hedging sensitivity, not direction. It may be associated with movement being reinforced in either direction.
