Free COIN GEX - Coinbase Gamma Exposure
Free COIN GEX maps Coinbase gamma exposure by strike for an options market closely linked to cryptocurrency volatility. Select expirations, then generate the chart to compare net GEX, call wall, put wall and gamma flip without treating any single level as a price forecast.

What is Gamma Exposure (GEX)?
Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
- Gamma Flip: Where total GEX changes from negative to positive
Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).
Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).

Understanding COIN gamma exposure
COIN's wide strike spacing and high implied volatility mean its call wall and put wall sit further from spot (in percentage terms) than a typical stock's - but they are still respected levels, particularly the put wall during crypto drawdowns. Traders often read COIN GEX alongside Bitcoin's own derivatives data for a fuller picture of crypto-complex positioning.

COIN GEX methodology and limitations
QuantWheel calculates COIN GEX from the selected expirations, available options data and the formula displayed in the calculator. The result summarizes modeled gamma exposure by strike.
GEX is a model output, not observed dealer inventory or a price forecast. Open interest does not identify who owns an option, and the displayed call wall, put wall and gamma flip can change when the inputs or selected expirations change.
COIN GEX FAQ
What is COIN GEX?
COIN GEX estimates gamma exposure across listed COIN options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. COIN GEX does not reveal actual dealer positions or predict where COIN will trade.
How do I read the COIN call wall and put wall?
QuantWheel labels the COIN call wall as the strike with the largest positive modeled GEX and the COIN put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the COIN price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the COIN gamma flip?
The COIN gamma flip is the price where modeled net gamma crosses zero for the selected COIN options data. Compare it with the current price and the shape of the strike chart. The COIN gamma flip is a model output, not a trading signal.
Which expirations should I use for COIN GEX?
Start with the nearest COIN expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which COIN contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the COIN GEX calculator free?
Yes. You can run up to three free COIN GEX calculations per day on the public tool. After using those calculations, continue for free in the GEX Sandbox. Check the current QuantWheel pricing page for plan access details.
