What is a Gamma Squeeze?
A gamma squeeze happens when dealers are forced to buy or sell the underlying asset to hedge their options positions, creating a feedback loop that amplifies price moves. In Bitcoin, this happens on Deribit where 85% of options are traded.
When dealers are short gamma, every price move forces them to hedge in the same direction — pushing price further. This creates cascading moves that can move BTC 5-10% in hours.
How Dealers Hedge
Market makers on Deribit are typically short the options customers buy. To stay delta-neutral, they must buy or sell BTC as the price moves:
- BTC rises: Dealers buy more BTC to hedge short calls
- BTC falls: Dealers sell BTC to hedge short puts
This hedging flow is mechanical and predictable. It creates two distinct market regimes.
Positive GEX Regime (Mean-Reversion)
When dealers are net long gamma, their hedging dampens price moves. They buy dips and sell rips. BTC tends to:
- Trade in a range
- Pin to high open-interest strikes
- Have lower realized volatility
Trading strategy: Sell strangles, fade extremes, scalp mean-reversion.
Negative GEX Regime (Trending)
When dealers are net short gamma, their hedging amplifies price moves. They sell dips and buy rips. BTC tends to:
- Trend strongly in one direction
- Have high realized volatility
- Make discontinuous jumps
Trading strategy: Trend-follow, widen stops, buy straddles.
Gamma Flip Level
The gamma flip is the BTC price where net dealer GEX crosses zero. Above the flip = positive gamma (mean-reverting). Below the flip = negative gamma (trending).
Mark the gamma flip on your chart. It acts as a regime boundary. When BTC crosses the flip, the character of the market changes.
Trading the Gamma Squeeze
Before the Squeeze
- Identify gamma flip level
- Mark major gamma walls (strikes with highest OI)
- Check if GEX is positive or negative
During the Squeeze
- If negative GEX: do not fight the trend
- If positive GEX: fade the extremes
- Watch for gamma flip crossover
After the Squeeze
- Expect mean-reversion if GEX flips positive
- Volatility often collapses after squeeze
Real Example: BTC $100K Gamma Wall
In December 2024, BTC approached $100,000 with massive call open interest at that strike. Dealers were short these calls. As BTC rose toward $100K, dealers had to buy more BTC to hedge. This buying pressure pushed BTC above $100K. Once above, dealers unwound hedges, creating volatility.

GEX Levels and the Spot Feedback Loop
Gamma exposure (GEX) measures how much the collective dealer book must buy or sell to stay flat spot exposure as BTC moves. When dealers are long gamma overall, price mean reverts: a tick upward makes dealers sell, pulling price back; a tick down makes dealers buy, cushioning the drop. When the dealer book is short gamma, the feedback flips: a rally forces gamma-the poor dealers to buy higher, and a dip forces them to sell lower, so streaks extend. That flip level is the gamma flip price, and squeezing through it is the mechanic that produces the violent vertical BTC candles.
Reading Deribit's Dealer Positioning
Deribit is the reference venue for BTC options, and its open interest is public data. With spot near 100k, the gamma walls at round strikes like 95k, 100k, 105k act as magnets: dealers hedge between strikes, filling the noise inside the range while suppressing deviation from it. Compute the dealer gamma at each strike as the product of option gamma, open interest, and per-unit size, then sum across expiries for the profile. The strike with the largest net dealer short gamma is the one the market is structurally moated to race toward when a squeeze begins.
Gamma Flip: Turning a Trend Into Chop
The most tradeable moments are the transitions. A rally that pushes spot from under the flip level to above it converts a trending regime into an asymmetric one: the sellers prop the falls, the mean-reversion regime returns, and the volatility decays into the next positioning cycle. Watch the flip level, not whatever the coin did yesterday. A break of gamma resistance is not automatically a rise even further; it is a change of which market participants earn on every price tick, which is the real information hiding in the microstructure.
A Squeeze Playbook With Strike Ladders
In a short-gamma regime on Deribit, the directional trade is rallies following the wall: buy ATM calls or a call spread near the wall when spot has flipped the level on rising open interest, and target the next strike wall's touch. In a long-gamma regime, the mean-reversion trade is fading the touch of the wall. Keep the ladder small and full-of-strategy: the first target is the next round strike, the second is the week's range extreme, and any stop sits beyond the source wall because those levels hold structurally in the near term. Chasing a squeeze you did not pre-plan is how most participants buy the top of the candle that ends it.
Why BTC Squeezes Are Bigger Than Equity Ones
Bitcoin squeezes amplify the same mechanics for three structural reasons: the market trades 24/7 so the reinforcement never sleeps, a large share of positioning lives in concentrated round strikes that sharp cash closes skew, and volatility itself is higher, which means larger delta per option. Small spot pushes near a wall get multiplied by dealer hedging demand at the exact moment that retail leverage tops up the same side. That is why a 3 percent day inside a wall feels ordinary and a 15 percent gap through a wall becomes the one smooth graph you cannot unsee.
- Compute dealer gamma per strike from public Deribit open interest.
- Find the flip level the spot must cross.
- Trade rallies in short-gamma regimes; fade walls in long-gamma regimes.
- Target the next wall, stop beyond the source wall.
- Size as if the second candle never shows up.
Vanna and Charm: The Gamma Family
Gamma is the headline and the family follows: vanna measures how gamma changes as implied volatility moves, and charm measures how delta decays with time - both matter in a squeeze, because a volatility spike and a few days of decay can flip a dealer's hedging direction mid-move. A gamma-flip thesis is stronger when vanna and charm point the same way, because the dealer book's rebalancing is not a single event but a rolling stream after the flip. Read them directly from the option surface using open-interest-weighted greeks per strike, and watch the family, not just gamma, on the transition day. The squeeze that changes colour is almost always the squeeze with the family turning first.
