Gamma Exposure (GEX) Levels - JMerc567
Here's how to use it effectively:
Setting Up (Daily Pre-Market Routine)
Get your GEX data from one of these free/paid sources:
SpotGamma — best for SPX/SPY
Market Chameleon — free options data
SqueezeMetrics — DIX/GEX for SPY
Then open the indicator Settings and fill in:
Field What to enter
Gamma Flip Strike The price where dealers flip from positive to negative gamma
Call Gamma Wall Strike with the most call open interest / highest positive gamma
Put Gamma Wall Strike with the most put open interest / highest negative gamma
Levels L1–L8 Other high-OI strikes you want to watch
Reading the Dashboard
Regime (most important):
POSITIVE GEX (price above flip) → dealers are short gamma → they buy dips and sell rips → expect mean reversion, low volatility, price pinning near strikes
NEGATIVE GEX (price below flip) → dealers are long gamma → they buy drops and sell bounces acting as amplifiers → expect trending, higher volatility, larger moves
Environment label:
PINNING (low vol) — price tends to gravitate toward high-OI strikes, great for range strategies
TRENDING (high vol) — price can move fast and far, momentum strategies work better
Dist to Flip % — how far price is from the regime change level. Under 0.5% = watch closely.
Key Levels
Call Gamma Wall (green line) = strong resistance — dealers hedge by selling as price approaches
Put Gamma Wall (red line) = strong support — dealers hedge by buying as price drops here
GEX Flip (yellow dashed) = the most important level — crossing it signals a regime change
Alerts
Set these up via TradingView's Alert dialog (clock icon):
GEX Regime Change — flip cross, potential trend shift
Price Near Flip ±0.25% — watch for acceleration or reversal
Price Near Call/Put Wall — key S/R test incoming
High-Volume GEX Event — diamond marker on chart, potential unpin
Tips
Update levels daily pre-market — GEX resets on each expiration (especially 0DTE Fridays)
The GEX Proxy oscillator (in the dashboard) is volume-based — not real GEX, but useful as a directional bias confirmation
On opex weeks (monthly expiration), GEX effects are strongest
