01 · Basics
What is GEX?
GEX stands for Gamma Exposure — the aggregated gamma risk across all market participants. It shows how strongly market makers are forced to hedge when price moves.
When dealers sell options, they take gamma risk onto their books. Since their delta changes with price, they must continuously buy or sell futures to stay delta-neutral. The larger the GEX at a strike, the stronger this hedging obligation.
Key Insight
GEX is not an indicator waiting for price. It is a leading force that actively influences price. You see what dealers must do — not what they want to do.

02 · Primary Levels
Call Wall & Put Wall
The two most important zones define the natural daily range for NQ. They emerge from the gamma concentration at the strongest strikes in the options market.
Call Resistance (Call Wall)
The strike with the highest call gamma. Dealers must sell progressively more NQ futures as price rises → mechanical ceiling. Fade setup when price approaches and momentum fades.
Put Support (Put Wall)
The strike with the highest put gamma. Dealers buy NQ futures to hedge → natural support. Long setup on approach. Note: A close below = potential downside acceleration.
When Call Resistance and Put Support sit on the same strike, an especially strong magnet forms — NQ is powerfully drawn to it and can consolidate there for hours (pin effect).
03 · Gamma Flip
High Vol Level — The Switch
The HVL (High Vol Level) is the boundary between positive and negative gamma regime. It is the single most important level in the entire system — it determines how you trade throughout the entire day.

First Question Every Morning
Check Tradinghub: Is NQ above or below the HVL? That is your regime filter for the day. All other levels are interpreted within this context. Skipping this step means fighting the market.
04 · Secondary Levels
GEX 0 to GEX 10
The GEX levels (GEX 0, GEX 1, GEX 2 ...) are additional strikes ranked by gamma concentration. GEX 0 carries the highest gamma within the 1D expected move, GEX 1 the second highest, and so on.
They activate between primary levels in the chart and show where NQ encounters intraday reactions. Most notable: when a GEX level coincides with a primary level → high-concentration zone.
Real Example NQ · April 17, 2024
GEX 0 at 17,950 (aligned with Put Support 0DTE) · GEX 1 at 17,800 (= Put Support) · GEX 2 at 19,000 (= Call Resistance) · GEX 4 at 18,000 as intraday resistance after rejection.
05 · Hidden Zones
Blind Spots
Blind Spots are reaction zones not visible from primary strike concentration. They emerge from correlated gamma exposure in related assets and secondary open-interest clusters.
They explain why NQ sometimes suddenly stalls after breaking a primary level — at points that show no obvious significance on the chart. Dealers encounter unexpected gamma and are forced to hedge.
Why This Matters
After an HVL or Put Support break, many traders expect continuation. Blind Spots explain why that continuation often stalls exactly where no classical support is visible. Those who know them avoid chasing. Those who don't call it "random market noise".
06 · Market Regime
Positive vs. Negative
The gamma regime defines the fundamental character of the day. The same technical analysis produces different outcomes in positive versus negative gamma — because the market responds structurally differently.
Positive Gamma — Dealer Long Gamma
Dealers buy on the way down, sell on the way up. The market is stabilized. Ranges develop. Mean reversion works. Realized volatility is low.
Negatives Gamma — Dealer Short Gamma
Dealers sell on the way down, buy on the way up. Moves are amplified. Breakouts accelerate. Stops get triggered. Realized volatility is elevated.

07 · Trading Setups
Strategies for NQ
Here are the four most common, directly actionable setups based on gamma levels. All require that you know the current regime (HVL).
Short · Fade
Fade at Call Resistance
NQ approaches the Call Wall with fading momentum. Dealers must sell.
1. Price approaches Call Resistance
2. Momentum fades (volume decreasing)
3. Short entry near the level
4. Target: HVL or next GEX level below
Long · Bounce
Bounce at Put Support
NQ falls into Put Support. Dealers buy futures. Natural support.
1. Price approaches Put Support
2. Volume fades, momentum flattens
3. Long entry with stop just below
4. Caution: A close below Put Support negates the setup
Short · Acceleration
Break Below Put Support
NQ breaks decisively below Put Support — regime flips negative. Dealers sell with the trend.
1. Close below Put Support (relevant timeframe)
2. No VWAP reclaim
3. Short on retest from below (now resistance)
4. Targets: GEX level below, 1D low
Range · Pin
Range Trading in Positive Gamma
NQ above HVL, Call Wall above, Put Support below. The market is held within the range.
1. Regime: Positive Gamma (price above HVL)
2. Sell near Call Resistance
3. Buy near Put Support
4. Tight stops · small, consistent gains
Break · Momentum
Breakout from Negative Gamma
In the negative gamma regime (below HVL), moves are amplified. A breakout from negative GEX pockets forces dealers into pro-cyclical hedging.
1. Identify negative gamma zone in the Net GEX Chart
2. Wait for breakout from the zone with high volume
3. Entry in the direction of the break — dealers hedge with you
4. Next positive gamma zone = probable target
