What Is the GEX Rating?
The GEX Rating is a 1-to-5 directional gamma score that summarizes the current net dealer gamma exposure for a given underlying. A rating of 1 or 2 means dealers are net long gamma -- a bullish or stabilizing context where their hedging activity dampens market moves. A rating of 4 or 5 means dealers are net short gamma -- a bearish or amplifying context where their hedging accelerates moves in whatever direction the market is already going. A rating of 3 is transitional: gamma is roughly balanced and the market can break either way with lighter mechanical influence.
The GEX Rating distills the entire DealerEdge heatmap into one actionable number so you can orient yourself in five seconds before every trade. It does not tell you which direction the market will move -- it tells you how the market will behave mechanically once it starts moving. That distinction is what makes it useful. You can explore the underlying gamma mechanics in What Is Gamma Exposure, or see the full rating in context on the DealerEdge feature page.
Why Regime Matters More Than Direction
Most traders spend the majority of their time asking "which direction will price go?" The GEX Rating addresses a prior and equally important question: "how will the market behave once it starts moving?" A momentum strategy applied in a Rating 1 environment -- where dealer hedging is constantly fading moves and pulling price back to the Anchor -- will produce repeated small losses as your trades get faded before they develop. The same strategy in a Rating 5 environment, where dealer hedging amplifies every directional move, can produce strong results on the same signals.
Matching your strategy to the current GEX regime is one of the highest-leverage adjustments you can make, because it affects every trade you take that day, not just individual entries.
The Five Ratings in Detail
Rating 1 -- Strong Positive Gamma
Dealers carry significant net long gamma across the strike ladder. Their hedging is countercyclical: they buy aggressively when price dips and sell aggressively when price rises, compressing intraday range and pulling price back toward the Anchor Point. This is "pinning mode." Intraday ranges are tight. Breakout attempts get faded repeatedly. Mean-reversion strategies shine here.
Best strategies: iron condors and butterflies centered at the Anchor, premium selling (credit spreads), range scalping by fading moves away from the Anchor, buying the bounce at support Defense Lines.
Rating 2 -- Moderate Positive Gamma
The market is still in a positive-gamma regime but with less compression. Price can travel more freely between Defense Lines and may test them from inside before bouncing back toward the Anchor. There is room for directional movement within the gamma corridor, but sustained breakouts are still uncommon. This is the most tradeable rating for mean-reversion setups -- strong enough mechanics to provide an edge, enough room to let trades breathe.
Best strategies: credit spreads with moderate-width wings, mean-reversion entries at Defense Lines with stops just outside, debit spreads targeting the Anchor from a Defense Line.
Rating 3 -- Neutral or Transitional
Gamma exposure is balanced or light. The market is not being mechanically constrained in either direction. This often occurs when the market is between major expirations, when large positions have been unwound, or when options activity is broadly distributed across strikes rather than concentrated. In Rating 3, the gamma structure gives you less information -- direction depends more on flow, news, and technicals than on dealer mechanics.
Best strategies: reduce position size, wait for a clear directional catalyst before entering, favor defined-risk trades (vertical spreads rather than naked positions), and check the GEX Flip Point to see how close the market is to a regime shift in either direction.
Rating 4 -- Moderate Negative Gamma
Dealers are net short gamma. Their hedging is now procyclical: when price falls, they sell to hedge; when price rises, they buy. Instead of dampening moves, they amplify them. Defense Lines weaken -- a level that would have held firmly in a Rating 2 environment may only slow price briefly before it continues through. Momentum strategies gain an edge because dealer flows are now working in the same direction as price moves.
Best strategies: momentum entries in the direction of the prevailing trend, trailing stops to stay in trending moves, breakout trades through Defense Lines (expecting follow-through rather than reversal), avoiding premium-selling strategies that depend on range-bound behavior.
Rating 5 -- Strong Negative Gamma
The strongest amplification regime. Intraday moves can be large and fast. Defense Lines frequently fail to hold as dealer hedging adds fuel to directional moves rather than resisting them. This is the environment where orderly pullbacks can turn into sharp selloffs and modest breakouts can run 2-3x further than expected. Volatility is typically elevated. Premium selling is dangerous here -- undefined-risk short positions can move against you faster than you can manage them.
Best strategies: directional momentum trades with defined risk (debit spreads or long options), clear stop levels, avoiding mean-reversion trades and premium selling entirely. Size down if you are directional, because moves can overshoot in either direction.
How to Use the Rating in Practice
Open DealerEdge at the start of every session. The GEX Rating appears prominently at the top of the module, color-coded from green (1) through yellow (3) to red (5). This takes five seconds. Before you read a chart, before you check flow, before you look at news -- check the GEX Rating. It frames every subsequent decision.
Write the rating down (or say it aloud) as part of your pre-session routine. Many experienced users also check it after major intraday events -- a sharp sell-off, a Fed speaker, a major earnings print -- because the rating can shift during the session if large options positions are opened or closed rapidly.
Concrete Example
For example, suppose you are watching SPY at 9:30 AM. DealerEdge shows a GEX Rating of 2 with the Anchor at $520 and the GEX Flip Point at $514. SPY opens at $518. The rating tells you: mean-reversion will work better than momentum today. You set your bias to fade strong opens rather than chase them, look for dips to Defense Lines as entry points, and target the $520 Anchor as your intraday profit level. You avoid buying breakouts above $520 because the positive-gamma environment will likely fade those extensions back to the Anchor.
Now suppose a macro headline drops at 10:15 AM and SPY gaps down to $512 -- below the Flip Point at $514. DealerEdge's rating rapidly shifts toward 4. The environment has changed mid-session: dealer hedging is now amplifying the move downward. Your mean-reversion playbook is no longer appropriate. You reassess, check whether the shift is sustained, and switch to a momentum-compatible framework if the rating holds at 4 through the next 15-minute candle. This is an illustrative scenario, not a guaranteed outcome.
Common Misconceptions
- The GEX Rating does not predict direction. A Rating of 1 does not mean the market will go up. It means the market will be range-bound and mean-reverting regardless of which direction it moves. A Rating of 5 does not mean the market will crash. It means whatever direction the market chooses, dealer hedging will amplify it. Direction comes from flow, news, and technicals; regime comes from the GEX Rating.
- The rating is not static. It updates continuously as options positions change. A session that starts at Rating 2 can shift to Rating 4 after a large options trade or a significant price move. Check the rating periodically throughout the session, not just at the open. Major catalysts -- Fed decisions, earnings, economic data releases -- can cause rapid rating shifts.
- Rating 3 is not neutral in a bad way. Traders sometimes dismiss Rating 3 as uninformative. In reality, a Rating 3 environment is a warning to reduce exposure and wait for clearer conditions, which is a genuinely useful piece of information. Many avoidable losses come from sizing up in transitional environments where the gamma structure gives no mechanical edge to either direction.
