Gamma walls: call walls (resistance) & put walls (support)
TL;DR
- Walls are ranked by dollar gamma, so the biggest number is the level that actually matters — no eyeballing.
- Green = call/positive concentration, red = put/negative. Colors describe positioning, never trade direction.
- Levels are two-sided: a put wall is support above it and resistance once broken. The break itself is information.
Walls are the strikes where dealer hedging piles up — mechanical resistance above spot, mechanical support below. They’re your key levels for the session. Our options guide breaks down why call walls and put walls form — the dealer-hedging mechanics behind every level here.
How GEXmon shows it
The Walls panel splits into Call walls · resistance (above) and Put walls · support (below). Each wall shows its strike, a strength bar, its size in dollars (e.g. +$10.1B), a secondary figure, and its distance from spot (“29 pts above”). A Volume / OI toggle switches the model, and a confluent / split pill sits on each side.
Green = call / positive-gamma concentration. Red = put / negative-gamma concentration. Colors describe positioning, never trade direction. A big red bar at $490M means “expect a reaction zone here,” not “go long” or “go short.” The level is a place price is likely to react; which way it resolves is your read, not the bar’s.
The value we add
- Ranked in dollars — the top wall is objectively the one that matters; no eyeballing a histogram.
- Distance in points from spot, so you instantly know how far the level is.
- Volume vs. OI in one click — today’s live positioning vs. standing positioning.
- Confluence detection — a confluent tag when the Volume and OI models agree on a side’s strongest wall.
Yes. Levels are two-sided reaction zones. A put wall is support while price is above it; once broken, it flips to resistance (and a call wall does the reverse). Walls break when fresh options demand overwhelms dealer inventory — and the break itself is information. A level respected three times can break on the fourth.
Validate a level in four steps
- Is it a top-ranked wall in dollars? If it’s not near the top of the list, it’s not a key level.
- Does it appear in both Volume and OI views, or carry the CONFLUENT tag? Agreement is strength.
- Which side of it is price on, and what’s the regime? A wall means different things above vs. below, in positive vs. negative gamma.
- Is flow building at or defending it? (Part 5.) Then wait for a price reaction plus your own orderflow confirmation. The level alone is never the trade.
Correct use & expectations
Mark the top one or two walls each side as your session’s key levels. In positive gamma, expect deceleration into big call walls; in negative gamma, expect speedbelow put walls. Use walls to frame targets and invalidation for trades you find with your own method — they’re magnets and friction zones, not guaranteed reversals.
Do this on the dashboard now
- Read the top wall on each side and mark those two strikes on your chart.
- Click the Volume / OI toggle. Levels that appear in both — or carry confluent — are your strongest.
- Run the four-step check on the level nearest price before you trust it.
- Frame targets and invalidation around walls; take the actual entry from your own orderflow.
