Alerts posted to Discord carry a block called Gamma Structure. It's a short read on what the options market itself was doing around that underlying at the moment the alert fired — where price is likely to get stuck, and where it's likely to run.

It looks like this:

NEUTRAL · spot 775.24 · 47s ago Net GEX 352,641 — positive (suppressive) Flip 814.31 (spot 39.07 below) ▲ Call wall 780.00 (+4.76) · Shelf 780.00 ▼ Put wall 765.00 · Shelf —

Five short lines. Here's what each one is telling you.

The idea in one paragraph

When you buy an option, somebody sold it to you — usually a market maker who doesn't want a directional bet. To stay neutral they buy and sell the underlying stock as it moves. Where all the open options sit decides which way they have to trade, and that buying and selling is big enough to push the stock around. Gamma Structure is a summary of where those pressure points are.

You don't have to believe any of this to trade the alert. It's background, the same way knowing there's earnings tomorrow is background.

Line 1 — bias, price, freshness

BULLISH, BEARISH or NEUTRAL, then the underlying's price at that instant, then how old the reading was when the alert posted.

Freshness matters. A reading taken 47 seconds before the alert describes the market the alert was called into. If it says several minutes, treat the levels as approximate. You may occasionally see structure flat appended, which means there wasn't enough shape in the data to say anything strong — read the rest loosely.

Line 2 — Net GEX

One number, with the important part spelled out in words after the dash:

• positive (suppressive) — dealer hedging pushes against moves. Rallies get sold into, dips get bought. Price tends to grind and mean-revert, and big trends are harder to get. Fast, wide moves are less likely.
• negative (amplifying) — dealer hedging pushes with moves. A move down begets more selling, a move up more buying. Price tends to trend and to move faster, and both directions get sharper.

The size of the number is a rough measure of how strongly. You don't need to interpret the raw figure — the word in brackets is the takeaway.

Tip

This is the single most useful line for a day trader. A long shot needing a big fast move is fighting the tape in a strongly suppressive regime, and has the wind behind it in an amplifying one.

Line 3 — Flip

The price level where suppressive flips to amplifying. It's phrased relative to where the stock actually is, so you don't have to work out a sign: "Flip 814.31 (spot 39.07 below)" means the stock is nearly 40 points under the level where the character of the market changes.

Far away — as in that example — and the regime is stable; you can expect the behaviour on line 2 to hold. Close by, and the market can change personality on a modest move, which is worth knowing before you size a trade.

Lines 4 and 5 — walls and shelves

These are the levels. The ▲ line is above, the ▼ line is below, and each pairs two different things.

• A shelf is a level that tends to hold. This is what most people mean by support and resistance.
• A wall is a level where a lot of open interest is concentrated. The call wall above usually acts as a ceiling — but the put wall below is not support.

Warning

The put wall is the most misread number in the block. It marks where dealer hedging works with the move rather than against it — so if price gets there, moves tend to accelerate, not stop. It's the trapdoor, not the floor. The support level on that line is the shelf.

That's exactly why each line prints its wall and its shelf together: they answer opposite questions and sit close enough that reading one as the other will cost you.

Where a distance is shown in brackets, it's from the current price — so "Call wall 780.00 (+4.76)" means resistance is $4.76 overhead.

When you see a dash

A — means that level did not qualify — nothing at that price carried enough of the open interest to be worth naming. It does not mean the data is missing or broken. In the example above there simply isn't a meaningful support shelf below.

Where it appears, and where it doesn't

The block is attached to alerts as they post. You won't see it on:

• Futures alerts — futures have no options chain, so there's nothing to measure.
• Thinly covered symbols — if we don't have gamma data for that underlying, the block is left off entirely rather than printed as a row of dashes.

What it doesn't do

Gamma Structure is context, not a signal. It does not change what the alert says, it does not change what your bot does, and no setting anywhere reads it. Nothing on your account behaves differently because of it.

Example

An alert comes in on a QQQ call with spot at 775.24. The block reads positive (suppressive) with a call wall at 780.00, less than $5 overhead. That doesn't make the alert bad — but it does tell you the move has a ceiling nearby in a regime that dampens moves. If you're the sort of trader who takes profit early rather than letting a runner run, that's a reason to lean on your take-profit rather than your trailing stop on this one.
