The one idea behind everything

You don't need to know options math. You need one mental model: big options dealers (market makers) are forced to buy and sell futures to stay neutral, and where they're forced to trade is predictable. Those forced-trading prices are your levels.

Greek #1 — Gamma
Price-driven
Dealer hedging triggered by price moving. Builds walls, floors, and trapdoors. The backbone of every day.
Greek #2 — Vanna
Volatility-driven
Hedging triggered by the VIX moving. Sets the day's drift and tone. Context — never its own level.
Greek #3 — Charm
Time-driven
Hedging triggered purely by the clock. Pulls price to a pin into the close. Strongest Wed & Fri afternoons.
↯
That's the entire framework. Gamma builds the structure, vanna tilts the drift, charm pins the close. Everything else on this site is detail hanging off those three hooks.

Gamma from zero
What gamma actually is, why dealers hedge, and the difference between a pinning day and a trending day. Open Gamma →
2
Vanna & volatility
How the VIX quietly steers the market, the four vanna regimes, and why we use it as context, never a line. Open Vanna →
3
Charm & the clock
Why afternoons pin, how time decay drags price to a strike, and the charm clock that runs every expiry day. Open Charm →

The levels at a glance

These are the nine things your chart can show you — in the indicator's real colors. Full deep-dive on each lives in the Levels page.

Ceiling
Strongest wall above — likely cap. Fade rallies into it.
Floor
Strongest wall below — likely support. Buy dips into it.
Magnet
Secondary pin. Price gravitates toward it on calm days.
Trapdoor
Break it and the move accelerates. The trend-day fuel.
Vol zone
Fast, whippy air-pocket. Cross it, don't camp in it.
Charm pin / fade
Time-decay pull (pin) or push (fade). Afternoon force.
Gamma flip
The regime line. Bullish above, bearish below.
Confluence ★
Two greeks agree. Your highest-conviction zone.

Glossary

The exact vocabulary used across the academy and in your indicator. One source of truth.

Gamma (GEX)
How fast a dealer's hedge changes as price moves. Positive = stabilizing, negative = destabilizing.
Vanna (VEX)
How a dealer's hedge changes as implied volatility (the VIX) moves. Context only in our system.
Charm
How a dealer's hedge changes as time passes — even with price and IV frozen.
Ceiling
The strongest positive-gamma wall above price. One per board.
Floor
The strongest positive-gamma wall below price. One per board.
Magnet
Any secondary positive-gamma pin that isn't the main ceiling or floor.
Trapdoor
The strongest negative-gamma strike near price. Break = acceleration.
Vol zone
Interior negative-gamma territory. Fast, whippy, no reliable reactions.
Charm pin / fade
Positive charm pulls price to the strike (pin); negative charm pushes it away (fade).
Gamma flip
The price where net dealer gamma changes sign — the regime boundary.
Confluence
A strike where gamma and charm both qualify. Highest conviction.
Regime
The board's overall character: positive-gamma (pinning/range) or negative-gamma (trending).
Size
A level's raw strength bucket: solid → big → massive → extreme.
Strength bar
0–100 ranking of a level within its own greek. Not compared across greeks.
Expected range
The floor-to-ceiling band. Where price tends to live on calm days.
Pin / pin gravity
The tendency of price to be drawn to and held at a dominant strike into expiry.
0DTE
Zero-days-to-expiry options — expiring today. Where gamma and charm bite hardest.
ES offset
The points added to an SPX strike to get the matching ES futures price.
