GEX Levels v3 [Barrett]GEX Levels v3 draws options gamma exposure (GEX) levels for SPY and QQQ as labeled horizontal lines, across three time horizons from a single input.
WHAT IT SHOWS
- Flip: the price where dealer gamma changes sign. Above it, moves tend to be dampened; below it, moves tend to be amplified.
- CW / PW: call wall (heaviest call strike, overhead ceiling) and put wall (heaviest put strike, floor).
- P1 / P2: positive-gamma resistance strikes above price. PS1 / PS2: support strikes below price.
- N1 / N2: negative-gamma strikes where moves tend to accelerate.
- AG1 / AG2: high absolute-gamma strikes that price tends to stick to.
- MP: max pain. EM+ / EM-: the expected-move band.
- HVL: highest-volume strike. FC: full-chain gamma flip.
HOW IT WORKS
The levels are calculated outside TradingView from the full options chain and entered as one comma-separated string. The indicator parses that string and draws each level with its label. A 0 in any slot means that level is not present and is skipped.
String format: 0DTE (16 values) | WEEKLY (10 values) | MONTHLY (10 values)
0DTE order: P1,P2,PS1,PS2,N1,N2,AG1,AG2,Flip,MP,EM+,EM-,CW,PW,HVL,FC
WEEKLY / MONTHLY order: P1,P2,N1,N2,AG1,AG2,Flip,MP,EM+,EM-
HOW TO USE
1. Add the indicator to a SPY or QQQ chart.
2. Open settings (gear) and paste the level string into "All Levels (String)".
3. Use "Active View" to show 0DTE, WEEKLY, MONTHLY, or ALL.
4. Use the SPY string on SPY and the QQQ string on QQQ. The levels change daily.
WHY IT IS DIFFERENT
One input loads three expiry horizons at once. A level that appears on 0DTE, weekly, and monthly together is being defended across expirations, and those stacked levels are usually the most significant of the day.
These levels are for reference only and are not trade signals.
