The gamma levels the big services charge $299/month for. Computed fresh every morning. Delivered as paste-ready thinkorswim studies.

thinkScript can't read an options chain, so no GEX tool exists natively on TOS. We compute the levels from full option chains every morning and deliver them before the open.

13 SYMBOLS, EVERY TRADING MORNING (by 9:00 AM ET):

• Indices: SPX, SPY, NDX, QQQ

• The entire Mag7: NVDA, TSLA, AAPL, MSFT, GOOGL, AMZN, META

• Sectors: XLK, SMH

Each study plots:

• Call Wall (green) — where dealer call gamma concentrates overhead

• Put Wall (red) — where put gamma concentrates below

• Zero Gamma (yellow) — the flip between vol-suppressing and vol-amplifying dealer regimes

• Magnet Strike (white) — the massive mixed-OI pin, flagged so you don't mistake it for support

• Front-expiry walls — the nearest-expiration battlefield (0DTE on indices, weeklies on stocks)

Plus: /ES and /NQ mapped levels — SPX and NDX levels translated to the futures on your chart, basis-adjusted daily — and a short morning levels note: the numbers, the regime, what changed overnight.

BUNDLED FREE: the complete SMC Suite for thinkorswim ($49 sold separately) — FVG zones, order blocks, BOS/CHoCH structure, liquidity sweeps, killzones — yours while subscribed.

Positioning levels, not signals — they show where dealer hedging concentrates, not where price will go. Computed from delayed public options data. Educational use only, not financial advice. Cancel anytime.
