The full guide
0DTE — Same-Day Options
Who this is for: Traders playing expiration-day (0–1 DTE) options on indexes and fast movers, working off dealer positioning and Apex levels. Fast, mechanical, and levels-driven — the highest-skill path on the platform. The levels give you an edge; they don't replace price-action discipline.
⚠️ 0DTE options decay by the hour. A bad entry can't be "held back to even." Size small, define your exit before you enter, and treat the levels as the plan: when the level breaks, the trade is over.
The workflow
- Check the market weather first. Before any ticker, pull SPY/QQQ on the Futures GEX page. Is price above or below the gamma flip line? Above = dealers buy dips, calmer tape, favor calls. Below = negative gamma, dealers amplify moves, drops come fast, favor puts. Then check the aggregate Apex view for a dominant magnet (score 100) — it pulls the whole index toward it.
- Let the morning settle. The cleanest 0DTE reads come after the morning's big money has chosen a direction — not at the 9:30 bell. Apex levels refresh about every 15 minutes; let them stabilize before you commit.
- Trade the level, not the move. On the ticker's Apex chart in single-expiry (today's) view, find the heavy wall just below price (your call floor) or just above it (your put ceiling). Enter at the wall; target the next dominant magnet. Don't chase price through open space.
- Re-verify constantly. If your support wall disappears or jumps away, the institutions have moved their money — the plan is broken, so cut it. On a violent macro move, re-pull the levels before doing anything.
Futures (NQ / MNQ)
- Use the Futures GEX calculator for ES/NQ levels. You can also draw QQQ Apex levels onto an NQ chart with a QQQ→NDX→NQ converter — QQQ's Apex data tracks the index closely.
- Converter levels are accurate during New York market hours and drift when the market is closed (options don't trade pre-market, so GEX reflects prior-session structure until the 9:30 open).
- MNQ is one-tenth the size of NQ (same price, one-tenth the tick value) — the lower-risk way to learn the level reads with real money on the line. Mind round-trip fees on small moves.
Before you enter — the checklist
- Index above or below the gamma flip identified (calls vs. puts bias)
- A clear Apex wall to enter against, with a magnet as the target
- Taken after the morning's money settled, not on the open
- Liquid contract with a tight bid-ask — 0DTE spreads punish you
- Hard stop set; position sized so a same-day total loss is survivable
Common mistakes
- Chasing the move instead of entering at a level.
- Holding a decaying 0DTE "until it comes back."
- Trading index 0DTE through a macro headline without re-verifying levels.
- Entering right before a weekend or a level-invalidating event.
