Expectations, limitations & FAQ
TL;DR
- Data updates only 9:30–4:00 ET, Mon–Fri; outside those hours everything is frozen at the last close.
- GEX levels are reaction points, not entry signals — never take an entry from a level alone.
- Levels are price-based, not timeframe-based: pair GEXmon with whatever chart you already trade.
Hard limitations, stated plainly
- Market hours only. GEX is computed from live options-chain data, which updates only 9:30 AM–4:00 PM ET, Mon–Fri. Outside those hours everything is frozen at the last session’s close, and the badge reads Closed.
- Levels shift intraday, and 0DTE resets daily. Thresholds are per-ticker starting points, calibrated over time.
- What GEXmon will never do: predict direction, give entries, or replace risk management. Full stop.
The realistic value statement: better session context, fewer trades against the regime, pre-marked mechanical levels, and permission to stand aside.
FAQ
You can’t be sure — nobody can. GEX levels are reaction points, not entry signals: they mark where a reaction is likely, never that it will happen or which way to trade it. Align them with your own bias, structure, and orderflow for execution. This is the guide’s core message, restated as a direct answer.
Trust them as context with a real mechanical basis, never as standalone predictions. We deliberately don’t market a “hit rate,” because levels aren’t binary signals — a wall that slows price, gets defended, then breaks all “worked” as information. Believe the level plus your confirmation, never the level alone.
The levels are derived from US options-chain data, which only updates 9:30–4:00 ET. Overnight, the last session’s levels are frozen — they can still act as reference zones (standing dealer positioning doesn’t vanish), but there’s no live hedging-flow data behind them, so reactions are less reliable. Treat overnight use as reference-only, at reduced confidence; fresh reads resume at the US open.
GEX levels are price-based, not timeframe-based — a wall at 21,412 is at 21,412 on every chart. The dashboard is timeframe-agnostic; pair it with whatever execution timeframe you already trade (5-minute is a sensible intraday default).
Options data takes a few minutes to populate at the open, and the open itself is dominated by mechanical dealer rebalancing. Wait for it — a blank or jumpy zero gamma in the first couple of minutes is expected, not a bug.
Volume = today’s live positioning (fast, 0DTE-dominated; it drives the regime engine). OI = standing positioning (slower, more durable). Agreement between them — or a confluent tag — is the strong signal.
“Wait” is common because neutral/transitioning conditions are common, and the engine won’t manufacture an edge (Part 7). Walls break when fresh demand overwhelms dealer inventory — and the break is information, then the level flips roles (Part 4). For which lens fits your style, see Part 6.
“Just tell me how to read it step by step”
That’s exactly what the 60-second read in Part 9 is. It’s the canonical, repeatable routine — start there and come back to any concept part as needed. New to all of it? Read Parts 0–2 in order first.
Do this on the dashboard now
- Bookmark the 60-second read — it’s your standing answer to “how do I use this?”
- Outside 9:30–4:00 ET, treat every level as frozen reference-only.
- Before any trade, say out loud: “this level is a reaction point, not a signal.”
- Skim the glossary if any term still feels fuzzy.
