Six levels that drive the session.
DealerEdge surfaces the strikes market makers are most likely to defend. Learn them once, read them every day.
- 01Anchor Point
A tight cluster of gamma where price tends to pin for stretches of the session.
TacticalRange-trade around it until gamma rolls off. - 02Flip Point
The strike where dealer net gamma crosses zero - character of the tape changes here.
TacticalRegime change. Expect more volatility once price crosses. - 03HVL · High Volume Level
The strike with the most dealer exposure on the board. Price gravitates here.
TacticalScalp toward HVL, fade away from it. - 04Call Wall
Heavy call gamma above price. Acts as resistance as dealers hedge by selling rallies.
TacticalFade rallies into the call wall. - 05Put Wall
Heavy put gamma below price. Acts as support as dealers hedge by buying dips.
TacticalFade selloffs into the put wall. - 06Defense Lines
Two to three secondary support zones where market makers will hedge aggressively, often near a major expiration.
TacticalExpect rapid mean reversion if price approaches.
Two regimes. Two playbooks.
Dealer gamma determines whether price dampens or expands. Know the regime before you size the trade.
Long gamma
Positive GEXWhen dealers are long gamma, they sell into rallies and buy into dips to hedge. Result: a price-dampening, range-bound, mean-reverting session.
Playbook
- Fade extremes, scalp toward the anchor
- Sell premium - vol stays contained
- Smaller size, tighter stops
Short gamma
Negative GEXWhen dealers are short gamma, they sell into dips and buy into rallies to hedge. Result: a move-amplifying, trending, high-volatility session.
Playbook
- Trade with momentum, hold winners
- Buy premium on breakouts - vol expands
- Wider stops; expect range-extension
126 tickers, streaming live.

Quick answers.
What is GEX, in plain English?
GEX (gamma exposure) measures the net options gamma held by market makers at each strike, expressed in dollars. When dealers are long gamma, they hedge by selling into rallies and buying into dips - this dampens price moves. When they're short gamma, their hedging amplifies moves and the tape gets more volatile. DealerEdge visualizes GEX as an interactive strike × expiry heatmap so you can see where dealers are pinned before you trade.
How often does the heatmap update?
Live during regular trading hours. Cells stream over SSE and the price marker tracks the tape in real time, so you see dealer flow move into and out of strikes as it happens. Outside RTH you have a pre-market snapshot at 08:00 ET and a close snapshot at 16:05 ET, plus Replay for any prior session.
Which tickers are covered?
126 tickers total: 5 indices (SPX, NDX, DJX, RUT, VIX), 11 popular ETFs (SPY, QQQ, IWM, DIA, SMH, XLF, SOXL, TQQQ, SQQQ, TNA, SRTY), and 110+ liquid single-name stocks including AAPL, MSFT, NVDA, AMZN, META, GOOGL, TSLA, NFLX, AMD, INTC, COIN, PLTR, HOOD, and CRWD. 0DTE is supported across all of them.
What's the difference between Heatmap, Pro, and Focus mode?
Heatmap shows the full strike × expiry matrix for one ticker - best for scanning a single name in depth. Pro shows up to seven tickers side by side, each with the nearest expiration - best for comparison across SPY/SPX/QQQ or your own set. Focus shows a 1-minute OHLC chart with Anchor, Flip, Call/Put Walls, and Defense Zones overlaid, plus a right rail with Watchlist quotes, Regime Timeline, and Flow Pulse - best for execution.
Does DealerEdge work on 0DTE?
Yes. 0DTE is a first-class expiration across all modes - labeled 0DTE / 1DTE / NDTE on the heatmap. The Focus chart respects 0DTE Anchor and Flip points the same as any other expiry.
When does AI Analysis refresh?
Post-market only. AI Analysis is a daily summary per ticker - market outlook, suggested trade strategy, and risk notes - generated against the day's GEX once the close snapshot lands. It's not a live, intraday read; we're explicit about that so you don't size off stale text.
Can I replay past sessions?
Yes. Replay mode is available inside all three modes - Heatmap, Pro, and Focus. Pick a date, scrub the timeline, and play back at 1×, 3×, 5×, or 15×. Granularity is one minute. Useful for post-market review of how levels held or broke. Recent sessions are kept on hand for replay; we'll publish the exact retention window once we finalize it.
Do I need a Pro subscription for DealerEdge?
Yes - DealerEdge is subscription-only. There is no free tier. It's included with every Trade Echo plan at $199/mo alongside OptionFlow, Darkpool, AlgoEdge, Cortex AI, and Copy Trading.
How does $199/mo include this when standalone GEX tools cost $699/mo?
Standalone GEX tools price up because they sell one product. Trade Echo sells a bundle - six products on one subscription, one feed, one terminal - and prices the bundle at $199/mo. You get DealerEdge plus five more products for less than a third of single-feature alternatives.
What are the dealer regime playbooks for?
They're a default playbook for the two states the tape can be in. Long gamma sessions tend to mean-revert - fade extremes, sell premium, smaller size. Short gamma sessions tend to trend - trade with momentum, buy premium on breakouts, wider stops. The playbooks aren't trade signals; they're context for how you size and which entries you take.
Are vanna and charm available?
Honest answer: not yet. Today the heatmap exposes GEX, Vol, VEX, Notional, and %Gamma. Vanna and charm aren't visualized - we'd rather ship what's actually wired up to live data than mock them on the page.
Does it work pre-market and after hours?
The live refresh runs during regular trading hours. Outside RTH, you have the pre-market snapshot at 08:00 ET and the close snapshot at 16:05 ET, plus Replay for any prior session. Focus mode quotes update with broker data; the heatmap waits for the next snapshot.
