Rank Symbols: GEX Level Map, Option Flow, Call/Put Walls & Volatility Rank
Scan ranked symbols by options flow, GEX, the Level Map, call/put walls, IV vs realized volatility, and open any symbol's research page. The live GEX screener and flow leaderboard.
The Symbols view of the Rank workbench is a ranked leaderboard of underlying names — stocks, ETFs, and indices. Where the Contracts view answers "which exact option contracts are hot?", Symbols answers a higher-level question: "which names are seeing the most interesting flow right now, and how is each one structurally positioned?"
The two views share a selected trading date and workbench scope, but read different sources: Contracts ranks traded contracts from the session flow; Symbols uses an independent full-chain symbol catalog with flow context. You can scan symbols, drill into a name, and continue into contracts without losing your selected session. Open Rank Symbols with valid trial or paid access.
Note: The old standalone Option Chain Analysis tool is retired. Its GEX, Vol, Positioning, and Chain views now live on each symbol's Symbol Research page, which a Rank row, its ticker chip, or the primary Symbols navigation opens.
The Symbols view at a glance
The Symbols leaderboard: session controls and Saved Views on top, the ranked table below, with filters, the Vol toggle, and export in the toolbar.
- Session & Saved Views — which trading session you're looking at (
__latest__or a historical date), plus the saved filter/column view driving the screen (this control is also where filters live — see below). - Contracts / Symbols tabs — switch between contract-level and symbol-level ranking. You're on Symbols.
- Vol toggle, Columns, Export — switch to a volatility-focused layout and sort, manage columns, and export what you see with valid access.
- Symbol leaderboard — the full-chain catalog of names, initially sorted by flow activity; symbols are not limited to contracts that traded.
Unlike the Contracts view, Symbols does not carry a row of "opportunity brief" summary cards above the table — its headline surface is the ranked table itself. The two Rank leaves share the selected trading date and watchlist or single-symbol scope, while each keeps its own data source and presentation. (For watchlists and filters in depth, see Watchlists and Filters.)
Use Symbols when you do not yet know what to study. It is the "start wide" screen: find the names where flow, volatility, and structure are most worth investigating, then narrow down into contracts and individual prints.
Reading the symbol leaderboard
The table is ordered "trader-first": flow signal leads from the left, structure and reference data trail to the right. The four small Inspect icons on each row open that symbol's research page directly on one view.
The symbol leaderboardRank names by net flow — an emerald DEX signal stacked beneath its blue gamma structure. The tallest tower leads.
The columns are grouped, roughly left to right:
Identity and Inspect
- Symbol and asset type (stock / ETF / index).
- Inspect — four small per-row icons that open the symbol's research page directly on its Flow, Positioning, GEX, or Vol view, without first landing on Overview.
Flow headline (the signal)
- Premium — total and net premium traded in the name's options. Big premium = big money at work.
- Net DEX — the net directional lean of the flow (bullish positive, bearish negative). See Delta Exposure (DEX).
- Net DEI — how large that directional flow is relative to the name's typical volume, shown as a size. It lets you compare a mega-cap and a small-cap fairly. (DEI is always read as a magnitude; direction comes from Net DEX and Sentiment.)
- Sentiment — a simple bullish / bearish label from the sign of the net flow. A balanced name shows no side.
- Call % — the share of premium spent on calls. High Call % leans bullish; low leans bearish.
You'll also find bullish DEI, bearish DEI, call/put premium, and trade counts here for a fuller read of how the day split.
Beginner reading order:
- Start with Premium and Net DEX to understand size and direction.
- Check Net DEI to ask whether that direction matters relative to normal volume.
- Use Sentiment and Call % to see whether the flow is one-sided or mixed.
- Only then read GEX, IV, sector, earnings, and market cap as context.
Structure (the backdrop)
- GEX Environment — a regime badge describing the name's gamma backdrop (more on this below). This is the only GEX column on the leaderboard; the fuller picture lives in the GEX view of the symbol's research page.
Volatility (where IV is rich or cheap)
- IV30 (30-day implied volatility), IV Rank, IV percentile, skew, term-structure slope, and butterfly.
- RV20 / RV30 — trailing realized (historical) volatility over the last 20 or 30 completed sessions, shown beside IV30 so you can compare what the market is pricing forward against what actually happened.
- IV30 − RV20 — the spread between the two, shown as descriptive context. It is not a mispricing signal or a trade trigger by itself — it is a starting point for asking why implied and realized volatility disagree.
Reference (context)
- Sector, market cap, average stock volume, and earnings — static context to frame the name.
The full-chain list uses recent intraday flow for its default ordering and prior-period structure for context (open interest and daily volume from the latest snapshot). A symbol can remain in the catalog without a recent print. Check each field's represented session before comparing them.
Default columns and the Vol layout
The toolbar has a Vol view toggle:
- Default layout shows the available flow, structure, volatility, and reference columns. Use Columns to hide fields you do not need.
- Vol layout temporarily focuses the visible columns on symbol, type, spot, sector, earnings, IV30, RV20, RV30, IV30 − RV20, IV Rank, IV Percentile, skew, term slope, and butterfly — sorted by IV30 − RV20 descending. Handy when screening volatility; Exit Vol restores the broader layout.
Column layout and sort order belong to the active Rank Saved View (see below). Valid presentation edits auto-save to its definition; the Vol toggle is a focused way to change that presentation.
Inspecting a symbol: Symbol Research
Click any row, its ticker chip, or an Inspect icon to open that name's Symbol Research page (/app/symbols/<symbol>). It opens over the table, so Back returns to the same sort, filters, page, and scroll without reloading.
Test app, Symbol Research for SPY, session of Oct 20, 2026 (captured Oct 21). The session line names the represented session and when its structure was built; Overview draws the Call Wall, Put Wall, and Gamma Flip on the price chart.
The header names the symbol and the session it represents, with the time its structure was built. Go to Latest leaves a pinned session, Refresh snapshot reloads on demand, and Ask AI opens TradingFlow AI on what you are looking at. Six views:
- Overview — snapshot price and candles with the Call Wall, Put Wall, and Gamma Flip overlays, plus the Rank session cards for the name.
- Positioning — full-chain max pain and open interest by strike, with today against the prior session. For more on OI, see Option Chain and OI.
- GEX — the Level Map and full-chain modeled gamma detail, described below.
- Vol — IV against realized volatility, term structure, skew, and the surface, described below.
- Chain — one expiration's traded contracts with session bid/ask quotes, plus the collapsed full-chain structure table.
- Flow — session flow for the name, live prints during market hours on the latest session, and mapped-wall session flow, described below. The wall evidence sits behind Load flow evidence and is fetched only when you choose to.
All six views require valid trial or paid access. Every page and view is shareable by link (for example /app/symbols/SPY?tab=gex; add tradingDate=YYYY-MM-DD to pin a session). Older drawer links (?selectedSymbol=SPY&drawerTab=gex) still open the same page and view. Recipients without access complete the sign-in and plan flow before seeing the data.
GEX: the Level Map
Open the Gamma Exposure (GEX) tab for the full structural picture behind the leaderboard's regime badge. Its summary surface is the GEX Level Map: the selected scope's chain-backed levels organized into one actionable read —
- the nearest structural level above spot,
- an exact at-spot node when one exists,
- the nearest level below,
- and the continuous gamma-regime transition (the Flip), reported separately since it's a repriced price level rather than a strike.
Levels that land on the same exact strike merge into a labeled node — Call Wall, Put Wall, Gamma Magnet, 0DTE Top, or Max Pain — each shown with its dollar distance, percent distance, and distance in Daily-ATR terms, plus its share of gross GEX in the selected scope. A Price & GEX Levels chart sits beside the map: real candles (interval selector from 1m up to daily), with optional VWAP and prior-day high/low (PDH/PDL) overlays, a log-scale toggle, a chart layers control (Core / Magnet / Max Pain / 0DTE) that chooses which of the map's levels draw on the chart, a PNG screenshot export, and an external TV link that opens the same symbol on TradingView for free-form analysis.
You can scope both the Level Map and the chart to All expirations, Today · 0DTE, Weekly (1–7 days), or Monthly (8–31 days) — the same scope control drives the Flow tab below.
For how positive and negative gamma may shape price movement, see Greeks & GEX. GEX Environment is a modeled structural reading tied to the displayed session and expiry scope. Read its structure date alongside flow dates; it is not a price forecast or an observation of dealer inventory.
Flow: session flow at the GEX walls
The paid Flow tab answers a specific question: did today's flow actually push toward the Call Wall, toward the Put Wall, or nowhere in particular? Press Load flow evidence once to unlock it.
Session flow at GEX walls. Each wall gets its own Net DEX and a transparent Flow-aligned / Flow-against / Mixed status.
- Selected-range GEX profile — a chart-first view of Call and Put GEX by strike, with the Put Wall, Structure Spot, and Call Wall called out and their exact levels.
- Wall audit cards — one for the Put Wall, one for the Call Wall, each stating whether that session's flow was Flow-aligned, Flow-against, or Mixed relative to the wall, along with the Net DEX behind that read, matched contracts, observed prints, and open-interest coverage. Every card explains why through a "Why this status?" link — this is descriptive evidence, never a hold/break forecast or a probability.
- 30-session flow history — the existing symbol-wide daily trend, collapsed by default; it appears once there's enough history to be useful and isn't filtered by the wall scope above.
Use the same All / 0DTE / Weekly / Monthly scope switch here as on the GEX tab — changing it updates the wall map, the audit cards, and the GEX tab together, so you're always reading the same window of the chain.
Vol: implied vs. realized, and the surface
The Vol tab separates two different questions: is volatility rich or cheap right now (this session), and what does the full volatility surface look like (a standing snapshot of the chain).
- IV Rank and IV Percentile are labeled as one-year context; the session's skew and term slope are labeled with their own date, so you never mistake a longer-horizon stat for a same-day one.
- The IV30 vs. RV20/RV30 comparison from the leaderboard reappears here with more room, alongside the spread.
- The implied-volatility surface is built from contracts actually observed trading in the session, and every cell is classified as Measured, Interpolated (a small, well-supported gap), or Unsupported (a gap too wide, or too far out, to estimate responsibly). Entitled users can inspect the heatmap and expand the 3D surface. This is descriptive structure, not a forecast or an event detector.
Saved Views and historical sessions
Two capabilities carry across both Rank tabs at once, saved from a single Rank saved views dialog (opened from the session/view control in the toolbar):
Saved Views cover filters, column layout, and sort order for both Contracts and Symbols in one payload — including the GEX Environment and GEX Context filters shown here.
- Saved Views — a paid, account-owned way to store your filters plus each tab's column layout and sorter together, with one view marked Default (loads automatically) and one marked In use (the active session). Rank Contracts covers the full mechanics — creating, renaming, and reverting a view — in depth; everything there applies here too, since one view always covers both tabs.
- Historical sessions — instead of only
__latest__, a paid user can pick any date retained by both Rank data sources. A historical session is settled: it stays fixed and does not auto-refresh, and it stays selected as you move between Contracts and Symbols. If a requested date stops being available, Rank keeps showing the date you asked for along with Retry and Go to Latest — it never silently substitutes a different day.
Access and trial
Home and these guides are public. Rank Symbols, its leaderboard, Symbol Research pages, Chain quotes, filtering, historical sessions, saved views, and export require valid trial or paid access. Guests are prompted to sign in; signed-in accounts without access see the plan gate before Rank data renders. Eligible new accounts can explore the full workbench during the seven-day trial without a card.
Handoff to Option Trades
When a name stands out and you want the trade-by-trade tape, use Open Option Trades in the symbol's Flow view: Option Trades has the full tape, filters, alerts, and export. To follow one exact contract instead, open it from Rank Contracts; its Open in Option Trades carries the contract and session into Historical. Access recovery returns visitors to their selected in-app destination after verification.
What to do next
You now know how to scan names, read each one's flow and gamma backdrop, and inspect any symbol before acting. Next, learn to shape the leaderboard to exactly what you care about in Watchlists and Filters — see the same GEX picture packaged as a guided narrative report in Cookbooks & Market Recap — or jump straight to the tape with Option Trades.
