You get a ranked table, symbol lookup, per-symbol inspection drawer (with Overview and Day trend), and optional AI summary tools—tuned to how flow is actually distributed that day, not a generic “volume only” read.

Symbol inspection drawer (Overview / Day trend for the selected name):

What you see

The app is built around an as-of session date for the flow cohort. Rank and columns reflect that date’s symbol-day aggregates. Typical columns include rank, symbol, type (e.g. ETF, index, stock), sentiment, total premium, call %, net put premium, DEX, and DEI—so you can scan leaders by size, direction, and delta impact.

• Symbol lookup — Type a ticker in the toolbar to open the symbol inspection drawer (same public navigation surface as clicking a row).
• Table — A ranked, column-rich view; exact sort and filter behavior depends on tier (see below).
• Symbol drawer — Overview for the selected symbol and date, plus a Day trend view: above the history table, charts show stacked call/put premium by session and DEX lines (bullish-sum, bearish-sum, and signed net DEX). History table premium columns line up with the list semantics; sentiment labeling stays consistent with the ranked list.
• Open Option Trades — From the drawer header, jump to Option Trades in a new tab with the same symbol in the URL. Available to all tiers; the table does not duplicate a separate per-row “flow” link—drawer → Option Trades is the main handoff.
• AI summary (optional) — When enabled, generate or refresh a synthesis (takeaways, conclusion with stance and confidence, risks) from the current view. May require entitlement.
• Download CSV — Export for subscribers where available.

Ranks for filtered views are meant to reflect filtering against the full per-date symbol-day cohort first, then ordering—so “top under these conditions” stays meaningful, not a shallow slice filtered after the fact.

Public preview, public drawer, premium controls

Symbol-level analysis is designed with a clear boundary:

• Default list preview — Guests and free users see the canonical preview ranking for the app’s preview contract, without needing a subscription to browse the surface.
• Symbol drawer — Opening a symbol, switching Overview vs Day trend, refreshing drawer data, and deep-linking into drawer state are part of the public navigation experience.
• Premium-side controls — Changing list sort, submitting symbol or filter changes that move off the preview request, advanced filters (e.g. filter popover with numeric range bounds on premium/DEX/DEI columns), date and other server-backed list mutations where gated, and CSV export are paid (or otherwise entitled) interactions, enforced in the app and on the server—not merely client-side nags.

In short: you can see the ranked story and open any symbol’s evidence path without paying; you unlock full workflow—custom sorts, full filter sets, and export—on subscription.

Filters and table (premium when gated)

Quick filters

Where your tier allows, you can typically adjust:

Toolbar with session date, quick filters, and the ranked grid:

• Date — Session date (defaults to the latest available in the system).
• Type — ETF, index, or stock.
• Sentiment — All, bullish, or bearish flow tone (aligned with net-DEX list rules at high level).
• Min premium — Thresholds such as
  All → $250K → $1M → $5M → $10M → $25M → $50M → $100M (values as shipped in the product).

Numeric range filters

From the Filters popover, set min/max on columns such as total call premium, total put premium, net put premium, total premium, net DEX, and net DEI. Active filter chips should appear under the toolbar when applied.

Column sorting from headers may be gated for unpaid users (sort attempts can be blocked before local state changes), while paid users can reorder to hunt leaders by premium, call %, net put, DEX, or DEI.

Where to find it

In TradingFlow, use Option flow analysis → Symbol-level, or go directly to /app/market-rank.

Related workflows

• Option Trades — Trade-level flow for a symbol; use the drawer’s Open Option Trades handoff to land with the symbol already set in the app.
• Option Chain Analysis — Gamma, cross-sectional vol, and per-symbol chain depth in one surface at /app/option-chain-analysis for structure and OI context on names you find here.

The standalone cross-symbol OI change rank app has been retired; for historical OI on a single symbol inside the app, use Option Chain Analysis’s drawer (e.g. OI Time Machine) instead of looking for a separate OI-rank listing.

Contract drawer (inspect one contract—intraday flow vs historical context):

What Contract-level analysis shows

Contract-level analysis mixes intraday delayed flow with prior-session open interest (OI) and daily volume context. By keeping the horizon hybrid, it prevents misreading the surface as purely live or entirely T+1.

• Option flow analysis (Contract-level) — See top contracts ranked by metrics like premium, vol/OI ratio, trade count, and net DEX.
• Server-driven ranking — The server owns ranking, filtering, pagination, and window anchoring, guaranteeing that you're looking at the true top contracts matching your criteria, not just sorted leftovers.
• Contract drawer — Click a row to open the drawer: Intraday focuses on short-interval flow buckets with trade-price overlay in tooltips; Historical (day-over-day) charts OI with ΔOI markers, bullish/bearish DEX bars, ask/bid printed size, and session-level context in the table—premium is surfaced in the table, not as a duplicate series on that chart.
• Access boundary — Default list preview and opening the contract drawer (including public inspection payloads) are part of the browse surface for lower tiers; changing rank mode, applying narrowing filters, column-header sorts, and similar list-control mutations are premium-gated. Pagination (page / pageSize) is a read cursor within the default unpaid query—not treated as a premium gate by itself.

Finding What Matters

You can use powerful narrowing filters to zero in on exactly what you want:

• Filter by symbol, put/call, expiry scope, or exact expiration date.
• Use post-aggregation floors like minPremium and minVolOi to find contracts with meaningful activity size.
• The rank list uses the default sorting metrics (premium, volOiRatio, tradeCount, netDex) so the most important action naturally floats to the top.

How the ranked grid looks while you tune symbol, expiry scope, and post-aggregation floors:

Exact-Contract Handoff

Contract-level analysis is discovery-first. But ranking without evidence isn't actionable. The default table layout makes contract identity scannable instantly. Once you spot a contract of interest, you can smoothly transition into the Option Trades view.

The handoff preserves all your exact-contract filters (symbol, expiration date, strike, put/call). This means you land precisely on the evidence view without manually rebuilding your search state.

See it in action

In the app, use Option flow analysis → Contract-level and go to /app/contract-rank (first-class route with its own metadata). Use narrowing filters for discovery, open the drawer for intraday vs historical context, and use Open Option Trades when you want trade-level evidence—the handoff preserves exact-contract filter fields.

Market KPI cards

Six summary cards sit above the table and update with every data fetch — they give you the market-level picture before you touch any filters.

Each card shows both the percentage and the dollar amount so you always have absolute size for context.

Same surface with the six KPI cards directly above the tape:

What Option Trades shows

The app uses real-time (or near real-time) trade data. Choose between aggregated and raw mode to either scan for block-sized flow or drill into exact Time & Sales.

• Aggregated mode — Trades for the same option symbol in the same second are rolled into one row. Ideal for spotting block trades and unusual flow; columns include size, premium, sentiment, DEX, DEI.
• Raw mode — Unaggregated Time & Sales for exact trade-level detail when you need it.
• Symbol filters and watchlist — Focus on specific underlyings or use your watchlist to track a set of names.
• Sortable columns — Reorder by premium, size, sentiment, DEX, DEI, or time. Changing sort (outside Live Mode) is a premium-gated interaction on the live app.

Filters and filter modal

Click Filters in the toolbar to open a comprehensive filter panel. Every filter type is organized into sections:

Date and time

• Date range — Pick any day, month, quarter, or year range from a flexible date selector (operators: is, before, after, between). Only trading dates with available data are selectable.
• Time range — Narrow to a specific time window within the trading day.

Asset type, side, and trade attributes

• Asset type — Stock, ETF, or Index.
• Type (Call/Put) — Show only calls, only puts, or both.
• Side — Above Ask / Ask / Mid / Bid / Below Bid — filter by where the trade printed relative to the spread.
• Moneyness — ITM, ATM, or OTM.
• Sentiment — Bullish, Bearish, Neutral.
• Trade type — Block (single trade) or Sweep (two or more simultaneous exchange prints).

Numeric ranges

All 13 dimensions support both min and max bounds:

Boolean toggles

• Recent Earnings only — Show only trades occurring near a recent earnings event.
• Opening Position only — Filter to trades that appear to be opening new positions (size > OI proxy).
• Watchlist only — Restrict the table to your saved watchlist symbols.

Applied filter summary

Active filters are shown as inline chips below the toolbar so you always know what's applied without reopening the panel.

Persistent preferences

For paid subscribers, Option Trades behaves like a professional desktop workstation: one Option Trades Preference document holds your saved view (filter state plus column layout). That view hydrates before the first server fetch where applicable, with a local backup path if preferences are slow to arrive.

Guests and signed-in unpaid users do not load that premium saved view by default. They start from the canonical public preview unless the URL carries allowed overrides—so you are not silently running someone else’s saved screener on a free account.

When you have unsaved changes, a Save button appears in the toolbar. Leaving the page with unsaved changes can trigger a browser confirmation (paid flows).

Live Flow mode

Activate Live Flow to stream incoming option trades in real time via WebSocket. The table updates continuously as new trades arrive.

Rules governing Live Flow to keep the feed coherent:

• Sort by Time (Descending) required — Before enabling, the table must be sorted by time descending. New trades appear at the top without random jumps. If sorted differently, the app offers a one-click fix to apply the correct sort and start streaming.
• Controls lock while live — Filters, pagination, and sort controls are disabled during streaming to prevent UI drift.
• Market hours — Live Flow is only active during US market hours. Attempting to start outside market hours shows an informational guard.
• Exit to adjust — Pause the stream any time to update filters or sorting, then re-enable.

Live Flow is a subscription feature.

The flow grid is the surface Live Flow appends into—while streaming, sort stays locked to time descending:

Shareable filter links

You can share a URL that encodes your current symbol and filter state. When a recipient opens the link, the app tries to initialize with those filters—tier rules still apply: unpaid users may fall back to preview when the link encodes non-preview control state, per the access contract in the product.

Browser notifications

Enable the notifications toggle in the Settings menu (⚙️ icon in the toolbar) to receive browser push notifications when trades matching your current filters arrive during Live Flow. Requires browser notification permission.

Where to find it

In TradingFlow, open Option Trades in the main nav or go directly to /app/option-trades. Use aggregated mode for flow scanning and blocks; switch to raw when you need tick-level detail. Combine with Symbol-level analysis on /app/market-rank for flow-ranked symbols, Option Chain Analysis on /app/option-chain-analysis for gamma and cross-sectional vol, and Contract-level analysis on /app/contract-rank when you need ranked contracts with an exact-contract handoff back into Option Trades.
