🔭 Scanner

The Scanner turns the heatmap workflow inside out: instead of looking up one symbol at a time, you point a set of filters at the entire US options universe — thousands of stocks and ETFs — and surface only the tickers whose GEX structure matches what you’re hunting for. Set your criteria and the matching names drop into a sortable grid you can drill into in one click.

Scanner \u2014 filter the US options universe by GEX-node proximity, put/call OI, King GEX, price and earnings

The Filter Panel#

The filter panel is where you describe the kind of setup you want. Each control narrows the universe; leave one untouched and it simply passes everything through. Combine a few and the grid collapses to a short, focused list.

  • T1% / T2% / Avg% — distance from spot to the strongest GEX node (Top1), the second-strongest (Top2), or the average of the top nodes. Tighten these to find tickers sitting right on a node — a classic pinning setup.
  • P/C OI — put/call open-interest ratio. Screen for put-heavy or call-heavy names by setting a minimum or maximum.
  • |K| (King GEX) — magnitude of gamma concentrated at the King strike. A higher floor surfaces names with a dominant, well-defined node rather than diffuse positioning.
  • Price — minimum spot price, useful for filtering out very low-priced names.
  • ER (Earnings) — include or exclude tickers inside an earnings window, so you can avoid — or specifically hunt for — event-driven positioning.

Confirmation Toggles#

Above the filters sit four confirmation toggles. Each one keeps only the tickers where that metric agrees with the direction of the #1 GEX node, so you can demand multiple independent reads before a name makes the cut:

  • IV — King-strike call IV vs. put IV direction.
  • P/C — put/call open-interest bias lines up with the node’s direction.
  • GEX — the GEX ratio (call share of total |GEX|) agrees with the bias.
  • V>OI — today’s volume already exceeds prior open interest at the relevant strike, a sign of fresh positioning.

Columns You’ll See#

  • Symbol — Ticker, with one-click links to its Heatmap and Chart.
  • Price / Chg% / Ext% — Spot, session change, and extension from a reference level.
  • ①Top % — Distance from spot to the #1 GEX node, signed (+ above, − below).
  • ①Strike — The strike price of the #1 node.
  • Confirmations — Quick badges for agreement with the #1 bias:
    • IV — King-strike call IV vs. put IV direction.
    • IV+ — King-strike call IV vs. spot-strike call IV.
    • P/C OI — Put/call open-interest bias.
    • GEX Ratio — Call share of total |GEX|.

OI, Vol, Vol > OI and P/C Ratio#

These four basics drive a lot of the Scanner's columns and confirmations:

  • OI (Open Interest) — outstanding contracts at a strike. The main driver of |GEX| magnitude.
  • Vol (Volume) — contracts traded today. High Vol relative to OI usually means fresh positioning.
  • Vol > OI — contracts where today's volume already exceeds yesterday's OI. A quick filter for brand-new activity.
  • P/C Ratio — put vs. call ratio (OI or volume, depending on context). Indices normally skew > 1 on OI because of structural hedging.

Sorting the Results#

Once the filters have narrowed the universe, sorting orders what’s left so the best candidates rise to the top:

  • Click any sortable column header to toggle asc / desc.
  • Sort by |①Top %| to find tickers closest to their strongest node — candidates for pinning behavior.
  • Sort by Ext% to surface stretched names.

One-Click Drill-Downs#

Every row has compact buttons that open the ticker's full Heatmap or Chart view in a new tab — useful for a quick visual check without losing your place in the scanner.
