Hermes is an index and ETF market-structure workspace. It combines Quote Flow, dealer gamma, open interest, options analytics, Market Events, breadth, and Session Pulse briefings so the session can be read from one workspace instead of scattered tabs.

​
What these docs cover

This site focuses on how to read the analytics Hermes produces: what each view shows, what the inputs mean, and how to cross-check one tool against another. If you want infrastructure details, check the codebase in the repo instead.

Session Pulse

Learn how the scheduled SPY-focused briefings, special reports, and in-app panel keep market context continuous across the day.

Quote Flow

Learn how to read cumulative 1-second NBBO quote buckets, bubbles, profile panels, live mode, and replay mode.

GEX Analysis

How to use GEX Combined, GEX Ladder, GEX Interval, Net Drift, and Net Flow together throughout the trading day.

Chart Grid

Configure a multi-chart workspace with independent panels, synchronized crosshairs, saved dashboards, and per-panel settings.

Open Interest

Read SPY and SPX call/put positioning by strike, selected expiries, put-call ratio, max pain, call wall, and put wall.

Options Chart

Learn what the options chart page shows, how to compare strikes quickly, and how to review short-dated SPY and SPX contracts.

Options Chain

Use Chain Table and Chain Charts to scan calls, puts, expiries, strike behavior, and nearby contracts without flipping between broker tabs.

Market Context

Use Market Events, Market Overview, and Market Breadth to keep headlines, tape health, and structure changes near the chart.

Symbol Charts

Configure SPX, SPY, VIX, QQQ, NDX, DOW, RUT, and other chart panes with the overlays and session levels used in the dashboard.

Who this is for

Traders already comfortable with options basics (delta, theta, put/call spreads) who want better context around quote liquidity, dealer positioning, and session structure. You don’t need a math background — every chart page starts with plain-language explanations of what you’re looking at and what it means.
