Hermēs DocumentationReplay System
Replay takes HuntingFlow back to any historical trading moment and replays that day's GEX structure and price evolution at 1× to 30× speed, for reviewing how key levels played out and how regimes flipped.
The Replay System takes HuntingFlow back to any historical trading moment and replays that day's GEX structure and price evolution at 1× to 30× speed. It is a powerful review tool — see clearly "how a wall was tested/broken at the time" and "the moment a regime flipped".
Entry: the replay bar at the bottom of the main chart (once in replay, the top status shows REPLAY).
Panel walkthrough
Pick a day
Choose a tradable day from the calendar (only days with data are listed) to jump there and start replay.
Playback controls & speed
Play / pause, speed 1× – 30×; use the session scrubber to drag to any moment of that day.
Keyboard shortcuts
Space play/pause, arrow keys step back/forward, Esc exit replay. (Since v1.8 the replay bar stays expanded and no longer collapses on hover.)
All-window sync vs live-only windows
In the Options Desk, replay syncs these windows: main chart, Tactical, Vol Intelligence/Curve, GEX Data Center, Market State, Strategy Workshop, Correlation Matrix. Live-only windows (Live Flow, Option Chain, UOA Scanner, Morning Brief, Session Recaps, Portfolio, Backtest, Cross-asset Correlation) show a frozen overlay during replay and do not participate in historical playback.
Typical workflow
- Enter replay after the close and pick today on the calendar.
- Run through quickly at 2×–5×, pausing where key levels are tested/broken.
- Step with arrow keys to watch how GEX structure and 0Γ change around events.
- Cross-reference Market Review for how key levels played out, and log takeaways in the Trading Journal.

Frequently asked questions
What can replay play back?
Replay replays the price and GEX-structure evolution of a historical moment; in the Options Desk, the main chart, Tactical, Vol, GEX Data, Market State and Strategy replay-capable windows sync, while live-only windows like Option Chain, Live Flow and UOA freeze during replay.
What speeds and controls does replay support?
1× to 30× speed, a calendar to pick tradable days, play/pause and timeline scrubbing, plus keyboard shortcuts (Space play/pause, arrow keys step, Esc exit).
What subscription does replay need?
Replay is a shared feature of the main chart and Options Desk; the replay-capable tickers and history depth depend on your data tier.
Chart Modes & Timeframes
The HuntingFlow main chart supports line, candlestick and Heikin-Ashi drawing modes and switchable timeframes; the 30-second micro timeframe is available for ES/NQ only, with 1-minute to 1-hour elsewhere.
Voice Squawk
Voice Squawk reads out HuntingFlow's key structural events aloud, so you hear zero-gamma, walls, regime shifts and other anomalies the moment they happen without watching the screen — filterable by event type, with adjustable volume and English/Chinese voice.
