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 floating replay bar on the chart (once in replay, the top status shows REPLAY). The bar floats by default and can be dragged anywhere on screen rather than occupying fixed chart real estate; the Options Desk replay bar is floating and draggable too.
Replay and live never contaminate each other. Once you enter replay, historical frames feed the replay view only; the live stream keeps advancing independently in the background, and leaving replay returns you to the present with no stale frames mixed into the live series.
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. The bar stays expanded and repositionable, and never auto-collapses on hover.
All-window sync vs live-only windows
In the Options Desk, windows fall into three classes:
| Class | Windows | Behaviour in replay |
|---|---|---|
| Synced replay | Main chart, Tactical, Vol Intelligence, Vol Curve, GEX Data Center, Market State, Strategy Workshop, Cross-asset Matrix, Distribution Compare, Symbol Center, Level Recon | Replayed frame by frame off the master clock |
| Cursor-synced | Exposure Flow, Live Flow | Fetch the nearest historical frame for the master cursor and fill in progressively |
| Live only | Everything else (morning brief, portfolio, backtest, dark pool, order flow and so on) | Show a frozen overlay and sit out the playback |
A replay-capable window with no ticker bound falls back to a default instrument so the master clock can always start — which is why entering replay never leaves the whole screen stuck on "loading".
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 Live Flow 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 main chart draws price as a line, candles or Heikin-Ashi, across timeframes from 30 seconds to one day, with the 30-second micro bucket limited to ES/NQ. Bull-bear colour schemes (blue-up/gold-down or classic green-red) are switchable.
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.
