Transport controls — play, speed, rewind
Drive the tape: play and pause, change speed, skip or scrub through the day.
The replay bar runs along the bottom of the desk. It works like a video player, except the “video” is the real order book.

Controls
| Control | What it does |
|---|---|
| ▶ Play / Pause (Space) | Starts or halts the tape. Orders keep working while paused; nothing fills until the tape moves. |
| ⏮ 10s / 10s ⏭ | Skip back or forward ten seconds. Hold either button for 30s, 1m, 5m or a custom jump. |
| Speed | ½×, 1×, 2×, 5×, 10×. Changes apply live. |
| Scrub bar | Drag to any point in the day. The ET clock and % complete read out beside it. |
Rewinding with open orders
Rewinding is honest: the desk replays the tape from the earlier point, and your working orders are still working. A limit that would have filled on the way back through fills again.
Buffering
A BUFFERING badge appears while the desk fetches the next slice of tape. Playback resumes on its own.
