LEVEL 4 · Building a Market-Study Workflow · LESSON 19
Market Replay / Playback
Use historical playback to learn platform windows, data, and practice workflows.
LEARNING OBJECTIVE
Locate Playback controls and distinguish replay from live data.
IN ONE SENTENCE
Playback lets supported historical market data run forward in time so platform windows can show the same period. It can help you learn the interface and review past exercises.
Basic concepts
Market Replay dataExplainClose
Recorded market events for playback. Availability and completeness depend on the instrument and date.
Historical Tick dataExplainClose
Historical data replayed one Tick at a time; its detail may differ from Market Replay data.
Software walkthrough
Menu placement may vary by platform version. Use the current official guide when a label differs.
