LEVEL 4 · Building a Market-Study Workflow · LESSON 19

Market Replay / Playback

Use historical playback to learn platform windows, data, and practice workflows.

Written lesson
A study log only, not a skill check.

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 dataExplain

Recorded market events for playback. Availability and completeness depend on the instrument and date.

Historical Tick dataExplain

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.

  1. 01

    Step 01

    Connect to Playback from the Control Center and check that data is available for the selected date.

    Check: Confirm time advances with replay; the data is not live.

  2. 02

    Step 02

    Begin at a slow speed and observe the chart, linked windows, and playback controls.

    Check: Confirm time advances with replay; the data is not live.

  3. 03

    Step 03

    Record the data type, date, and study questions in your notes; replay results do not predict future outcomes.

    Check: Confirm time advances with replay; the data is not live.

Concept diagram

Concept illustration for education; it contains no live or historical market data.

Study scenario

Choose an available historical date and practice pausing, resuming, and changing speed.

Historical playback can differ from a live environment in data detail and execution behavior.

Common mistakes

  • Issue: No replay coverage for the date.

    Check the input, version, session, data, or setting that controls this behavior.

  • Issue: Treating replay as live data.

    Check the input, version, session, data, or setting that controls this behavior.

Lesson summary

  1. 01

    Replay uses available history.

  2. 02

    Coverage varies by source.

  3. 03

    Use it to practice software workflow.

PRACTICE EXERCISE

Record chart-time changes; consult the guide if data is unavailable.

Use static, historical, or browser-local sample data only.
