Market Replay ​

Replay historical candlesticks from a chosen starting point. Useful for backtesting, study, and education. UI only — no Chart API for replay.

Usage ​

  2. Click a candle on the chart to set the start point.
  3. Press Play to replay candles to the right of that point.
  4. Press Pause to stop, then Play again to resume.
  5. Press Live to jump to the end and return to real-time data.
  6. Press Close to exit replay and restore live updates.

Replay runs per chart. The control panel title includes the chart id (e.g. chart1).
