Replay Mode
Study chart history one candle at a time, at your own pace.
Replay Mode lets you return to a point in chart history and watch the following candles appear in sequence. Use it to practice reading a setup, review how a move developed, or manually test a trade idea without starting with the full outcome visible.
Replay Mode is free in QuantCharts. Playback runs client-side, in your browser.
Start a replay
- Open the chart you want to review in QuantCharts.
- Select Replay from the chart controls.
- Choose a starting date or use the history slider to select a specific candle.
- Set the update speed, then start playback.
The chart advances from your chosen point, revealing the candles that follow it. Start before the setup you want to study so you can review the information available as it develops.
Choose a starting point
Select a start date when you already know the period you want to revisit. Use the history slider when you want to find a particular candle or move through the available chart history visually.
For example, start just before price reaches a level you are watching. Decide what would confirm or invalidate your setup, then play forward to see what follows. Choose another starting point to review a different occurrence.
Control playback speed
The update speed controls how quickly candles appear during playback. Open the speed dropdown in the toolbar, shown as a multiplier such as 1x or 5x. Use a slower pace to inspect individual bars or a faster pace to review a longer stretch of history. Use Play/Pause to start or pause playback.
Playback speed and chart timeframe serve different purposes: the timeframe determines what each candle represents, while playback speed determines how quickly the replay reveals those candles.
Floating or docked toolbar
The Replay toolbar can float over the chart or be docked/pinned.
- Floating: position the controls where they are convenient for the part of the chart you are reviewing.
- Docked/pinned: keep the controls in a fixed location while you follow the chart.
Use the toolbar's pin control to switch its placement.
Replay with multiple charts
Replay Mode supports multi-chart layouts. Open your layout, select Replay, choose the starting point, and set the update speed to review the charts together as playback progresses.
The number of charts available in a layout depends on your plan; Replay Mode itself is free.
