Crosshair Syncing in Punch Split Charts

When you hover on one chart in split view, the crosshair appears on all other charts at the matching time.

How crosshair sync works

Comparing price action across multiple instruments or timeframes is much easier when you can line up the exact same moment on every chart. Crosshair sync does this automatically — drag on one chart, and every other chart in the split jumps to the matching timestamp.

Using crosshair sync

  1. Open a chart and switch to split view.

  2. Tap and hold on any candle to bring up the crosshair.

  3. Drag across the chart — every other chart in the split updates in real time, snapping to the candle that contains your selected time.

How it handles different timeframes

If your charts use different timeframes, Punch finds the candle that was "in progress" at the time you are hovering. It always rounds backward — to the candle whose start time is at or before your hover time, never forward to the next one.

For example, if you hover at 10:25 on a 5-minute chart and your second chart is set to 30 minutes, the crosshair snaps to the 10:15 candle on the 30-minute chart because that candle runs from 10:15 to 10:45.

Examples

30m

10:15

30m chart at 14:15

45m

13:45

30m chart at 14:15

5m

14:15

15m chart at 9:30

10m

9:25

Good to know

  • Crosshair sync is always on in split view. There is no toggle to disable it.

  • The sync always rounds backward to the candle in progress, never forward.

  • All timeframe calculations are anchored to 9:15 AM (NSE market open).
