On the mobile app version, It is much helpful to have session breaks or day-change lines on the intraday weekly chart!

Since the 1-day intraday chart is not a true 24-hour chart (it starts plotting only when a day trading starts, and extends to the right during the day, it is not much helpful to compare with the previous day’s performance. The intraday weekly (5-day) chart is more useful for tracking the performance. And the day session break lines help to identify the day change.
