Sessions and time

Day Separator

A dotted vertical line at the start of each new trading day with alternate days faintly shaded, which keeps a long intraday chart readable when the chart's own session breaks are turned off.

What it will not do

  • The day boundary is the exchange's, not your local midnight, so on an instrument that trades overnight the day changes in the middle of a move.
  • TradingView keeps a limited number of drawings, so the oldest separators are dropped as you scroll further back.
  • Nothing is drawn on a daily or higher chart, where every bar is already a day.

Written from this description

Draw a vertical dotted line at the start of every new trading day on an intraday chart and shade alternate days faintly so each day is easy to separate by eye.
