time_tradingday - Pine Script Variable

Overview

Section titled “Overview”

time_tradingday returns the timestamp for 00:00 UTC of the trading day that contains the current bar. This is especially useful on overnight markets where the session spans two calendar days.

Remarks

Section titled “Remarks”
  • Unlike time, this value always aligns to 00:00 UTC of the trading day, even if the session opens the prior evening.
  • On resolutions above "1D", the value corresponds to the final trading day captured inside the aggregated bar.
  • Useful for grouping bars by trading day or aligning session-based calculations across symbols.

Example

Section titled “Example”
//@version=6
indicator("Trading day comparison", overlay=false)


dayOfWeekExchange = dayofweek(time)
dayOfWeekTrading  = dayofweek(time_tradingday, "UTC+0")


plot(dayOfWeekExchange, "Exchange day", color=color.blue)
plot(dayOfWeekTrading, "Trading day UTC", color=color.teal)


bgcolor(dayOfWeekExchange != dayOfWeekTrading ? color.new(color.orange, 85) : na,
    title="Overnight session spillover")
