Sessions and time

Time Left on Bar

A corner table counting down the time until the current bar closes, which takes the guesswork out of waiting for a candle to finish instead of acting halfway through it.

countdown = str.format_time(int(msLeft), "HH:mm:ss", "UTC")

What it will not do

The countdown only updates when a new tick arrives, so on a quiet symbol it sits still and then jumps several seconds at once.
It is meaningful only on the last bar in real time. On historical bars the close time has already passed and the reading is zero.
On weekly and monthly charts the time remaining exceeds a day and the clock display wraps, so read it on intraday charts.
Waiting for a bar to close is a choice about your own process. The countdown says nothing about what price will do next.

Written from this description

Show a small table in the corner with the time and the seconds remaining until the current bar closes, and colour the countdown once it drops under a chosen number of seconds.
