How to specify a custom last bar for Pine Script indicator?

I want to find a way to tell the indicator that the last bar is at for example this date 2024-01-01 16:00:00 and plots the indicator. In other words I want to set the end time for indicator. And ignore data beyond that date for calculations.

Right now the current bar is always the last bar.

Solution

You can use a timestamp to define your end time and do all your calculations and plots when time < end time.

Here is an example:

//@version=5
indicator("My script", overlay=true)

end_time = timestamp("Jan 01 2024 16:00:00")
can_plot = time < end_time
val = can_plot ? close : na

plot(val, color=color.white, linewidth=3)

If you want to keep the last value of your calculation, use a var variable.
