Frequently Asked Questions

ta.tr is a built-in series that holds the true range for each bar: the maximum of the bar range (high − low) and the absolute gaps from the prior close to the current high and low.

The variable behaves like ta.tr(handle_na = false). The function ta.tr() lets you set handle_na to change behavior when the previous close is na.

Use ta.tr when the default na behavior matches your script. Use ta.tr(handle_na) when you need to control how missing prior closes are handled.
