?: - Pine Script Operator

Overview

The ternary operator evaluates a boolean condition and returns one of two expressions. It is useful for choosing a value inside another expression.

Syntax

condition ? valueWhenTrue : valueWhenFalse

condition must be boolean. The two result expressions must have compatible types; the returned value and qualifier follow Pine Script’s type rules.

Example

//@version=6
indicator("Ternary example", overlay = true)

color candleColor = close >= open ? color.green : color.red
barcolor(candleColor)

Chaining conditions

color timeframeColor = timeframe.isintraday ? color.red :
     timeframe.isdaily ? color.green :
     timeframe.isweekly ? color.blue : na

Remarks

The ternary operator returns a value; it does not create a local scope like an if structure.
It has the lowest operator precedence. Use parentheses when the intended grouping is not obvious.
Long chains are harder to review. Prefer switch when several named cases express the logic more clearly.
