What causes it

The if line ends in a colon, as it would in Python. Pine's if has no colon: the indentation alone marks its body.

The fix, compiled

Delete the colon at the end of the if line.

Prints the error at line 4

//@version=6
indicator("My script")
x = 0
if close > open:
    x := 1
plot(x)

Compiles with no error

//@version=6
indicator("My script")
x = 0
if close > open
    x := 1
plot(x)

The same mistake in Pine v5

Compiled as //@version=5, the same code prints, at line 4:

Extraneous input ':' expecting 'end of line without line continuation'

Syntax: lines, brackets and characters

Compiled on TradingView 23 October 2026. The checker above reads repaint and v6 migration patterns; TradingView's compiler is the final word on whether a script compiles.

Method and privacy

Method: The script loaded in the checker was compiled on TradingView's Pine compiler on 23 October 2026 as //@version=6, and printed this error at line 4; the fix below compiled with no error or warning. Names such as variables come from the example and will differ in your script.
