Pine Script v6 migration checklist

These lines don't compile in v6, or behave differently. Check each one (TradingView's guide).

Line 1: Script targets Pine Script v5 (current is v6)Caution
Line 1 declares //@version=5. Changing the header alone does not convert the script: v6 changed how bools, division, conditions and some strategy settings behave.
Fix: Convert it with the Pine Editor's built-in converter (TradingView's migration guide shows where), then work through the items listed here.

What causes it

A bracket opened on the line is not closed before the line ends. This is Pine v5's wording.

The fix, compiled

Count the brackets on the marked line and add the missing ). A call nested in another call needs one for each.

Prints the error at line 3

//@version=5
indicator("My script")
plot(ta.sma(close, 14)

Compiles with no error

//@version=5
indicator("My script")
plot(ta.sma(close, 14))

The same mistake in Pine v6

Compiled as //@version=6, the same code prints, at line 3:

Syntax error: Missing closing parenthesis

That message, with its own fix

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=5, and printed this error at line 3; the fix below compiled with no error or warning. Names such as variables come from the example and will differ in your script.
