Fix “Could not find function or function reference”

Replace the unknown call with a function that exists in the namespace and Pine version you declared. `ta.average()` is not a Pine Script v6 built-in, while `ta.sma()` accepts a source and length for this calculation. Check spelling, the `ta.` namespace, argument types, imported library names, and the Reference Manual before choosing a replacement. Similar names do not prove that two functions have the same behavior.

Root causes

  • The function name does not exist in the declared Pine version.
  • A built-in is missing its namespace, such as `ta.`, `math.`, or `request.`.
  • A library was not imported, its alias changed, or the function is not exported.
  • The intended replacement has a different signature or calculation.

How the fix was verified

Method
Pineify UAT grammar checker via check-pine-script-grammar.mjs
Broken result
Returned a missing-function diagnostic at line 3, column 17.
Fixed result
Returned no grammar diagnostics.
Limit
The replacement is correct for a simple moving average. A similarly named function may not preserve another script’s intent.
