Pine Script debugging
Fix Pine Script errors with diagnostics you can review
Bring the failing source and exact error to Pineify’s Coding Agent. Ask for a correction and a syntax check, review what changed, then verify the final script in TradingView.
Open Coding AgentA repeatable debugging workflow
Step 1
Capture the failure
Keep the source version, exact error message, highlighted location, symbol, timeframe, and steps that trigger the problem. Say what should happen instead.
Step 2
Request a focused correction
Ask the Coding Agent to explain the diagnostic and change only what is needed. Keep an original copy so you can inspect the proposed differences.
Step 3
Explicitly request the syntax check
Ask Pineify to check or fix syntax errors in the current code document. Inspect the returned diagnostics. After a revision, request a check on the final source again.
Step 4
Verify behavior in TradingView
Add the final script to the intended chart. Check plots, alerts, and strategy orders against your specification, including the bars where the original failure occurred.
Match the check to the failure
- Compilation diagnostics
- An invalid reference, argument, type, or scope can prevent compilation. Use the exact diagnostic and surrounding source to investigate; a later error may be a consequence of an earlier one.
- Runtime errors
- A script can compile and fail while executing. Reproduce the chart conditions and inspect the operation that fails. A clean syntax result does not resolve a runtime failure.
- Unexpected signals or trades
- Valid code can implement the wrong rule. Compare the conditions, signal timing, and order handling with your specification; do not use compilation as proof of strategy performance.
See TradingView’s error overview for error categories and its v6 migration guide for version changes. Keep migration separate from a minimal bug fix unless you intend both.
Frequently asked questions
Does Pineify automatically check every generated script?
No. Ask the Coding Agent to check, verify, or fix syntax errors in the current document. Generation and editing do not automatically trigger the syntax-check tool. Inspect the tool result for the version you intend to use.
Does a successful syntax check mean the script is correct?
No. A syntax check cannot establish that your trading rules, signal timing, position sizing, or results match your intent. TradingView also distinguishes compilation errors from runtime errors. Review the source and test the final script on the intended chart.
Can an AI fix change my indicator’s behavior?
Yes. Changes to types, scope, history references, calculations, or version-specific behavior can change the result. Ask for a focused patch and an explanation, then compare inputs, outputs, signals, and orders with your expected behavior.
Can Pineify help with an existing script?
Provide source you are allowed to use, its Pine version, the exact diagnostic, and the behavior you expect. Include accessible dependencies or explain what is missing. A script whose source or required library is unavailable may not be reproducible.
Is migration to Pine Script v6 the same as fixing an error?
No. Migration is a separate task with version-specific language and behavior changes. State whether you want to keep the existing version or migrate, consult TradingView’s migration guide, and validate the resulting behavior.
What if the check fails or times out?
Treat the source as unverified. Review any returned diagnostic, retry when appropriate, or reproduce the issue in TradingView’s Pine Editor. A service error or timeout is not evidence that the script passed.

For a specific message, visit the Error Lab. For an existing script, open the agent and describe the failing behavior. Access and usage depend on your current plan.
