Debug And Fix Pine Script
Paste TradingView errors and full scripts so Scribe Studio can repair them.
Scribe Studio is at its most useful when something is broken. Pine Script's compiler is strict, runtime issues like repainting are easy to miss by eye, and a single misplaced character can take an entire script offline.
Debugging Workflow
- Copy the full script. Not a snippet. Compiler errors often point at line 47 of a problem that started at line 12. Send the whole file so Scribe can see the variables, inputs, and series the failing line depends on.
- Copy the exact TradingView error. Word-for-word. Error text contains the function name, the line number, and the type mismatch — all of which Scribe uses to locate the fault.
- Paste both into Scribe. Use the debug prompt template below. State whether you want a minimal surgical fix or a full cleanup.
- Paste the revised code back into TradingView. Replace the editor contents, save, and click Add to chart again.
- Repeat in the same chat. Pine errors often cascade — fixing one exposes another. Stay in the same conversation so Scribe keeps the running context and remembers every change it has already made.
Send full scripts, not snippets
Less useful: "I'm getting an error on my crossover function — can you fix it?"
More useful: Paste the entire script, paste the exact error text, and say "fix this compile error and return the full corrected script." Scribe can see the full type chain, the inputs the variable depends on, and the actual function signature — and that turns a guess into a fix.
Debug Prompt Template
Fix this Pine Script code.
TradingView error:
[Paste exact error here.]
Code:
[Paste full script here.]
Return the corrected full script and briefly explain the cause.
Repainting Review Prompt
When a script uses higher-timeframe data or shows signals that appear and disappear, ask Scribe to audit it:
Please review this Pine Script for repainting risk.
Check the following:
- request.security() calls
- Lookahead settings
- Bar-close confirmation
- Any logic that could quietly use future data
Return a safer version if needed and explain what changed.
Common debugging mistakes
- Sending a screenshot of an error instead of the text. Exact error text is searchable; a screenshot is not.
- Sending one line of code when the error depends on variables defined elsewhere. Full scripts fix faster than snippets.
- Starting a new chat for each error in the same script. Each new chat is cold — stay in one conversation so Scribe keeps the full version history of your script.
