Description
Static analysis tool for Pine Script repaint detection on TradingView RepaintChecker analyzes the source code of Pine Script indicators on TradingView and flags patterns that commonly cause repainting — so you can spot misleading "perfect signal" scripts before you trust them on a live chart. WHAT IT DETECTS - security() calls without barmerge.lookahead_off - Future-leaking lookahead patterns - Realtime-only branches (barstate.isrealtime / isconfirmed misuse) - request.* calls with risky parameters - Other heuristics drawn from the Pine Script community's repaint catalog HOW IT WORKS - Open any Pine Script indicator's source on TradingView - Click the RepaintChecker icon — analysis runs in your browser in milliseconds - See a verdict (High / Medium / Low risk), a score, and a list of detected patterns with line references PRIVACY - 100% local analysis. Source code never leaves your machine. - No account required. - No tracking, no ads. - Optional email signup for updates only. LIMITATIONS RepaintChecker uses static code analysis. It cannot guarantee runtime behavior, and not every repaint pattern is detectable from source alone. Results are informational only and are NOT investment advice. See our Terms of Service for details. RepaintChecker is a free tool by Pinary — tooling for serious Pine Script developers.
