Version & syntax patterns
Flags missing declarations, v6 migration issues, legacy namespace patterns, and other high-confidence structural problems.

Find what broke.
See what matters.
Paste your TradingView Pine Script. Terrane checks structural errors, order paths, version problems, repainting and lookahead patterns, plus backtest assumptions—then separates what was actually detected from what needs semantic review.
01Deterministic first
Repeatable code checks before any AI interpretation.
02Evidence attached
Findings point back to the relevant source line when possible.
03No fake compiler pass
TradingView remains the authority on compilation and runtime behavior.

04Semantic reviewIntent mismatches and harder logic defects
Terrane will never label a script “compiled” unless TradingView actually compiled it.
What Terrane checks
A diagnostic, not a green-check generator.
The tool is designed to narrow the failure surface before you start randomly rewriting code.
Entry & exit paths
Checks whether a strategy can create orders, whether an explicit closing path exists, and whether script type matches order usage.
Lookahead & realtime drift
Reviews request.security(), lookahead patterns, tick recalculation, realtime-only branches, and other historical/live divergence risks.
Backtest assumptions
Surfaces execution settings, missing costs, slippage assumptions, and conditions that can make a historical test less representative.
Important boundary
Terrane does not replace TradingView's compiler.
Static analysis can identify many common failure patterns, but only TradingView can compile and execute the exact script against its Pine runtime and chart data. Use the exact TradingView error message when you have one—it makes the deep review substantially more precise.
