# Pine Script Development **Verify before implementing**: For Pine Script version-specific syntax or new built-in functions, look up current docs via Context7 (`query-docs`) before writing code. TradingView updates Pine Script frequently and training data may be stale. ## Critical Syntax Rules - **Ternary operators MUST stay on one line** -- splitting across lines causes "end of line without line continuation" error. For complex ternaries, use intermediate variables: ``` isBull = close > open barColor = isBull ? color.green : color.red ``` - **Continuation lines outside parentheses MUST be indented by a non-multiple of 4** -- same indentation as the start errors, and 4/8/12 spaces parse as a local block and error too (2 spaces is the conventional choice). Inside parentheses (function calls, parenthesized expressions) any indentation works, including multiples of 4 - **NEVER use plot() inside local scopes** (if/for/functions) -- use conditional value instead: `plot(condition ? value : na)` - **barstate.isconfirmed** -- use to prevent repainting on real-time bars ## Platform Limits 500 bars history for `request.security()` | 500 plot calls | 64 drawing objects | 40 `request.security()` calls | 100KB compiled size - Drawings positioned with `xloc.bar_index` reach at most 9,999 bars into the past and 500 into the future; for anything older, switch the drawing to `xloc.bar_time` and pass a timestamp (a time value without `xloc.bar_time` is treated as a future bar ind...
