# Pine Script Development

**Verify before implementing**: For Pine Script version-specific syntax or new built-in functions, look up current official docs before writing code. Prefer Context7 (`query-docs`) when available. Otherwise use available web tools to read the [TradingView Pine Script docs](https://www.tradingview.com/pine-script-docs/) for the script's version. TradingView updates Pine Script frequently and training data may be stale.

## Critical Syntax Rules

- Keep simple ternaries readable; multiline expressions require valid continuation indentation. 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)`
- Use `barstate.isconfirmed` when signals require the chart bar's closing values. It does not establish that requested higher-timeframe values are confirmed; inspect `request.security()` offsets and lookahead separately.
