Pine Script Development

Verify before implementing: For Pine Script version-specific syntax or new built-in functions, search current docs via search_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 MUST be indented MORE than the starting line -- same indentation = error
• 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
