Review Checklist

Critical Issues (Must Fix)

1. **Repainting Issues**

• `request.security()` without `lookahead=barmerge.lookahead_off`
• Using `close` instead of `close[1]` in realtime
• Future data leakage

2. **Syntax Errors (2025 Rules)**

• Ternary operators split across lines
• Wrong indentation on continuation lines
• `plot()` inside local scopes
• Loop boundaries not cached (March 2025 change)

3. **NA Value Handling**

• Operations on potentially NA values
• Missing NA checks before calculations

Warnings (Should Fix)

4. **Performance Issues**

• Multiple `request.security()` calls that could be combined
• Repeated calculations not cached
• Large arrays without size limits

5. **UX Issues**

• Inputs missing tooltips
• Inputs not grouped
• Not using `active` parameter for conditional inputs

6. **TradingView Limits**

• More than 40 `request.security()` calls
• More than 500 plots
• Arrays exceeding 100K elements

Best Practices

7. **Code Organization**

• UDT-first architecture for complex data
• Using `xloc.bar_time` instead of `xloc.bar_index` for drawings
• `for...in` loops instead of traditional `for` loops

8. **Strategy Requirements**

• Missing `//@strategy_alert_message` annotation, or placed before `strategy()` (it must come after the `strategy()` call)
• Missing `//@version=6` declaration
