Overview
On every bar, it evaluates execution context properties including historical status, real-time status, new bar creation, bar confirmation, and boundary conditions such as the first or last confirmed historical bar. The script constructs text labels above each candle listing all active states and applies color coding matching the primary bar condition to help developers visualize how Pine Script processes chart data.
- Bar state variable visualization
- Dynamic text labels above bars
- Color-coded execution context

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
