Overview
FunctionDatestring exports datetime, date_, and time_, each defaulting to the current time, and prefixes single-digit months, days, hours, minutes, and seconds with a leading zero. It draws nothing on the chart. A small DebugConsole demo queues sample strings on new bars and on the last confirmed history bar. There are no inputs, signals, or trading rules.
- Zero-padded datetime string
- Date-only string export
- Time-only string export
- Single-digit prefix helper
- DebugConsole sample output

Risk Notes
No repainting, lookahead or stacked entries were found in its code or README. That says nothing about how well it works: test it first.
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.
