Overview
New 30 Min Bar defines a helper that reads the time of a given resolution and returns true when that time is valid and differs from the previous bar. The script calls the helper with a 30-minute resolution and plots 1 when a new bar begins and 0 otherwise. There are no user inputs; the resolution is fixed in the code. It draws in a separate pane. It does not generate trade signals or manage exits.

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.
