Overview
PSMC - Alerts Within Session defines a main trading session along with optional pre-market and after-market periods. The InSession function checks whether the current bar falls inside the session using time functions. Bar color changes based on session status to visually mark the bars. Alert conditions fire only when the bar meets the session criteria, either restricting alerts to within the session or enabling them outside after-hours. Input settings let users customize the exact session times. The script draws bar colors directly on the price chart and demonstrates session-based filtering for alerts. It relies on current bar data only.

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.
