+// ---------------------------------------------------------------------
+// Determines whether the current time is inside a defined trade session.
+//
+// Parameters:
+// - t1              : Start time string (e.g., "22:00").
+// - t2              : End time string (e.g., "01:00").
+// - time_zone       : The timezone of input times (default = "Broker").
+// - plot_range_inp  : If true, draws vertical lines for start/end.
+//
+// Returns:
+// - true if current time is within the session window, false otherwise.
+//
+// Logic:
+// - Handles overnight sessions (e.g. 22:00–01:00) correctly.
+// - Automatically rolls the window to the next day when expired.
+// - Uses TimeZones class to convert time to broker timezone.
