Syntax

public static DateTime DateOfNextTradingDay(this WealthScript obj, int bar)
public static DateTime DateOfNextTradingDay(this WealthScript obj, DateTime dt)

public DateTime DateOfNextTradingDay(int bar)
public DateTime DateOfNextTradingDay(DateTime dt)

Parameter Description

bar	Current bar number
dt	Current DateTime

Description

DateOfNextTradingDay returns the DateTime of the next trading day with respect to the bar number or date passed to the function. You can use this function to determine if the next trading day is a specific DayOfWeek (like DayOfWeek.Friday). This information can be used to trigger an Alert for a trading action on the next day, i.e., bar + 1.

The function is useful primarily for EOD strategies (Daily scale) but should also work for Minute, Second, or Tick scales too.
