I'm trying to scheudle a function to run on the last trading day of every month. I see that there is a DateRule for MonthStart, but not one for MonthEnd. I see that there is the NthLastBusinessDay method, but I'm having trouble getting that to run correctly. Any tips?
Thank you!

You can make use of the TradingCalendar
Check the following example:
First you use a Schedule with a DateRules.MonthStart() and set the last tradeable day in a field.
Schedule.On(DateRules.MonthStart(), TimeRules.At(0, 0), () => { var monthLastDay = new DateTime(Time.Year, Time.Month, DateTime.DaysInMonth(Time.Year, Time.Month)); var monthTradingdays = TradingCalendar .GetDaysByType(TradingDayType.BusinessDay, Time, monthLastDay) .ToArray(); monthFirstTradableDay = monthTradingdays.First().Date; monthLastTradableDay = monthTradingdays.Last().Date; });
Then in another Schedule you will call every day you will check is the last traedable day in the month.
Schedule.On(DateRules.EveryDay(), TimeRules.At(16, 55), () => { if (Time.Date == monthLastTradableDay) { // Do Stuff } });
Hope it helps!

JayJayD thank you very much for the code sample!
I am trying to write this in Python, but am getting tripped up in working with the object returned by GetDaysByType. Is there any sort of documentation on using LINQ and Python?
JayJayD
I almost don't know the Python port, but I guess you can check what type returns the TradingCalendar and use the usual Python syntax:
e.g.: if TradingCalendar returns a List just use:
month_first_tradable_day = monthTradingdays[0].Date; month_last_tradable_day = monthTradingdays[-1].Date;

Here's my solution in Python. The type returned by TradingCalendar is not a list; I didn't spend too much time figuring out how to use the LINQ object returned, but iterating over it with a standard foreach Python loop did the trick.
def Initialize(self): self.Schedule.On(self.DateRules.EveryDay('SPY'), self.TimeRules.At(0, 0), Action(self.ScheduleEndOfMonthRebalance)) self.Schedule.On(self.DateRules.EveryDay('SPY'), self.TimeRules.BeforeMarketClose('SPY', 5), Action(self.Rebalance)) def ScheduleEndOfMonthRebalance(self): month_last_day = DateTime(self.Time.year, self.Time.month, DateTime.DaysInMonth(self.Time.year, self.Time.month)) trading_days = self.TradingCalendar.GetDaysByType(TradingDayType.BusinessDay, self.Time, month_last_day) #get the last day in trading_days for x in trading_days: self.month_last_trading_day = x.Date.date() def Rebalance(self): if self.Time.date() == self.month_last_trading_day: self.Debug(str(self.Time) + " | last trading day of the month")

Nice solution =)

Is it possible to use the Schedule function for a daily resolution backtest?
