Indicates whether this bar is the last bar of its month
Notes
Returns 1 for the last bar of a month, otherwise 0.
Note that this function operates on the unified date list for all symbols in the current data file by default, or the date list of the CalendarSym if specified.
To check whether the current bar is the last bar of the month for a specific symbol, use Month[-1] <> Month.
To work correctly when generating tomorrow's orders or using negative (future) offsets, a HolidayList should also be provided.
