Import data padding type
None - don't add any padding bars (this is the default and can be used most of the time)
AllMarketDays - add a padding bar for any market day in a symbol's date range where the symbol has no bar
AllWeekDays - add a padding bar for any weekday in a symbol's date range where the symbol has no bar (including holidays)
AllCalendarDays - add a padding bar for any date in a symbol's date range where the symbol has no bar (including weekends)
AlignWithSymbol - add padding bars that the PadAlignSym symbol has but this symbol lacks, and remove bars from this symbol that the PadAlignSym lacks
When Norgate is the data source, padding of any of the above types is provided by Norgate.
For other data sources, RealTest does the padding in the same way that Norgate does.
When data is imported for multiple markets that have different holiday schedules, "AllMarketDays" means any day where any of the included markets is open.
