Probably not unless you define a holiday list of your own in easy language,
one definition per stock exchange with different holidays that you trade, at
least there is not an easy way in TS100. There is a bug in the function
Businessdays.
My problem since the holidays has been that a system I have does not behave
as it should when holidays appears (like christmas eve). The code that goes
wrong can be simplified to:
if Date=juliantodate(BusinessDays(datetojulian(dateToBuy),2,-1)) then
buy next bar at pricetobuyat stop;
An easy way to test the code is placing it in an indicator with some
parameters:
Inputs: DateToBuy(990101),NumberOfShares(200),PriceToBuyAt(200);
if Date=juliantodate(BusinessDays(datetojulian(dateToBuy),2,-1)) then
Buy("PortfolioBuy") NumberOfShares contracts Next bar at PriceToBuyAt
stop;
Testing the indicator using dates preceded by nontrading days, and dates
preceded by trading days give erratic behavior on these nontrading days that
are special holidays.
Going through the traditional bug reporting procedure with Omega, I have
past all the mandatory stages from this not being reproducable to this not
being a bug to this not currently featured.
Their last stement is below:

> End;
Even though Omega claims the problem to lie within JulianToDate, it is very
clear that the bug they have in TS100 is in the function Businessdays, which
actually does not look at any holiday list at all.
