Hello all,
The following is cut from the Omega web site.
I'm about two weeks behind reading digests, so this may have been posted
already, although a quick scan of all subject lines to date didn't turn it up.

Changing Independence Day in the American Holiday List
Independence Day (July 4) occurs on a Saturday in 1998. Therefore, Friday,
July 3, 1998 will be the celebrated holiday and the American markets will
be closed. The holiday is incorrectly listed in the Omega Research Server
Holiday List as July 4, 1998. Therefore, unless the holiday is changed in
the Holiday List, all exchanges in the Symbol Portfolio that are closed
will collect the daily settlement prices from Thursday, July 2 again on
Friday, July 3. To ensure normal data collection, you need to change the
holiday in the American Holiday List.
This document explains:
A. How to change the holiday to the Holiday List.
B. What to do after the holiday if you did not change the holiday in the
Holiday List.
C. Frequently asked questions about holidays in general.
A. How to change the holiday to the Holiday List:
1.In the Omega Research Server, use the Tools - Holiday Setup menu
sequence. 2.Highlight American Holidays. 3.Click Edit List. 4.Highlight
07/04/98 Independence Day and click Edit Date. 5.In the Date field, type
07/03/98. 6.Click OK. 7.Click OK. 8.Click Close.
Note: You must set up the holiday by Thursday, 7/2/98 11:59pm. If it is
not, you will need to perform Step B on the day after the holiday.
B. What to do after the holiday if you did not change the holiday in the
Holiday List:
If you did not add the holiday to the Holiday List prior to the holiday,
the server will collect daily settlement prices for the holiday, which will
simply be a duplication of the previous day's settlement prices. Therefore,
you will need to delete the daily data for the holiday. To do so:
1. In the Omega Research Server, use the File - Delete menu sequence.
2. Remove the check next to Intraday.
3. On the Daily line, set the Start Date to 07/03/98.
4. On the Daily line, set the End Date to 07/03/98.
5. Click Add by.
6. Highlight all affected exchanges (Hold down the CTRL key while clicking
the exchanges).
7. Click OK.
8. Click OK.
9. In the "Delete data?" dialog box, click Yes.
C. Frequently asked questions about holidays in general:
Q: Why is there a Holiday List?
A: Our server is scheduled to collect daily data after the close of each
market on the days scheduled in the symbol/exchange universe. All of our
compatible data feeds will continue to send the previous business day's
daily prices (also known as refresh, settlement, or daily data) during the
holiday. If a regularly scheduled day is a holiday (or non-trading day) and
the holiday is listed in the Holiday List, the server will not collect this
duplicate daily data. However, if the holiday is not listed in the Holiday
List, the server will collect the same daily data two days in a row.
Obviously, this will alter any technical analysis, which is why it is
necessary to either a) setup the holiday in advance or b) delete the
duplicated daily data after it has been collected.
Q: What other problems can I expect on the day after the holiday?
A: Your intraday and/or daily charts might contain gaps, which can alter
results of any technical analysis. For example, when calculating a trend
line, you should not include days with no trading.
Q: How can I fix this "time gap" problem?
A: From the TradeStation or SuperCharts main menu, use the Tools - Options
menu sequence. Click on the Price Data tab. Clear the checks from the first
two check boxes in the dialog box and click OK. This removes all of the
gaps on every intraday and daily chart on every workspace.
Q: Doesn't that throw off my trend line analysis if there really is a time
gap that's not due to the holiday?
A: Yes. However, most traders aren't too concerned about this because
trading (most of the time) is constant throughout the day.
Q: What about people who trade international markets that are open on the
holiday?
A: When you follow the directions in this document, you are only altering
the Holiday List for the affected exchanges you specify. Data collection
from other exchanges will not be affected.
