Monday, January 19 (Martin Luther King, Jr. Day) is a new exchange holiday. It
is not listed in the Omega Research Server Holiday List. Therefore, unless you
set up the holiday in the Holiday List, daily settlement prices for all domestic
exchanges from Friday, January 16 will be duplicated on all daily data based
charts on Monday, January 19. To ensure normal data collection, you will have to
set up the new holiday in the American Holiday List.
This document contains the following instructions:
A. How to set up the holiday in the Holiday List to ensure normal operation.
B. What to do after the holiday if you did not add the holiday to the Holiday
List.
C. Frequently asked questions pertaining to holidays in general.
A. How to setup the holiday in 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. Click Add Date.
5. In the Date field, type 01/19/98.
6. In the Description field type Martin Luther King, Jr. Day.
7. Click OK.
8. Click OK.
9. Click Close.
Note: You must set up the holiday by Sunday, 1/18/98 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 add the holiday to 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 01/19/98.
4. On the Daily line, set the End Date to 01/19/98.
5. Click Add by.
6. Highlight all DOMESTIC 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 foreign 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 domestic exchanges. Data collection from foreign exchanges
will not be affected.
