| Subject: Omega Research - American Holiday List - July 4th Update
|
|
| Dear Valued Customer,
|
| All customers trading Domestic Markets will need to edit the American
| Holiday List. The Independence Day holiday is listed in our Holiday List
| as July 4, 1998. This would normally be correct, except that this year
| July 4 occurs on a Saturday and the celebrated holiday is on Friday,
| July 3. Therefore, in order to prevent settlement (daily) data from
| Thursday, July 2 from being duplicated for Friday, July 3, all clients
| using TradeStation 4 or SuperCharts RT must change the holiday date in
| their holiday list. TradeStation 3.5 customers will be adding this
| holiday to the American Holiday List rather than editing this holiday.
|
| Below you will find a FAQ explaining how to edit the American Holiday
| List and make the appropriate changes. This document is also now posted
| on our Internet site at www.omegaresearch.com
|
| We will post this message again the week prior to Independence Day.

| 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.
