• Each line in the file must have the same or a higher date number than the line before it. Date numbers are six digits, YYMMDD, e.g. 201225 for Christmas Day 2020
• All lines that begin with a hyphen are treated as comments.
• Lines beginning with a # are also comments, but the lines are written to the message log when the file is loaded by Investor/RT at startup.
• Be sure to specify the date number in the format YYMMDD, last 2 digits of the year, 2 digit month, 2 digit day of month.

There are 4 possible line formats

• YYMMDD,H,holiday name  (The H means "all session" holiday).
• YYMMDD,session,holiday name  (session-specific holiday). session is a number from 0 to 99, the session number.
• YYMMDD,DB (the date daylight savings time begins in the U.S.)
• YYMMDD,DE (the date daylight savings time ends in the U.S.)

Note : to declare a session-specific holiday for 2 or more sessions, include lines for each session with the same date number.

Maintaining your own holidays calendar file - IMPORTANT NOTICE

The holidays.txt is updated every time you install a new version of Investor/RT. Do not make revisions to holidays.txt. If you do make revisions to the holidays.txt file, your revisions will be lost when you next update the software.

To supply your own holiday edits, save this file under the name myholidays.txt in your local admin directory.

At startup, the Investor/RT looks for myholidays.txt; if it is present, it is used instead of the holidays.txt file in the install directory.

If myholidays.txt does not exist in the local admin directory, holidays.txt in the install directory is used.

Place myholidays.txt into C:\Users\your-user-name\InvestorRT\admin\  This admin directory is your local admin folder, the "working directory" admin folder.
