If no output is requested, plot the bollinger bands of the ASSET. If output is requested, return the values for the bollinger bands. If given, ALPHA is the weighting power of the moving average; 0 (default) is the simple moving average, see `movavg' for the full definition. WIDTH is the number of standard deviations to plot above and below the moving average (default: 2).

DIRECTION indicates the next day (default) if 1 and the previous day if -1. HOLIDAY is a vector of datenums that defines the holidays observed (the holidays function is used if not given). WEEKEND defines the days of the week that should be considered weekends; [1 0 0 0 0 0 1] (default) indicates that Sunday and Saturday are holidays. If any of the optional inputs (DIRECTION, HOLIDAY, WEEKEND) are empty, then the default is used.

SDATE is the starting date, EDATE is the ending date, both are in serial date format (see datenum). BDMODE is the business day frequency ("daily", "weekly", "monthly", "quarterly", "semiannual", or "annual"); these can be abbreviated by the first letter and they may also use an integer corresponding to the order in the above list (i.e. "daily" = 1). HOLVEC is an optional list of holidays. If the holidays are not given, then the holidays function is used.

Convert the current axis tick labels (or the axis handle H) to a date format. The axis given by AX ("x", "y", or "z") will be changed; the default is "x". The date format, DATEFORM, used will be either auto-determined or an integer corresponding to the date formats in datestr. If STARTDATE is given, then the first tick value on the given axis is assumed to be that date.

This routine tries to be as forgiving as possible to the date input while requiring that the date is not ambiguous. Anywhere possible where it would not be ambiguous, efforts were made to make times possible with seconds and AM/PM as optional. Also, along the same lines, where possible, commas were allowed with spaces, and the year/month/day separators were allowed as period (.), slash (/), and dash (-). Not all format possibilities are shown in the following table, but a date like `dd-mmm-yyyy HH:MM:SS' is parsed just as well as `d/mmm.yyyy, ,H:MM, AM'. Supported `date' formats include (the same as datestr): *Code* *Format* *Example* 0 dd-mmm-yyyy HH:MM:SS 07-Sep-2000 15:38:09 1 dd-mmm-yyyy 07-Sep-2000 2 mm/dd/yy 09/07/00 3 mmm Sep 6 mm/dd 09/13 10 yyyy 2000 12 mmmyy Sep00 13 HH:MM:SS 15:38:09 14 HH:MM:SS PM 03:38:09 PM 15 HH:MM 15:38 16 HH:MM PM 03:38 PM 17 QQ-YY Q3-00 19 dd/mm 13/03 20 dd/mm/yy 13/03/95 21 mmm.dd.yyyy HH:MM:SS Mar.03.1962 13:53:06 22 mmm.dd.yyyy Mar.03.1962 23 mm/dd/yyyy 03/13/1962 24 dd/mm/yyyy 12/03/1962 25 yy/mm/dd 95/03/13 26 yyyy/mm/dd 1995/03/13 27 QQ-YYYY Q4-2132 28 mmmyyyy Mar2047 29 yyyymmdd 20470313 30 yyyymmddTHHMMSS 20470313T132603 31 yyyy-mm-dd HH:MM:SS 1047-03-13 13:26:03 The parameter `P' is needed to convert date strings with 2 digit years into dates with 4 digit years. 2 digit years are assumed to be between `P' and `P+99'. If `P' is not given then the current year - 50 is used, so that dates are centered on the present. For birthdates, you would want `P' to be current year - 99. For appointments, you would want `P' to be current year. This function makes no strong attempt to verify the accuracy of the numbers that it returns in that it doesn't (currently) check to see that you're not trying to use the date Feb 30. When applicable, it tries to make your input work, though. It will try to determine if you're using the date "03/13/95" that the date is "March 13, 1995", but if there is doubt, datesplit will return an error instead of trying to guess the wrong value.

If both D1 and D2 are string matrices, then the number of rows must match.

FIELDS are the data fields to download and must come from the set * "Symbol" * "Last" * "Date" * "Time" * "Change" * "Open" * "High", * "Low" * "Volume" As an output, FIELDS may be different than your request. This is because there is mapping of field names from the data source to the output, and what is returned is the source mapping to allow validation. DATE is the date string or datenum for the requested data. If you enter today's date, you will get yesterday's data. FROMDATE and TODATE allow you to specify a date range for the data.

If set to 1 (Excel for Mac), CONVENTION specifies to use the Excel 1904 convention where Jan 1, 1904 corresponds to Excel serial date number 0. Note that this does not take into account the Excel bug where 1900 is considered to be a leap year unless you give the "ExcelBug" option. Excel does not represent dates prior to 1 January 1900 using this format, so a warning will be issued if any dates preceed this date.
