Adjust nominal values of option orders

Orders on options were recorded inconsistently in old versions. For index options , the nominal value was calculated in contracts, for equity options in units. Posting and evaluation is now standardized in contracts. In this context, the old data must be cleaned up. This means that the nominal values for stock option orders must be divided by the correct contract size.

The database upgrade displays an informative message if there are orders for options, but does not change any data. After the database upgrade, the data status may therefore be incorrect and provide incorrect evaluation results. After the database upgrade, a data retrieval should first take place in order to import the contract sizes of current options into the database.

If you have carried out a data retrieval and read in the new data, proceed as follows to carry out a data migration and adjust the nominal values of the option orders:

On the "Data maintenance" tab, select the ADJUST OPTION FILE NAMED VALUES command in the "Data migration" icon menu.
The "Adjust nominal values of option orders" dialog box appears. After data analysis, a list of stock options for which orders exist is displayed.

Select the desired options and correct the data. In addition to manually entering the contract size directly in the list, for example, you have other options for managing the data via the main menu of the dialog box. Please read the following subsections.

The information and columns of the dialog window in detail:

Column	Description
Number of options selected	The total number of options currently selected.
Number of orders	The total number of orders for the currently selected options.
Number of errors	The sum of the column "No. Error" for the currently selected options.
Option	Name of the option.
Base paper	Underlying of the option.
	Activate or deactivate the checkboxes of the rows with the options that you want to select and edit further. You can delete or reverse the selection via the context menu, which you can open with the right mouse button.
	You should check the data for options in whose line this icon appears. The icon appears if the "Number of errors" column or the "Number of contract orders" column contains a value greater than zero.
Contract size	Enter the contract size here if necessary.
No. Orders	The number of orders.
No. Error	The number of orders whose nominal value is not a multiple of the contract size.
No. Kotraktorders	The number of orders whose cash flow does not correspond approximately to nominal value * order price, i.e. which have probably already been recorded on a contract basis.

Select the command START, SAVE ORDER VALUES... in the main menu of the dialog window "Par value adjustment orders on stock options".
Confirm the dialog box that appears with the confirmation prompt by clicking the "OK" button, then the nominal order values are scaled with the contract sizes and saved. Attention: This process cannot be reversed.
A message window informs you that the conversion was successful. Confirm this with "OK" as well.
Once the nominal order values have been saved, the options are marked with a lock icon.
