Vision Portfolio Management Application Layer: Data Feeds
Data Feed: IndexAccountMaster
Category: MasterFeed
Summary:
-
The IndexAccountMaster feed is used to create and refresh
basic information for IndexAccount instances. An index account
is an Account whose holdings are created
starting with a list of securities that can be explicitly
provided or derived from a Universe.
The IndexAccount class is described in detail in the
Portfolio Management Application
Classes document. A number of related feeds
are available
to update and derive IndexAccount holdings
and to update other account-based information.
Available Fields:
| Field | Vision Property | Type | Description |
|---|---|---|---|
| --- Required Fields --- | |||
| entityId | code | String | id of new or existing IndexAccount instance |
| --- Suggested Fields --- | |||
| currencyId | baseCurrency | String | id of existing Currency instance |
| name | name | String | descriptive name |
| --- Other Fields --- | |||
| numericCode | numericCode | Number | numeric code |
| shortName | shortName | String | short name |
| sortCode | sortCode | String | sort code |
Special Processing Rules:
- The entityId is the unique id that permanently identifies the
IndexAccount. When a new IndexAccount is created, this field is used to
update the code property of the new instance. This id is also
added to the Named IndexAccount naming dictionary. It is
added to the Named Account dictionary if the id does not
conflict with the id of an instance from a different subclass of
Account. If a Portfolio instance is later created
with the same id as an existing IndexAccount, the reference
in the Named Account dictionary will return the Portfolio
instance.
- To distinguish IndexAccount instances from instances of other
Account subclasses that may be identified with the same id,
a unique identifier is created by prepending the string I_
to the entityId. This id is used to update the uniqueId
property of new IndexAccount instances and is added to the
Account naming dictionary as well.
- The currencyId is used to identify the currency in which monetary values for the index account are displayed by default. This includes the totalMarketValue and the totalMarketValueCash values for the IndexAccount as well as the totalMarketValue for its individual holdings. The default value is US Dollars.
