Supported FX Feeds
Currency Server can load currency exchange rate data in a
variety of data formats and transmission protocols, supporting
major official and free data feeds,
as well as commercial and subscription-based
services. Automatic updates of non-exchange rate data (such
as currency names and codes) are
also supported, and are covered in the
Currency World Monitor section.
Software Setup
To choose a provider of exchange rate data
open the FX Servers tab of Currency Server Manager and add or
edit a server. If you are running the Enterprise Edition of
the software, or if you added the
Multiple FX Servers option to the Standard Edition of
the software, you
can also choose more than one server, and decide what to do
with data from multiple servers (e.g. aggregate or
cross-check the data, or use backup servers for failover
purposes).
Types of Feeds
In practice, the exchange rate data feeds supported by
the software can be grouped into three categories:
- Public and official feeds (free)
- Commercial feeds (subscription-based)
- Aggregated feed by Currency System (free to software
customers)
A choice you may have to face is whether to
use free and official exchange rate data, or if instead you
should subscribe to a commercial service, which may offer data
for more currencies. The following text may help you:
Since most providers supply a higher number
of currencies than is practical for general purpose applications,
we recommend to lock the list of currencies in the Active Currencies
tab after a careful selection. The following article contains
more information:
The following sections describe some of the
FX feeds
which are supported by Currency Server. For additional information
concerning subscription options, terms of use and more details
about the currency data please refer to the respective
provider (e.g. by clicking the Web Information link
in the Add/Edit Server dialog of Currency Server Manager).

Becoming a Data Provider
When Currency Server collects data, it acts as a client.
When it offers exchange rate information and currency server
functionality to COM and Web service clients or
writing to a file, it acts
as a server.
Currency Server includes features which make it possible
to extend the server functionality well beyond the standard
programming interfaces. For example:
- Post-update modules can be set up to write or upload
exchange rate data files in XML, JavaScript, INI, CSV,
HTML and other formats.
- Custom validation modules make it possible to offer
a subscription-based Web service (you decide who can access
is, and how frequently)
- Deployment as part of multiple-server clusters (with
central administration and monitoring)
- Deployment as a server to feed data to customized currency
calculator clients (e.g.
WorldCalc
and
Euro Calculator)
