Support for eSignal Data Retrieval

Datafeed Toolbox™ software now supports retrieving data from eSignal^®.

New blp Methods Return Information About Bloomberg V3 Connection

Three new methods for the blp function return information about the Bloomberg^® V3 connection:

• blp.category returns category information for a specific search string.

• blp.fieldinfo returns field information for a specific field mnemonic.

• blp.fieldsearch returns field information for a specific search string.

blp.timeseries Method Now Returns Total Value

The blp.timeseries method now returns an additional field, Total Tick Value, when returning Bloomberg V3 intraday tick data.

Support for Reuters Publishing

You can now contribute data to a Reuters^® datafeed with the new reuters.contrib method.

New rmdsconfig Function to Start Reuters Configuration Editor

You can now use the rmdsconfig function to start the Reuters Configuration Editor.

Reuters fetch Function Callbacks Now Require Three Inputs

In previous releases, the reuters.fetch function callbacks required two inputs. They now require three. The third input argument is the serviceName.

Compatibility Considerations

If you wrote code with the reuters.fetch function in R2010a, it will no longer work. Modify your callbacks to take a third input. Type help rtdemo at the command line to see an example.

Proxy Information No Longer Required for yahoo Function

In previous releases, if you wanted to connect to Yahoo!^® through a proxy server, you needed to supply your IP address and port number. This is no longer necessary. The yahoo function now uses the proxy information supplied in the MATLAB Web Preferences. To view or update your information, select File > Preferences > Web.
