code for automatic data retrieval from source

Hello,
I use Eviews 8. I would like to setup a code to create and later be able to update series from source. For instance, I heard that Eviews "communicates" with Haver Analytics. I was wondering if it is possible to set up with Moody's Analytics' Databuffet.com or Reuters' Datastream? I would like to create a code which would automatically pull updates into Eviews.
Thanks.

Yes, we have built in support for Datastream, and Moody's Economy.com data. Both require the Enterprise version of EViews, and an account with the data providers.
You can use the fetch command to fetch data from those providers into your EViews workfile.

Thanks, I have to check if I have enterprise version. with Fetch command - do I use moody's economy.com mnemonic for the series?
I have just looked up fetch command in help section - it does explain how to get data from database, but it does not explain how to get from outside data provider (moodys). Could you provide more info on that or tell where I could read more about it? Thanks

The easiest way to do it is to register your Moody's account in the EViews database registry, then use the fetch command to fetch from the name you've given that database. You can read all about the database registry in User Guide I.

Hi, So we upgraded Eviews 8 to enterprize edition. When I go to Database registry entry window and select Database/file type as Moody's economy.com and specify the path and alias, the user name and password field is greyed out - I cannot enter my user and password? Is there something that I am missing?

EViews will read Moody's Economy.com database files. These are local or network accessible (*.fdb) files. From what we gather, these files do not require a password or username. EViews currently does not support the download of Moody's data directly from their web servers (EViews does however support Datastream web server data retrieval). To use Moody's data you would have to first obtain the latest *.fdb files and fetch the data from there.

Do I need to obtain (*.fdb) files from Moodys?

Hi Jason,
I am a new Eviews 8 user and I try to work with both Eviews and Datastream. The "fetch" command to import my series directly from Datastream to Eviews worked well. I was wondering if there is a command to fetch the entire "Name" of the Datastream series directly to Eviews as well?
Many thanks!

If you open the downloaded series from within your workfile and then select view->label, you should see the original name in the history section

Great, many thanks! Is there any possibility, in a program, to assign the description/name of a series to the graph of the same series, as a title for example (addtext? or graph.label...?) ?
Thanks!!

Set the displayname of the series to the text you want to use in the graph.
