This thread is about the GetExchangeData add-in that provides an easy way to download historical exchange rate data into EViews.

Even though the top 21 currencies are currently avaiable, you can add a new currency by editing the program.
In particular, when you open the program GetExchangeData.prg, you will see the following two lines: Now suppose that you want to download the exchange rate between the US Dollars and the Argentine Peso.
By filling the last element of %currency_list and %currency_code with "Argentine Peso" and "ARS", respectively, you can download the series of interest. *Note that "Argentine Peso" and "ARS" should be in the same order as each other.

• 2011/02/11 Able to retrieve the data with more than 500 observations

Hi there:


It seems like to get the identical data series when the requested sample is larger than 500.

Thanks for your consideration.

It seems like to get the identical data series when the requested sample is larger than 500.

I am sorry that I do not get your question. Can you tell me more about your "identical series"?

As you know, when a currently active workfile has the series of interest (say "UDS2EUR"),
you will see the identical series with a different name (i.e. "USD2EUR01").

Hi Esther:

Eviews will obtain the FRX data series matching with the chosen currency when data numbers are no more than 500.

When data numbers equal to 501, Eviews will report the error message, Sorry, couldn't create table, because you entered incorrect dates....

When data numbers set to be more than 501, Eviews will obtain the identical series with different series name no matter which currency you choose.

In the three different time interval, for example, data numbers <500, =500 and >500 respectively, let Eviews retrieve two FRX data series, say usd2eur and usd2jpy, together in each time interval.

Both data series will be they should be when data numbers no more than 500.
It will get the mentioned error message showed in the data series when data numbers equal to 501.
Both data series will be identical when data numbers set to be more than 501.

Thanks for your patience and consideration.

I fix the problem. You can reinstall the updated "GetExchangeData" add-in.

Thank you.

Hi Esther:

Many thanks for your quick responses and admirable efforts.

The fixed version works like charm except for the data numbers set to be just equal to 501.

Best Regards,
MantaRay

Thank you for your valuable comments. The new version will allow you to retrieve the data with >500, including 501 observations.

Hi Esther:

The attached please find the available information regarding the issue.

Regards,

Try re-downloading the add-in.

Dear Gareth:

Many many thanks for your excellent job.

The issue finally gets resolved in the second revised version.
It now works great without any problem.

Best regards,

Thank Esther not me :D

Glad to see you're getting use out of the add-in anyway.

Sure, thank both of you, Gareth and Esther. :D

Hi EViews-team,

one of our customers just asked for a bug-fix in this addin. As it seems the addin fails when you want to update an exchange rate in an existing workfile. I got the feeling that something with the import command might have changed with eviews8 because getting the exchange-rates in a new workfile works for me.

Is there a solution available for the problem?

Thanks in advance!

Could you provide more details, or, possibly, an example?

Hi Gareth,

now I was able to figure out where the problem is, but sadly not how to solve it. On my machine the addin works perfectly fine. But when running the addin with "logmode all" on our customers pc we get the following log.
