Charts via DSWS or any other API?

Dear all,

I have received the following question from a customer:

"We have used a url to retrieve this type of graphs like the following example: https://refini.tv/3NyvoSK

This sample url is retrieved from Refinitv Eikon, where we use this in the AS IS situation for a few hundred fixed isin codes.

But we need to make this graph retrievable for a few thousand isin codes in the new solution, where we expect frequent changes to the scope of isin codes.

Could you help us figure out how to retrieve this graph based on isin code in DSWS?

Or which DSWS request is best suitable for this data?"


Is there any way to allow for this?


Thanks and regards

Silke

Datastream Web Service supports ISIN codes. You can specify a list of instruments by using a comma-separated string. 'X' is a default field for instruments. You can use the Datastream Navigator to search for instruments and data types.

The code looks like this:

df = ds.get_data(tickers='DE000ZAL1111,DJES50I',fields=['X'], start='2017-01-01', end='TODAY', freq='D')

The output is:

Then, you can use the retrieved data to plot a chart.

However, Datastream Web Service has limitations, such as the number of instruments in a request message. For more information, please refer to the DSWS user stats and limits document.
