Under the Function button in Datastream a lot of useful options are hidden. One of them is the option to rebase an index: you can choose the date this index is rebased to 100.
These are the steps you have to take:
- Open Time Series Request in Datastream
- Enter the code of the index or use Find Series to find the code
- Click behind Datatypes/Expressions the Fx-button
- Search for Rebase
- Use for example REB#(expression,date) and click OK
- Enter the date behind Date (in this format: dd/mm/yyyy)
- Click OK – the function is entered behind Datatypes/Expressions
- Enter your start- and enddate
- Click Submit – the data download starts
