Use of Datastream Expressions

MyScreenName

Hi !

I hope this finds you well.

I'm trying to extract the performance of the EUR (for 3m and YoY) as well as the French 10Y yield.

I was advised to use Datastream Expressions:-

" Please consider using the Datastream Expressions that I presented (ex: PCH#(X,-3m) where X is the underlying series placed in the Series field). "

However, I've never used Datastream Expressions before.

How should i structure my query ?

ds.get_data(tickers='<EUR=>',PCH#(X,-0d))
ds.get_data(tickers='<EUR=>',PCH#(X,-3m))
ds.get_data(tickers='<EUR=>',PCH#(X,-1y))


ds.get_data(tickers='<FR10YT=RR>',PCH#(X,-0d))
ds.get_data(tickers='<FR10YT=RR>',PCH#(X,-3m))
ds.get_data(tickers='<FR10YT=RR>,PCH#(X,-1y))

Thanks for your help !

Bests,

Victor

Thank you for reaching out to us.

You can try this one.

ds.get_data(
    tickers='<EUR=>',
    fields=['PCH#(X,-3M)'], 
    kind=1)

Or.

ds.get_data(
    tickers='<EUR=>,<FR10YT=RR>',
    fields=['PCH#(X,-3M)','PCH#(X,-1Y)'], 
    kind=1)

Please contact the Datastream support team directly via LSEG Support and ask for fields, expressions, or instruments that can provide the required data.
