Hey community, I am very new to this topic so my question might be quite simple:
I am currently researching historical stock market data(Jan 1st, 2018- Oct. 12th, 2020) of different European indices using the Excel DataStream Plugin. This worked without any Error for all indices, but I get back an Error for the Italian FTSEMIB (Invalid Code or expression entered)- even though I didn't change any of my input (besides Index Name.)
How can i fix this error?
