I currently have a list of hundreds of Latinamerican bond ISINs on a CSV file. I have a script with both the Python Eikon API and Pydatastream that obtains a list out of the CSV and does analysis on the bonds. However, I run into issues every week because the list is static and a some number of the bonds get called every week and the query fails. So I have to manually go into the CSV file to check which bonds were called. I would like to be able to dynamically get a list (maybe searched-base) of Latam bonds and be able to return their ISINS, instead of having to manually update a CSV file. Any idea on how to do this?
