Updating imported brokers price feed

Hi, I want to store my broker’s price feed to QDM. The only option that I found is using import button, the problem is if I do import file then the data earliest data would be erase since my broker only store price feed for a certain year. Is there an option to update the data rather than write off everything with the new data?

Hola,

if you supply fresh data the older data should persist. It would append new data and create continuous stream

So I just need to import the latest price feed and import it to QDM the program will append the database itself and not overwrite it, is this correct?
