Dowloading Tick Data, Converting to .HST and Placing in History Folder?

 

Hi there guys.


I am using a tick downloader called QuantDataManager, it downloads tick data from dukascopy going far back in time.


This downloader has an "export to MT4" feature (which exports in .FXT or .HST files). 


I never did this before so please correct me if I am wrong. What I need to do is just copy and paste the .HST files into the history folder, then when I launch MT4 and scroll the intraday charts back in time (let´s say 5m timeframe), they are gonna go as far as 2003, for example? (I am downloading EURUSD tick data that starts in 2003).


What is gonna happen with the incoming tick data from the broker, it is gonna be merged into this new .HST file?
