How to download all files from an FTP directory?

I am not experienced in unix or downloading files from FTP, html etc. so haven’t been sure if I can safely use some other examples/questions given here.

I am looking to download files from an ftp directory into my server, with getting all the files in an ftp directory (but not downloading any other parent directory files, just the ones at this ftp: ftp://ftp.ebi.ac.uk/pub/databases/opentargets/genetics/190505/sa/molecular_trait/)

From what I found I think this will work but I’m not sure:

wget -r -np -nd ftp://ftp.ebi.ac.uk/pub/databases/opentargets/genetics/190505/sa/molecular_trait/

Am I along the right lines or should I be using other – arguments? I have also seen lftp can be used but I am unsure how to use that either.
