Can't see the contents of a data file in terminal
I have downloaded a number of input files from the NASDAQ website (for example ftp://emi.nasdaq.com/ITCH/01302018.NASDAQ_ITCH50.gz) After decompressing (I double click on a Mac) I can't see the file contents using head or tail or cat. I only see gibberish characters. I have tried downloading each file three times or so. Are there any settings in the terminal that I should change (it's my first time doing this on this machine).
Also I tried checking their MD5 with what is provided on the website. It appears they don't match. What can be done in this case? Again, I downloaded them multiple times to account for the possibility of bits being dropped, etc.
I assume popular website like that will not upload corrupt data files, right?
Could you guide me through what I need to do to see the contents of the files? I have never faced this problem before; I was always able to inspect a file by doing head or cat.
The files are in this folder: ftp://emi.nasdaq.com/ITCH/
