Hello, FWIW: *any* program that has open listening ports is potentially vulnerable to attack from the internet. So BT is too.
See for example: http://torrentfreak.com/bittorrent-clients-vulnerable-to-remote-dos-attack-080117/ Google for "vulnerable bittorrent" results in 110000 hits. You better have hardware router with strong firewall and good set of pocket filtering rules, or better yet - separate computer without your trading software (and potentially passwords and other sensitive data) on it .
