I think this is an alarming trend where "no lose", "magic bullet" systems are found to be tied to only one or two brokers. I walk away as soon as I see this. I use only Alpari-UK for BO's and fail to see why any respectable product would not include established main stream brokers like Alpari in their list (instead of one's we've never heard of)

MT4 has no registry entries so is ideal for transferring to a USB drive if portability required. My son dfoes this all the time (come to think of it I think he uses "VMware"). In Win7 I have MT4 in a sub-directory of my desktop to overcome interference from Windows.

I just use Notepad text editor. The trick is to save-as "hosts" then shift+enter keys. Easy peasy.
