So I was thinking, If you use a proxy browser site to access your AB account, would that in essence keep your ip masked well enough to do trading with your main on a regular browser ?
It would if you were able to run the ABer through the proxy as well, because then the account wouldn't be attached to the IP anymore.
If you did what Loco says then yes. If you are using a GreaseMonkey ABer then yes. But if you just log into neo with the proxy server, then log into your aber, it wont work like that. You would need to add the proxy to your ABer aswell. Very good place for proxys is proxy-list.org, 80% of their proxys work, and some even have page load times of like 0.500 seconds (like a half a second)
