Linux Friendly Online Brokerages?
freelunch asks: "I need to switch online brokers and, not wanting a dedicated Windows box just to trade, would like to find one that has Linux friendly Level 2 tools. Many of the Java trading platforms are unreliable/incompatible/unsupported under Linux (Scottrader is very unreliable and not L2). Any help?"
For those non-professional traders, what is 'Level 2'?
