Level II quotes in ThinkOrSwim

  1. I am trading newbie, and I was wondering why Level II quotes in TOS only display ECNs in their level two screen (like ARCA, BATS), and there are no quotes from actual market makers like GSCO (Goldman Sachs) or MSCO (Morgan Stanely). Does any trading platform show quotes from the market makers too rather than only ECN's??
