CT is a LII platform. There are nearly as many of these now as there are d-brokers. INvest in, EdgeTrader, CyberTrader all route orders directly to nasdaq though it does give the user the ability to choose ECNs, Island, SOES etc... First few weeks you start going nuts as you see the dollars lost and gained realtime, on 1000 shares and you can get pretty freaked out. A must have for any trader to complement a d-broker but not to replace one. One common problem with LIIs is holding overnight. Penson or who ever is holding the funds shows an opposite trade on any thing closed out the next day. In other words, selling long a stock held overnight shows up as a short, and prevents you from trading in that stock until settled T+3 etcc,,, |
