Quote from stockerup:
I do not think it is unreasonable to ask IB to offer a level II feed that includes integrated ecn's. As previously mentioned by AAA , level II is worthless if you can't see the ecn's along with the mm's.
I recently subscribed to IB's level II and it is priced at $20 per month. I found it to be very unstable, and of course, it didn't show the ecn's. I ended up shutting it down after about an hour, but still got charged for the whole month-- even though, I called and complained. I, also, sent an e-mail to IB and asked why they didn't include ecn's in the level II, and the reply I got was that I could get that info by selecting the individual ecn's on TWS. That was so ridiculous that I didn't bother to reply.
Anyway, my feelings are that a broker that is really concerned about their bottom line should be concerned about providing the best tools possible for their traders. It is simply synergistic.
