Quote from Barbaris:
I am a daytrader. There are 5 min and 1 day. I like trading pennystock and several stocks from NYSE. The tape helps me to determine big players and feel a trend. If I do not see real deals I cannot indentify strategies of these players.
I am not sure what you think you are seeing with IB, but for daytrading stocks they are perfectly fine. If you look at the time and sales, you will see almost every trade. If you trade with them for a while and check your fills against the time and sales you will see that the info is almost spot on. Of course you should use a different charting service along with time and sales, because IB's charts and time and sales presentation is cumbersome at best, but the feed is fine.
You can easily use IB market feed fed into a solid charting program or DOM to trade for a couple cents per trade all day long, although the commissions would eat you alive.
