Which brokerages offer the best streaming quotes (tick level) for the best price?
I have ScottradeElite on my desktop. I have played around with it but no longer use it. The transactions that I make through Scottrade are more dependent on my goals for the securities than what the market is doing at the moment.  Keep in mind that there will always be others out there with better access to price changes than you. They also will have better hardware. We cannot beat them at their game.
