Everybody seems to be confusing the definition of real-time quotes in the context of consumer trading. When eTrade or Scottrade says they have real-time quotes, its the same as Google Finance (which this is pulling) in that, its not delayed 20 minutes. Beyond that, expecting a 5' or less connection to an exchange feed is just absurd.

The barrier to entry is very high, which is why I think flash trading gives an unfair advantage to the wealthy. Of course, thats really the story of modern economics.....
