Internet data providers ??

["Finn Larson" <larson@xxxxxx>]

Does anyone actually trading with internet tick data feed ?
What providers do you use? Signal Online, PC Quote, something else ?

I compared tick data for SPH9 from:
Omega ftp site (tick data/signal), 
CME ftp site (voltick),
Signal Online that I'm collecting now 

I can say that Signal Online delivers ticks much closer to 
original (CME voltick logs) than files on Omega site. Why?

REgards,
