Three years http://spankwire.in.net/ spankwire.com Eric Hunsader, founder of the market analysis firm Nanex, says that's because he saw simultaneous reactions to the Fed's announcement last week in trading in New York and Chicago.

In theory, the trading reaction should have begun in New York several milliseconds before it began in Chicago, because information takes several more milliseconds to travel the longer distance.
