Trading firms, from Wall Street banks to high-frequency hedge funds and market makers, spend millions each year to place their trading models right on exchange servers. It’s a big revenue generator for both traders and the exchanges, but is it right?

While there are several other issues at play on Thursday, where politicians are hoping to get a grasp on how to prevent another Knight Capital KCG -4.76% snafu or another “Flash Crash,” collocation is as good as any place to start.
Most investors rely on feeds that consolidate prices throughout the market. Through computer hook-ups that connect exchanges in New York, Chicago and other cities, an average trader will see one consolidated tape of prices.
