HFT is arbitrage. The ask in Chicago falls below the bid in New York, so you buy for $12.25 in Chicago and sell for $12.27 in New York until there is either nobody willing to sell for $12.25 in Chicago or nobody willing to pay $12.27 in New York anymore. Which happens almost immediately, so whoever is fastest gets the money. That means you want to be sitting right on both of the exchanges, but also that you want the fastest possible link between New York and Chicago. |
