A machine-to-machine program trading platform that uses computers to transact a large number of orders at fast speeds. High-frequency trading uses complex algorithms to analyze multiple markets and execute orders based on market conditions. Typically, the traders with the best models, lowest transaction costs, and fastest execution speeds are most successful. It is estimated that the majority of all securities and commodities exchange volume comes from high-frequency trading orders. A high-frequency trading process typically takes place in milliseconds or less and results in greater liquidity, cost savings efficiency for the buyer, and often higher eCPMs and/or better monetization for the seller.
