In this op-ed, the author claims that “the ‘market makers’ … are being driven out”. However, if you visited the floor of the NYSE during the last several years, you know that all market makers i.e. specialist firms, are making markets using algorithms. This enables them to post more efficient quotes and provide liquidity faster. As HFT-High Frequency Trading activity increases these specialist firms make their market making algorithms faster, otherwise they will not be able to compete. This fact is no different in any other business. If airlines don’t upgrade their planes or if ISPs don’t upgrade their communication networks to faster speeds, they will not be competitive in their industries and will be “driven out”.
