Abstract

I examine the impact of cross-venue latency on market quality using a model of informed trader competition in a fragmented market. As cross-venue latency decreases, liquidity and price discovery improve while the expected profits of informed traders decline. Moreover, a fall in the latency of one venue can harm liquidity at the other venue. An extension predicts that, as the informed traders consolidate or outsource trading, benefits of shorter cross-venue latency are attenuated and its harmful effects intensify. My model generates testable predictions about the effects of changes in cross-venue latency on market quality.

Keywords: latency, market fragmentation, liquidity, price discovery
