Tower Research Capital

The New York high-frequency trading firm that Mark Gorton and Alistair Brown founded in February 1998 and built into a multi-asset automated trader connected to more than 150 venues — the training ground, reportedly, of Hudson River Trading's founders, and the firm whose enforcement record shows the compliance bill for misconduct inside a speed business. Its affiliate Latour Trading paid a record $16m for net capital violations (SEC, Sep 2014) at a time when it sometimes accounted for ~9% of US equity volume (reported); three of its traders spoofed CME equity-index futures from 2012, and Tower paid ~$67.5m ($67,493,849) to the CFTC and DOJ under a deferred prosecution agreement (7 Nov 2019) — the largest spoofing relief to that date — plus $15m to a class of futures traders (approved 2021). Gorton's other life — the file-sharing company LimeWire, shut by a court in Oct 2010 and settled with the record labels for $105m in May 2011 — is part of the story too: a founder-owned firm carries its founder's risks.
