At the 2013 CFA Institute Financial Analysts Seminar, held in Chicago on 22–25 July, Maureen O’Hara discussed a new market paradigm: Trading has become faster, and market structure has fundamentally changed.

LFTs can thrive by adopting trading strategies appropriate to the high-frequency trading world.
