This interview podcast features Aaron Fifield interviewing Dennis Dick, a seasoned equities trader and market structure analyst. The conversation begins with Dick's early trading experiences with penny stocks and his transition to a prop firm, Bright Trading, in the late 1990s. The discussion then delves into the evolution of trading strategies, the impact of high-frequency trading (HFT), and Dick's current approach, which focuses on taking liquidity at the market open and close, leveraging order flow information to identify price inefficiencies. Dick emphasizes the importance of adapting to the changing market landscape, avoiding passive limit orders, and utilizing available market data to gain an edge. He suggests that while some HFT is beneficial for market efficiency, predatory strategies exist and should be avoided.
