Speed is a double‑edge sword – the faster you can quote and fill, the tighter the spreads and the higher the apparent liquidity, but you also create a perfect storm for flash crashes. The tech side is all about sub‑millisecond latency, co‑location, and sophisticated statistical arbitrage that can unwind millions of shares in seconds. On paper, the speed advantage does cushion order flow, but in practice the same infrastructure that pushes liquidity can amplify noise and trigger runaway algorithms that see the market as a zero‑sum game. So, it’s not just a matter of “does speed beat risk?” – it’s how you design the risk controls, the fail‑safe mechanisms, and the regulatory framework. The balance shifts each time a new latency hack or an AI‑driven model is deployed. In short, the tech can boost liquidity, but if the safety nets lag, the risk of a flash crash spikes.
