Securities trading and markets are in a state of permanent transformation. Trading in all asset classes has grown exponentially in volume in the first decade of the 21st century, fuelled by algorithmic trading and high-speed execution. The characteristics of these markets make them increasingly hard to monitor. Changing the process of storage and retrieval could allow regulators to see everything where it sits, getting a picture of the real market in real time. This is the first of two papers brought to you by BIPB, in conjunction with Datawatch that looks at how using 21st century tools, regulators and market operators can better police markets.
