High-frequency trading surges across the globe

High-frequency stock trading is spreading around the world into more and more asset classes, but progress is being slowed by poor infrastructure, heavy regulation and opposition from entrenched interests.

In some major markets in Asia, it can take seconds to execute an equities order. That's a lifetime for a trader who uses sophisticated algorithms to trade thousands of shares in a millisecond with the aim of earning a profit from market making and price imbalances.

Turf battles between exchanges also sometimes prevent the kind of interconnected market approach that provides fertile ground for high-frequency trading. Traditional brokers and institutions, whose positions are threatened by upstart trading houses, also help to erect barriers.
