The new standard for liquidity.

IEX is known for its deep midpoint liquidity that allows investors to trade in size without moving the price. IEX executes the majority of its volume at the midpoint – a far higher percentage than any other exchange.

The new standard for price.

Price is about more than the best bid or offer.

IEX is raising the bar for execution quality. Our technology is designed to facilitate trading at accurate, up-to-date, and stable prices, resulting in the lowest average effective spread of any U.S. exchange.
