Rest. Easy.
IEX is designed to provide execution quality by protecting resting orders.
Pending SEC approval, IEX plans to become a primary listing exchange and support its first IEX-listed company in October 2017.
Order types
We keep it simple. IEX offers five order types, some of which have innovative predictive capabilities that are designed to protect resting orders from trading during unstable, potentially adverse conditions.
The IEX Signal
The IEX Signal is designed to identify when the quote is unstable and helps IEX protect resting orders.
Trading hours
Orders may be executed on IEX or routed away from IEX during the Pre-Market, Regular Market, and Post-Market Sessions, collectively known as "System Hours".
