Order Behaviors

  • Market orders are matched within IEX if IEX is currently the best bid/ask of the market (that is, "at the inside").
  • An Immediate or Cancel (IOC) order is matched by IEX at price at or better than the best bid/ask of the market (that is, "at the inside"). Non-marketable orders are immediately rejected, partial fills will be accepted.
  • Marketable limit orders are matched by IEX at price at or better than the best bid/ask of the market (that is, "at the inside"). Non-marketable limit orders are held by IEX and are not required to be displayed.
  • Stop Market Orders are initially routed to our stop server until triggered. Once triggered, an order routed to IEX will behave as a Market order.
  • Stop Limit Orders are initially routed to our stop server until triggered. Once triggered, an order routed to IEX will behave as a Limit order.
  • Unfilled orders and leaves set for Minute durations (such as 1, 3, or 5 minute) expire immediately after the designated number of minutes.
