IEX (Exchange)

Investors' Exchange (IEX) allows the trading of listed NYSE, AMEX, NYSE Arca, Nasdaq, and IEX stocks. Even, odd, and mixed lot orders are supported (even lots are multiples of 100, mixed lots are not, odd lots are orders less than 100 shares).

• Orders can be placed from 8:00 A.M. to 5:00 P.M. Eastern Time.
• IEX accepts market orders from 9:30 A.M. to 4:00 P.M. and limit orders from 8:00 A.M. to 5:00 P.M.
• IEX accepts decimal increments precise to two digits (that is, prices as fine as .01).

In the event of a connection outage between the TradeStation Order Execution Network and IEX, all open orders will be canceled by IEX.

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.
