Order Behaviors

• Market orders are matched within AMEX's ANTI matching engine if AMEX is currently the best bid/ask of the market (that is, "at the inside"). If not, the order is routed using the Intermarket Options Linkage. Any residual volume will not be routed to the next price level until all quotes at the current best bid offer are exhausted.
• Marketable limit orders are matched within AMEX's ANTI matching engine if AMEX is currently the best bid/ask of the market (that is, "at the inside"). If not, the order is routed using the Intermarket Options Linkage. Non-marketable limit orders are posted to the AMEX book. The best bid and offer in the AMEX book will be displayed in the Market Depth window (under the AMEX market participant ID).
• Stop Market Orders are initially routed to our stop server until triggered. Once triggered, an order routed to AMEX will behave as a Market order.
• Stop Limit Orders are initially routed to our stop server until triggered. Once triggered, an order routed to AMEX will behave as a Limit order.
