Exchange Order Book

The Exchange does not maintain an order book.

Order Feed Behavior

ICE Gateways Version 7.3.1 and higher use a FIX Order Server to process order and fill information with the exchange. This connection uses a bi-directional stream of ordered messages between the ICE FIX host and the TT Gateway.

Order Server Data Flow

The following is a description of order data flow from the Order Server to the Exchange host:

• The Order Server connects to ICE Gateway using connection information contained in the hostinfo.cfg file.
• The Order Server downloads all order data from ASX.
• X_TRADER® logs into the TT Gateway.
• X_TRADER® submits an order to the Order Server.
• The Order Server sends an ACCEPT/Add message to the trader’s Audit Trail in X_TRADER®.
• The Order Server sends the order to the ICE Gateway host.
• Upon receipt, the ICE Gateway host sends an order confirmation back to the Order Server.
• The Order Server sends the order confirmation (as an OK/ADD) to the trader’s Audit Trail in X_TRADER®.

Fill Server Data Flow

The following is a description of fill data flow from the Fill Server to the Exchange host:

• The ICE Gateway host matches the order.
• The ICE Gateway host sends a fill to the Order Server.
• The Order Server records the fill in the fills.tbl file.
• Simultaneously, the Order Server:
  • Sends a fill response to X_TRADER®. X_TRADER® displays a fill in the Audit Trail. X_TRADER® updates the relevant files and screens (e.g., if it is a complete fill, the order is removed from the X_TRADER® Order Book).
  • Sends the fill to the Fill Server.
• The Fill Server updates the .bof file and sends a fill to X_TRADER®.
• X_TRADER® displays the fill in the Fill Window.
