Understanding Order Management
Order Server Data Flow
The logical architecture diagram illustrates the following order flow:
- The Order Server connects to TT LME 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 TT LME Gateway host.
- Upon receipt, the TT LME 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 Logical Architecture diagram illustrates the following fill flow:
- The TT LME Gateway host matches the order.
- The TT LME 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 (i.e., 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.tbl file and sends a fill to X_TRADER®.
- X_TRADER® displays the fill in the Fill Window.
