TT CME Gateway System Administration Manual - Trading ...

A Configuration Parameters
• [order_session_1]
• [order_session_2]
The first section in hostinfo.cfg does not include the _# identifier.
Whenever a trader submits an order, that trader’s Member ID determines which
order session carries the order. The Member ID maps to the order session’s
member parameter.
The table below includes the parameters that you use with the [order_session_#]
section. Default values are included when applicable.
Warning: You must cancel all working orders before altering or removing any iLink
session information. Failure to do so can result in orders becoming lost or deleted
from the CME Gateway.
Parameter Description
[order_session_#] This is the section title, where # uniquely identifies the order
session.
Member=SessionIDFirmID Also called the Member ID. This is a concatenation of the
customer’s FirmID and SessionID, both of which CME Group
assigns to the customer. This parameter has only six alphanumeric
characters.
Each [order_session_#] section must have a unique Member
parameter.
Warning: If there is a duplicate Member parameter
configured on a multi-session CME Gateway, the
Order Server will not start.
Password CME Group assigns this value to the customer and refers to
it as the Password.
ILinkPrimaryIP The exchange refers to this value as the IP address. The
exchange provides the IP address, which is an IP address for
a CME Group FIX Server through which the customer can
connect to the exchange. The customer must use one of
these addresses for the PrimaryIP.
ILinkPrimaryPort The exchange refers to this value as the port. This is the port
on the CME Group FIX Server which the TT Gateway
connects. If the exchange provides two port numbers, CME
Group assigns each port to a specific IP address. If this is the
case, the customer must use the appropriate number for
each of the port parameters.
