UDS Supported Order
Types
4 Configuring Market Data
• If accepted, the exchange multicasts the security definitions for the
created Combo or Covered strategy to the Price Server.
• The Price Server creates the Combo or Covered UDS contract and makes
it available for trading and quoting.
The following order types are supported for Covered and Combo UDS
instruments:
• Limit
• Market-Limit
The CME Group supports the following order qualifiers for a Combo UDS:
• GTD
• GTC
• FAK
Client Application Impact In addition to the risk limits you can establish in Guardian, P&L calculations and
risk management for trading UDS contracts are supported by the following
minimum versions of these TT clients:
• X_TRADER ® 7.6
• X_RISK ® 7.3.2
• X_STUDY 7.2
• FMDS
• TT USER SETUP 7.0.3
Covered User-Defined Strategies can be created and made available for trading if
you decide to do so. Setting the ProcessCoveredUDS parameter to ALL in the
hostinfo.cfg file will download all Covered UDS security definitions, including
Covered User-Defined Strategies with multiple Futures legs. However, the client
trading applications in your trading environment will not correctly calculate risk
for the multiple Futures legs of the Covered UDS. Refer to the following example.
Example: A Covered UDS defined with multiple futures legs
Created as...
+1x6E Nov09 C11100:-.5x6E Dec09:+.5x6E Nov09
Will be incorrectly risk checked as...
+1x6E Nov09 C11100:-.5x6E Dec09:+50x6E Nov 09
This example illustrates that risk calculations for one of the Futures legs will be
incorrectly multiplied by a factor of 100, causing traders to surpass their risk
limits.
