Initial Configuration<br />
<strong>CME</strong> <strong>Gateway</strong> <strong>System</strong> <strong>Administration</strong> <strong>Manual</strong> 47<br />
<strong>Trading</strong> Technologies International, Inc.<br />
Configuring Global Settings<br />
Time and Time Zone Due to the default settings in its configuration files, <strong>TT</strong> recommends that you set<br />
the <strong>TT</strong> <strong>Gateway</strong> to run in the CST time zone (Chicago time) with Daylight Savings<br />
enabled.<br />
If you decide to run the <strong>CME</strong> <strong>Gateway</strong> in another time zone, you must:<br />
• Run the <strong>CME</strong> <strong>Gateway</strong> in the correct time zone and daylight savings setting<br />
associated with that time zone.<br />
• Adjust the times in ttchron.ini to match the time in which the <strong>CME</strong><br />
<strong>Gateway</strong> runs.<br />
• Adjust times in Fill Server section of the aconfig_local.xml file.<br />
Aconfig Time Zone<br />
Parameters<br />
You must pay close attention when configuring the time zone settings located in<br />
the Aconfig.Core.Server.Exchange-Specific.Exchange-flavor.Time.Zone<br />
directory. These settings directly impact price and fill server operation.<br />
When resetting these parameters, you must restart both the Price and Fill<br />
Servers.<br />
Account Names The <strong>CME</strong> Group restricts account names to a maximum length of 12 characters.<br />
For longer account names, the exchange truncates any additional characters<br />
beyond the 12 character limit. This results in orders being rejected by the<br />
exchange.<br />
Member, Group, and<br />
Trader ID Format<br />
Example:<br />
<strong>Trading</strong> Firm ABC based in Indianapolis decides to run the <strong>CME</strong> <strong>Gateway</strong> in the Indiana<br />
time zone. ABC sets the system clock to Indiana time, which is CST, and turns off<br />
daylight savings. Whenever Daylight Savings changes, ABC edits ttchron.ini to account<br />
for new time schedules.<br />
Warning: You must restart the Price and Fill Servers after changing<br />
the time settings in the aconfig_local.xml file.<br />
Warning: Failure to restart the Price and Fill Servers after changing the Aconfig time<br />
zone setting can result in missing fills.<br />
Warning: Users must use account numbers that do not exceed 12 characters in<br />
length. If your account name exceeds the 12 character limit, <strong>CME</strong> Group will prevent<br />
you from sending orders to the exchange.<br />
<strong>TT</strong> Trader IDs on <strong>CME</strong> <strong>Gateway</strong>s use the format SessionIdFirmIdxxxyyy, where:<br />
• The <strong>CME</strong> Group determines the values of SessionId and FirmId. Trader’s<br />
use this concatenation as their Member ID when logging into X_TRADER®.<br />
• To better manage trader groups, if the customer wants to use a custom<br />
FirmID, they may do so. However, the customer must communicate this to
