Credit Controls Management
To set up CME Globex Credit Controls, follow these steps:
- Select the Legal Clearing Entity / Execution Firm to manage.
- Exchange Grouping (optional): Newly added exchanges will have a “0” exposure limit and appear in a separate tab. This means that the firm is blocked from the newly added exchanges.
Customers can request to re-group / modify exchange groupings or set up a new group.
Requested updates will be effective at the next Sunday start‐up.
- Credit Controls Management: To enable trading, the GC2 Risk Administrator must enter the Exposure Limit / Max Quantity Limits for Futures and Options for each Executing Firm ID / Exchange group.
- Manage Futures and Options exposure / quantity limits for:
- Futures on the Buy / Sell side (Long / Short)
- Options on the Buy / Sell side (Long / Short)
The Exposure Limit is applied to both Long and Short trades and positions.
Note: If both Exposure Limits and Max Quantity Limits are set, the most conservative value is used.
- Max Quantity Limits - In addition to currency based Exposure Limits, the risk administrator can enter the optional Max Quantity Limit (Buy/Sell) for Futures and Options by group.
To enter Max Quantity Limits, Uncheck the No Max Limit checkbox.
Newly created execution firms will have a “0” exposure limit. This means that the firm is blocked. To enable trading, the clearing firm admin must enter a value.
Exposure limits added to newly created firms or exchanges will take effect at 16:45 CT each weeknight or upon Sunday start-up.
Enable weekend trading: By default, weekend trading is not enabled.
This feature is available for authorized clearing firm risk administrators to allow (checked) or restrict (unchecked) weekend trading at the execution firm(s)/exchange group level.
When unchecked, limit values (Exposure and Max Quantity Limit) will be set to zero (0) for the weekend. Before the next weekday trading session begins, limit values will automatically revert to the previous weekday value.
To be effective for the weekend trading session, updates must be submitted before 4:00 p.m. CT Friday.
- Current Positions: Open and filled positions are calculated for a product complex per Executing Firm ID / Exchange group.
To update the Current Positions area, select Refresh .
- Total Futures Long (Fut - Long) = Sum of all weighted quantity open long futures orders + Sum of all weighted long fills - Sum of all weighted short fills.
