1. The initial margin check is done at the time of order submission, and order modifications. And also on order updates from the exchange. It is extremely fast and happens within microseconds.

The Teton order routing service maintains an account balance and open P/L for each account. Margin is compared to this (Net liquidating value). These balances are updated at the end of the day with the clearing firm values.

2. Yes they do know the positions in real time. This information is accessible to both the clearing firm and broker.

3. There is no auto liquidation in this case. This would be a manual action done by the clearing firm.

4. Those types of events have no relevancy at all on order processing. Orders like OCO orders work in a standardized way based on fill and cancel events, of the parent order or sibling order. And the filling/execution of those orders is done by the exchange.

5. No, the CME does not maintain positions. Clearing firms do, and there is a mechanism by which any position differences, are alerted to the clearing firm and appropriate action can be taken by them.

6. Yes this does exist. The limits are high enough, to allow order entry, but prevent any kind of abuse or accidental sending of too many order messages in a short amount of time.
