Order Quantity Modification

In response to user demand, we are introducing another feature that will make it easier to keep track of your net open orders: You will now be able to modify a total order quantity. This means that you will be able to specify the new total order quantity when you modify an order - even if that order was already partially executed, without having to wait for an updated timestamp from the Eurex host.

For example, if you have an order for 100 lots in the central order book and you are filled on 30, you could decrease the total order quantity to 50 lots without needing to subtract your filled quantity. In this case, you would still be working 20 contracts in the order book.
