From 2nd of June 2008 Hidden volume will be enabled in Production The Term Hidden volume means that an Order Book Order can be placed with a total volume and a shown volume using the Round Robin Logic. The shown volume is part of the total volume. When such an order is partially traded and the shown volume reaches zero, as long as there is total volume remaining, an additional part is shown.
