Enhancements Support for Hedged Volatility Orders The following attributes have been added to the Order socket client properties in the Java and C++ APIs and to the COM object in the ActiveX API to support hedged volatility orders: deltaNeutralOpenClose - This string attribute specifies whether the order is an Open or a Close order and is used when the hedge involves a CFD and and the order is clearing away. deltaNeutralShortSale - This boolean attribute is used when the hedge involves a stock and indicates whether or not it is sold short. deltaNeutralShortSaleSlot - This integer attribute has a value of 1 (the clearing broker holds shares) or 2 (delivered from a third party). If you use 2, then you must specify a deltaNeutralDesignatedLocation. deltaNeutralDesignatedLocation - This string attribute is used only when deltaNeutralShortSaleSlot = 2.
