I just updated the Interactive Brokers api to support Ib’s 9.65 new features(ShortSale Exemption functionality).
I also finally added parameterless constructors to all of the event args so that they can be serialized/deserialized.
Added the warrant type to securitytype.
Fixed orderId going to 2^31-1 when it should be interpreted as zero.
Check it out in subversion, or I will make another release soon.
