Hi Def,

Any news yet?

Thanks.

feedback rec'd was that it is not a high priority. I think you'll see better margining on iron condors and the like first.

I was told about a month ago that "immediate exercises" will be available at IB within the next couple months.

Hi Guys 'n' Gals,

Does anybody know if 'immediate exercise' is now available through Interactive Brokers? i.e. If I am already short 1000 shares of WMT and exercised 10 WMT calls - would both transactions offset each other IMMEDIATELY, so that I am deemed to be flat as far as WMT is concerned (assuming ofcourse I have no other positions in WMT)?
