I attempted to execute a buy-write using futures (ES) and futures options on IB/Globex. I received a notice stating that the buy-write was not recognized. Is there a way, using the generic combo feature, to create this buy-write? I tried using the generic as well as the single tab. I think I discovered the problem, but I am not sure. When I entered the underlying and the exchange, "buy-write" did not come up as a user-defined trade--perhaps it is the nature of IB or GLOBEX. If this is true, then the only way to enter a buy-write is using the basket trader feature OR legging in. The problem with either is getting a decent execution for the short option, since the spreads are wide. Anyone have any suggestions?
