Just join IB and learning how to do options. Is there a way to do a vertical spread on TWS's option trader with limit price? For instance I would like to do a Bull put vertical spread on GS...So I buy the 175 put april 11, the current price is $8.28 but I would like to place a limit price of $8.00. Then I sell the 180 put april 11, and the current price is $6.00 but I would like to place a limit price of $7.00. Can I place this order thru TWS making sure that both can get executed. If one does not hit the limit price then its a no go. Thanks
