Ok, I'm looking for help entering an option spread order in IB's TWS. I want to sell a call credit spread. I've read the user's manual on how to do this. IB offers 4 ways to input the debit or credit amount which doesn't make sense. They're talking about buying or selling for a credit as 2 ways, or buying or selling for a debit for the other 2 ways. For as long as I've been invloved with options trading (13 years), I only know that you can either buy a spread for a debit and sell a spread for a credit. I don't understand how you can buy a spread for a credit or sell a spread for a debit. But this is how the manual explains it. If you want to sell the spread for a credit, you would enter the credit amount with a positive number. If you want to enter the credit spread with a buy order, you enter the credit amount with a negative order. Does this make any sense? Anyone doing combo vertical spreads with IB? How are you entering the orders? Maybe I'm just not understanding something here, so I may just do 2 separate orders for each leg so I don't screw up the combo order. Any help is appreciated.
