I'm trying to learn how to use the One-Cancels-All (OCA) feature for options orders in IB. Thanks to @gf58 I know that it's possible to do it in the OptionTrader window. Let's assume that I want to place only one order for a DIS calendar put. I'd be fine with strikes 105, 110 or 115. Using the Strategy Builder tab I can create a calendar order and then move it to the Quote Panel (I did it with 110 and 115 strikes). But the place to create an OCA order is in the Orders tab where I inserted the OCA Group column. Unfortunately, I only have a single leg per order here. How can I get a calendar put in the Orders tab?
