Maybe there's a bug in the paper trader? I really don't know how you're getting what you're getting. Nope, that's not it--paper trade shows me the correct bid/ask spread for the combo too. Here's what I show right now
I got a question, do you trade the corn beans spread? Does a generic spread like this mean u have to pay 0.25 spread on each leg of the spread on all orders? Even if you use limit, do they still have a 0.50 spread and send the order when your limit price goes offer on the spread? For the calendar spread, do IB send it to the exchange directly where the spread trades as one product?
You cannot combine ECBOT futures contracts into a combo, unfortunately--TWS rejects it. So, you have to trade each leg individually.
Why? So, u mean the quote on the Jul/Dec spread that you see right now -14 cant be traded ? Instead, you have to enter 2 orders sepreately as 2 outright trades?
