I'm having some fundamental problems with "non-guarantee" spreads on financial (treasury) futures. I would like to enter a four legged intercommodity spread with four different instruments. IB only allows two legged intercommodity spread orders, although it allows you to create & view a four-legged intercommodity spread. Is there a way to receive an alert on such a four-legged spread, or better yet, enter such an order that can execute all legs simultaneously? Cyborg Trading says that their software can do that; however, the monthly leasing cost of that software is a bit expensive. Thanks, Walt
