IB: conditional orders based on "cushion"

Hello,

How does it work? Can you create for example an order that will remain valid until the order is % away from the instrument?

When we use "price" as the condition, can the underlying be the instrument you placed the order on? I wanted to do it with futures calendar spreads but I don't know how to enter the "underlying"?

Thanks a lot.

 

Someone from IB? It's from the last TWS release.

 

I made an error. The cushion condition is a margin condition.

However, how does it come we cannot use calendar spreads to define PRICE condition.

That would be great, IB.
