IB order type / some trick for this?

[Abhijit Dey <omegalist@xxxxxxxxxx>]

I have a ER2 / EMD spread on for a few days. I want to unwind this when 
say EMD - ER2 is 10.00. Without having to write code, is there some kind 
of conditional order I can put in to do this for me? Using IB.

Any innovative order entry ideas most appreciated. Then I can just put 
in a GTC bracket and forget about this. Thanks,

Abhijit
