Futures Spread Orders

I know I ask this question a few month ago but actually i can not remember the solution you gave me.



I trade futures spreads , and i am looking to place spread orders in collective2, but I do not know how to make it. Of course form me and my strategy’s is not possible to legging in.

I need to place limited spread orders in the futures market like Sell Lean Hog Jun July at $0,525 !!!



Or Buy Silver May December 2011 at -$0,075



Thanks a lot and sorry for asking the same question like 3 month ago.
