Quote from cdcaveman:
So what your were talking about as far as "implied" ted spread.. is i would construct the combo, and when i went to put the spread on the margin relief would just show???
An implied spread is one where your software constructs the spread for you and executes it as a spread. Your broker will margin it effectively as an inter-market spread. It should be on their website or ask them to be sure. Granted, futures brokers are different then places like IB and TDA. I seem to recall the overnight margin being something around $750 per spread. It may even be less now with vol so low.
