I think you dont know what you speaking about...
FESX is a future, and there is only one price, the price on the exchange. Its a regulated instrument, NOT like FOREX.
with someone like IB that will be more like 1.26 in total for a roundtrip, so a CFD is like over 50% more expensive and that is if you don't sit on the bid and ask then you pay no spread at all, just 0.26 for costs. Like I said you really need to wake up !
