Collar Strategy - Discount broker

i want to trade Collar Strategy with SPX Options & 2 lots of E-mini Future . Can you suggest me a right broker with less margin . Might hold a trade for 2 days.

CFD brokers provide good leverage but dont offer options.

Long collars are synthetic bull verticals.

 

If you are using SPX options to do collar then won;t you need 5 E mini not 2 to match the 1 SPX ? also you won't get cross margin perhaps? so why not use ES + ES options ?

 

Long shares at 95; long put at 90; short call at 100.

Long shares + 90 put = long synthetic 90 call.

Long synthetic 90C & short natural 100C = long synthetic 90/100 call spread.

Or do your thing across classes and add'l comms which is pointless.
