The CME exchange required SPAN margin is not $9500 and the same for 1 ES contract, which is under $5000. This is your broker adding their own risk component. For accounts of $25,000 or more, we introduce futures accounts to Wedbush Futures that uses SPAN margin. To monitor risk, each symbol requires approval for a max order size and max position size. I have had no problem getting reasonable limits and with some platforms, getting lower margin for day traders.
Why don't you email me your contact information and I'll give you a call later.
