Anyone have any luck with interactive brokers sponsoring a CME seat lease? I trade around 20k contracts a month, mostly ES, NQ and the treasury futures and haven't had much luck with them offering to sponsor me unless I have a very large account equity, many times over the value of the seat. I also trade some equity ETFS, FX (both futures and spot) which makes it tough to find a broker that supports it all. Looking forward to hearing about anyone's experience with IBKR and am all ears for any other ideas as well.
