If you're trading mostly Globex products, and you do at least 25 sides per day, then you might want to look at a CME Electronic Corporate Membership (rule 106.R). The application fee is $2,000 and you have to apply as a corporation (which means you'll have to create one if you don't already have one), but you're clearing fees for the mini equity indices and FX contracts is $1.18 RT as opposed to $2.28 RT.
If you lease an exchange membership you can get even more aggressive discounts on the exchange fees, however it costs a lot more on a monthly basis, and your trading gains will get counted as earned income in the eyes of the IRS so you'll have to pay employment taxes on it. An ECM is not considered a full membership, and thus, you are not responsible for paying employment taxes on any of your gains.
