About 3 months ago I became a CME member under Rule 106.R Electronic Corporate Member - Volume Incentive Program. This entitles me to Rule 106.R Electronic Corporate Member - Holding Member rates during ETH. IB refused to pass the holding member rate discount onto me stating they were unable to differentiate between the two and would just charge me the higher rates. I only use them as a secondary clearing firm so I didnât make a huge deal about it. After becoming a member on the NYMEX today I got an E-Mail stating I will receive a rate of $0.70 per contract not the $0.45 that you receive for day trades. While IB has not gotten back to me yet about the NYMEX issue I suspect they will tell me the same thing as they told me prior. I figured this was against exchange policy so I gave CME a call and they told me that this was not aloud and IB should be making an adjustment every month for the difference. The woman I spoke to will be escalating this issue to her boss and I suspect IB will have to change their policy and not steal from their customers because just charging the correct rates is a little inconvenient for them. Anyone who has any memberships on the CME, CBOT, or NYMEX I encourage you to check the CME fee schedule to make sure that you are not being overcharged and if so report IB (or whatever firm you clear with) to the CME. And any IB staff who monitor these forums, I encourage you to try to defend your companyâs actions.
