Excuse me for my English....... I'd like to ask you a question about CME Market makers. Does every instruments have m.m. or not? Indexes maybe, but the others?....oil, currencies.... Eventually have some of you a link where I can find bid/ask spreads m.m. must put on books.
CME does employ market makers and they're not 'upstairs' hacking away at your orders. They're making markets to add liquidity to the marketplace. There's nothing nefarious about the business practice at all.
Look at the fills on what orders? Yes, they have market markers. Of course they do. Market makers are no different than paper fillers in the pits. They quote markets so others can trade. http://www.cmegroup.com/trading/interest-rates/files/EDOptions_ElectronicMMProgram-gm.pdf
I understand what you're saying, but this is different from a true MM. The CME has, in the past, instituted programs like the one you've linked to. These programs are for markets that they don't feel will have a sufficiently deep market. They will offer incentives(fee rebates ect) to people in exchange for their committment to make a market in these products. There are no such programs in place for deep, liquid markets like the ES or Eurodollar futures.
