Just got this from my broker. Don't know if it has been mentions before https://dl.dropboxusercontent.com/u/10264767/New Folder/CME_Fee_Increase.pdf
So my ES trades would be $0.02 more per round turn; ZB increase is more dramatic. $0.30 r/t. But now the r/t price is $2.24 on ZB. Certainly won't kill my occasional ZB punting. Those are my major products affected. FX doesn't seem to be affected. Yes, all increase is bad. Agreed. But anyone doing heavy enough volume to get affected badly can probably negotiate with the broker to get some commission reduction.
