Yeah I can see that viewpoint, my view is related to exchange fees and commissions vs. min tick size.
I wasn't making the point that $5 is better or worse. I said trading fees could double during the move to the CME. If you want to discuss if the move to $5 is better or not, i have to say overall it is worse. I think the daily notional volume that is trading after the switch from $10 to $5 is lower than perviously. ie halving the value of the contract hasn't doubled the volume. This means the change has weakened this particular futures market. Also i noticed market depth did not double after the change, so again the market seems weaker to me. This will lead to more slippage for everyone under fast market conditions.
I emailed cmegroup to ask if they know yet, but as the other 3 Russell 1000 contracts CME introduced last month all had $5 tick values, im not hopeful. The the current fees for e-mini SIFs under CME are $1.18 after a slight increase at the start of the year. Brokers charge extra on top of this.
I havent traded 6E in about 8 years. But a quick look on IBs website (which could be out of date) it says CME currently charge $1.6 for FX futures, which seems like no change.
I dont think they changed the Multiplier on the 6E. Just the tick size/ spread size. So you continue to trade the same number of 6E contracts. So your costs dont change on that one. Having said all this CME could maintain the same contract spec for Russell 2K that ICE use and also carry over the same reduced charges that ICE currently charge. It could just be me being overly pessimistic. If cme get back to me, i will ask if they are going to match the current ICE fees.
Well I based my short term trades based off of tick size so if I want the same $ per tick I have to trade 2X the contracts with twice the cost.
It was actually a relativly smooth move to ice for the er2. I was trading fairly actively and didn't notice much change. The emd is is really thin in the book. But if you go mid market, you can usually get a fill. Displayed size and volume hasn't increased with reduce in contract size. Seems the ice was trying to kill the contract because they were pissed they lost it.
