It seems no one is looking at the bright side of this.
For traders who keep changing their orders again and again with small # of executions, they will be penalized.
And that is the norm for pit trading, those who keep adjusting their orders every few minutes will tend to get their orders ignored and sometimes, the firms will simply ask the customer to take their business elsewhere.
So, that is not much a problem - the small traders just have to deal with it, like any other issues in trading.
Now, take a look at the bigger players who hide themselves behind customized bots that place 500 small orders to fulfill the objective of, in reality, 1 single order.
It is going to cost these players and they will have to rethink their strategies of hidng orders through their bots.
That way, you will see "real size" of the trades.
Based on what we've seen in past 6 months of tick data, it is obvious a lot of the bigger size trades no longer show up in the eminis like ES, NQ, etc. when real-time extremes are hit. If these trades started to show up again, CME's new rule will actually help every one trading these instruments ... except those being exposed
