9/13/18... today is the first day, if you think of rollover as a period of time, not necessarily a specific day.
Today is the first day, more information on the CME website. Just keep an eye on the volume traded on the september and december contract. Once the december contract has more volume switch to the december contract.
Update. -$600 ignore the first 4 trades, Im using a new platform to take my trades for free sim trading access. So i was getting use to it. I broke my rules of after 2 losing trades, stop trading. And I paid for it. Lol
Thanks Trump ... the only thing is i needed a pop to the upside. Down 375$ today and calling it a day.
