I want to lower the day trading margins in my account for the e-mini s&p 500, but I also periodically keep overnight positions. Does that affect my day trading margins?
No. Your lower day trading margins would be respected by our FCMs. But, you would have to lower your positions before the Globex day session ends. All overnight positions for the ES contract have to follow the CME overnight initial margin requirement.

The CME changes their margin requirements. Can you provide a link for that as well? By the way, thank you for the fast reply.
