When does the Intraday margin for futures change to Overnight margin?

Margin accounts that have lower Intraday futures margins will have the higher Overnight future margin requirements go into effect 15 minutes before the end of that future contract’s designated Regular Trading Hours session. You can monitor the “Look Ahead Available Funds” and the “Look Ahead Next Change” in your Account Window’s Available for Trading section (Click on the green “+” on the right to expand the section). The Look Ahead Next Change time shows the time the Intraday and Overnight margins will change. The Look Ahead Available Funds includes any amount of the change in the margin requirement from Intraday to Overnight margins.

Please Note

  • Cash accounts and IRA accounts (both cash and margin type) are not afforded Intraday margin rates. IBKR can rescind Intraday futures margins due to volatile trading conditions at any time without notice.
