How do I place an outright futures order? (US options and futures)

To place a futures order on the web browser trading platform, begin by entering the futures symbol in the search field or clicking the symbol on your watchlist. Once selected, click on the trade tab on the left side panel, and then toggle the single trading mode. Choose to either buy or sell the asset, set the price, order type, and TIF (time-in-force) as illustrated below.

GTC orders for futures cannot be cancelled when the market is closed or between sessions. For instance, a GTC order on an /ES future cannot be cancelled between 4:00pm-4:50pm CT. During periods when the market is between sessions, orders cannot be cancelled from 4pm CT on Friday until 4:50pm CT on Sunday when order routing for CME futures resumes. Additionally, GTC orders cannot be cancelled during the CME's no-cancel periods, which occur 30 seconds before the market opens at 5pm CT.
