Can I keep a position open through a high-impact news event on my Funded account?

Yes. The news holding rule allows you to keep a position open through a high-impact news event, provided the position was opened before the 2-minute pre-news window began. You may then close it any time after the 2-minute post-news window has passed. What you cannot do during the window (2 minutes before to 2 minutes after) is open new positions, close existing ones, or trigger pending orders. If you entered your trade before the window opened, you are free to hold it through the event.
