Once the Community Round has a close date, you'll receive a 5-day notice. In addition, you will see a 7-day countdown on the Community Round page. You have up until the Community Round closes to cancel.

Once the minimum funding target is met, some companies do a "rolling close," where investments that have successfully applied are executed, and funds are transferred. However, the Community Round is still open to receive new investments. 

You'll still receive a five-day notice when any close is about to happen.
