You can re-open a round you closed early.
If you have closed and awarded a round but have not progressed to the next round, you must first undo your award before you can re-open the round. If you have progressed to the next round, you cannot alter the previous round.

When re-opening a round, ensure that you first select a date and time in the future using the date picker.
To re-open a round, complete the following steps:
- Go to Bid > Management.
- Set the round to open at a future date.
- In the Re-open Round area, click Show date picker.
- Select a date from the calendar.
- Select the hour.
- Select the minute.
- Click Re-open Round.
If only certain bidders require additional bidding time after a round has closed, you may want to re-open the round to accommodate those specific bidders only. In this case, you can block the bidders who do not require the additional bidding time in the re-opened round. For more information, see Managing bidder access.
