A newly posted pre-market listing is active for 48 hours and it cannot be extended beyond the auto-expiration date unless it is linked to a SDAR active on-market listing. Pre-market listings auto expire after 48 hours and will be automatically removed from both the SDAR & public view.
You will receive an email notification 24 hours before the listing expires. You will also receive an email notification the day your listing expires.
In-platform notifications will also remind you to update your pre-market listings. Click on the bell icon in the top navigation bar to see a list of your recent notifications:
