Updated 2026-04-30blackoutstradingcompliance
Blackout windows prevent officer and director trading during periods of material non-public information.
When they apply
- Quarter-end through 2 business days after earnings release.
- 30 days before any 10-K, 10-Q, or material 8-K.
- During any internal investigation or material development.
- Custom periods you define.
What the system does
When an officer attempts to log a Form 4 transaction during a blackout, the system blocks with a hard error. The error includes the blackout reason and the unlock date.

Pre-clearance
For 10b5-1 plan trades, pre-clearance is automatic if the trade is within an active 10b5-1 plan and the cooling-off period has elapsed.
Notifications
Officers receive an email 7 days before each blackout begins and 1 day before it ends. The notification includes the dates and the affected accounts.
