Paper Trading Order Processing Disruption

Resolved on September 14, 2026.

resolved Sep 14, 2026, 09:00 PM UTC

We identified an issue affecting a subset of paper trading order processing caused by a stale asset reference following a corporate action on an underlying symbol. This led to intermittent failures for a portion of paper trading traffic. The affected orders have been identified and cleared, and impacted accounts have been refreshed. Order processing has stabilized and we are continuing to monitor.
