Following the U.S. Memorial Day holiday weekend, some accounts that sold U.S. equities on Friday, May 22 experienced a delay in withdrawable cash being updated on Tuesday, May 26. The issue was identified at 4:25 AM ET, and corrections were applied to all affected accounts. The incident was fully resolved by 8:03 AM ET. Trading, order entry, and the market open were not impacted, and settlement dates in the ledger remained accurate throughout. We are implementing changes to help prevent this from recurring ahead of the next U.S. market holiday on June 19.
