Catastrophic Error Fee Cut to $500

Effective September 1, 2026, the Exchange will remove the $5,000 charge that applied in connection with an initial catastrophic error review. Instead, if the Obvious Error Panel or Catastrophic Error Panel votes to uphold the decision on appeal, the Trading Permit Holder who requested the appeal will be charged $500.

Pass-Through of Other Market-Center Charges

Effective September 1, 2026, when the Exchange requests a determination from another market center that a transaction is clearly erroneous, the Exchange will pass any resulting charges from that market center through to the relevant Trading Permit Holder. This means Trading Permit Holders may be billed for charges imposed by other venues in those cases.
