A Clearly Erroneous Execution (CEE) is defined as an execution at a price, for a quantity of shares, or with a symbol, that is substantially inconsistent with the current trading pattern of the issue. CEE Requests for Review are processed using a web-based submission service, designed to expedite and simplify review request entries and to help customers meet submission deadlines.

All NYSE, NYSE MKT, or NYSE Arca Submission Forms, and detailed CEE guidelines and policies are available on the NYSE Euronext Clearly Erroneous Execution landing page.
