This extension covers part of the SEC amendments for Regulation SHO to place further restrictions on short selling. See also EP120.

Since the SEC amendment provides exemptions to the rule (broker/dealers may submit “short exempt” orders under certain conditions), it is necessary to enhance FIX messages during the trade lifecycle. In particular, a FIX order message must be able to indicate whether the order is exempt from the rule. Furthermore, execution and trade reporting messages need to be able to convey the reason for the exemption.

This extension covers part of the SEC amendments for Regulation SHO to place further restrictions on short selling. See also EP121.

The rules create a “Circuit Breaker” which changes the trading behavior for a security. FIX is utilized in pre-trade dissemination of securities reference data and market data; it follows that FIX needs a method to disseminate whether this Circuit Breaker is triggered for a given security, as well as a method for a user to query whether the Circuit Breaker is in effect.
