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.
