No stock should trade +/-15% from the close price or the effective close price at the opening of the market. The effective close price is determined whenever the closing bid is greater than the close price or whenever the closing ask is less than the close price. Use the closing bid as the effective close price, if the value is greater than the close price or use the closing ask as the effective close price, if the value is less than the close price. However, during the day if the Circuit Breaker is triggered for a security, the security will be halted for an hour to allow for the release, circulation and absorption of any relevant market news and a cool down period while investors consider their options. After the hour has passed the security will be released for trading and the new reference price, which is a simple average of the trigger price and the close price, will be used to determine the trade range for the remainder of the day. The price of the trade that triggered the Circuit Breaker should not be +/-15% outside of the original prescribed price band. The stock will not be allowed to trade +/- 15% of the new reference price.
