Upon launch, these underlying assets include 4 currencies, 3 energy, and 2 metals products.

These contacts are listed with, and subject to, the rules and regulations of NYMEX.

CME Globex Equity Index Circuit Breaker and Daily Price Limit Changes for Futures and Options
Effective Sunday, April 7, 2013 (trade date Monday, April 8), changes to  circuit breaker methodology and price limits will be introduced on CME Globex for Equity Index futures and options, pending regulatory review periods.

Currently, price limits are established on a quarterly basis based upon the average closing price of the lead month futures contract in December, March, June and September. With this change, the width of the equity index futures price limit band will be calculated daily, based on the underlying cash equity index.

Customers are strongly encouraged to utilize the FIX/FAST Security Status (tag 35-MsgType=f) messages to obtain the daily price limits (tag 332-HighPx; tag 333-LowPx) to avoid the rejection of orders that breach price limit thresholds.

Customers may also obtain the daily price limits from the Security Definition (tag 35-MsgType=d, tag 1149-HighLimitPrice and 1150-LowLimitPrice) messages on the instrument replay feed.

These changes are currently available for customer testing in New Release.
