Effective Sunday, November 21, 2004, CME will have the ability to send “Insert” messages (Type Code “I”) from CME Globex over Channel 2 of the CME Market Data Network (MDN).  Unlike quotes coming from the Regular Trading Hours (RTH) session on Channel 1 of the MDN where we transmit both “Insert” and “Delete” messages, we have been transmitting “Delete” messages from CME Globex all along, but have never sent “Insert” messages previously.

If needed, CME will now have the capability to make adjustments of prices from CME Globex.
