Front-month symbols will remain unchanged. NOTICE: DTN.IQ users who have workspaces or watchlists setup using the month/year code symbols for these symbols will need to update thier workspaces and watchlists to the new symbology! Examples: Currently the symbol for the CORN MAR 2010 contract is CH0. On January 31, 2010 this symbol will become CH10 Currently the symbol for CORN MAR 2010 Call at 110.00 is CH0C1100. On January 31, 2010 this symbol will become CH10C1100 Currently the symbol for CORN MAR 2010 / SEP 2010 spread is CH0-CU0. On January 31, 2010 this symbol will become CH10-CU10 Currently the Symbol for the CORN Front-month contract is C#. This will remain unchanged and continue to be C# after the transition.

DTN_Jay_Froscheiser -VP, Product Operations- Posts: 1746 Joined: May 3, 2004 DTN IQFeed/DTN.IQ/DTN NxCore	Posted: Mar 12, 2010 11:07 AM Msg. 3 of 3 In order to ensure the best support for futures, futures options and spreads contracts that trade further out than 10 years, DTN.IQ/IQFeed has transitioned its futures symbology to a 2-digit year-code format. Although this change was released to customers on March 1, 2010, we have continued to support the old 1-digit year-code format in order to provide a smooth transition for our customers and 3rd party software providers. Effective April 5, 2010, DTN.IQ/IQFeed will only support the new 2-digit year-code symbology. In order to ensure your charts, watch lists, spreadsheets, etc continue to function beyond April 5, please modify your software to utilize this new symbology now. Using the older 1-digit year-code symbols after April 5 will cause you to receive an "Invalid Symbol" or similar error. Examples: If you currently use @ESM0, you must change to @ESM10 If you currently use QCLJ0, you must change to QCLJ10 If you currently use @CZ1, you must change to @CZ11 If you currently use +CK0, you must change to +CK10 If you currently use any "front month" symbology that ends in "#", there is no change needed.
