Symbols for a specific delivery period have the following format:
<RootSymbol><Sequence_ID><Contract_Split_MN><Begin Delivery Month or End Delivery Month><Year>.<CustomerID>
Where:
Root Symbol = DTN Root Symbol
Sequence_ID = 2 Digit Sequence Id
Valid range (1-99) and starts with 01, normally. If bids are created using different end delivery date within the same contract split month, will result with a new sequence ID to identify this new bid as unique.
Contract_Split_MN = Contract Split Month
Contract Split Month: possible values: 0, 1, or 2
0 = Difference between start delivery date & end delivery date is greater than 26
1 = End delivery date’s day is less than 15
2 = Value wouldn’t result into 0 or 1
Contract_MN = Contract Month (1 character)
Standard month codes for futures
Contract_YR = 2 digit contract year
Examples
Bid from ElevatorID 3451 for Yellow Corn (CY) with contract split month of 0 sequence id of 1 contract month of September and year of 10 would result in: CY010U10.3451
Bid to CustomerId 3451 for Corn yellow with contract split month of 1 sequence id of 1 contract month of September and year of 10 and start, end delivery date of 09/01/2010, 09/10/2010 would result in: CY011U10.3451
If another bid for the same as the above-mentioned except start & end delivery date of 09/11/2010, 09/15/2010, would have resulted in the same quote symbology hence making both bids the same. Instead the bumped sequence id would result into the new symbol and unique bid: CY020U10.3451
