FutureDefinition

#	Message Name	Description
4335	CCodeDefinition	Commodity code (product code) definitions for all futures. Also maps future ccodes to SpiderRock tickers. Information is sourced from listing exchange product definitions. This table also contains definitions for exchange and user-defined spreads including spreads used as option underliers. SpiderRock typically uses a compact form of the exchange (spread) product ID as the ccode for these products if there is no natural (human-readable) exchange spread ticker issued for the spread. Note that the full spread definition can be found in the ProductDefinition and human-readable version in the description field below. Note that SpiderRock tickers below are synthetic and are created for organizational purposes only. SpiderRock synthetic tickers typically begin with a '@' character.
4360	ProductDefinitionV2	SpiderRock normalized exchange product definitions. Includes future, option, and spread definitions from a number of exchanges. TickerDefinitions, RootDefinitions and CCodeDefinitions are consistent with these records.
