发明名称 SYSTEMS AND METHODS FOR PROVIDING A LIQUIDITY-BASED COMMODITIES INDEX
摘要 Systems and methods are provided for a liquidity-based commodity index in which historical liquidity-related data for a commodity is used to determine whether to include a commodity in an index and also used to weight commodities in the index. Liquidity of a commodity is calculated based on an average daily dollar value of contracts traded for the commodity. The commodity liquidity is compared to a liquidity threshold to determine that the commodity should be included in the index. A liquidity factor is calculated for each commodity included in the index and is also used to weight the commodity in the index.
