Abstract:
1. A method for calculating a value associated with buying and selling a sector index comprising a plurality of tradeable objects being traded on an electronic exchange, the method comprising: receiving at a computer device market information corresponding to each of the plurality of tradeable objects corresponding to the sector index, the market information comprising a last traded price, a last traded quantity for each tradeable object, and an inside market with a highest bid price and a lowest ask price currently available for each tradeable object; comparing at the computer device the last traded price to the inside market for each tradeable object to determine if a last trade for each tradeable object occurred on a bid side or on an ask side based on received market information; determining at the computer device a current running total volume for each tradeable object by adding or subtracting the last traded quantity to or from a preceding running total volume, based on the determination of whether the last trade occurred on the bid side or on the ask side; and determining at the computer device a current running total volume for the sector index using the current running total volume for each tradeable object and a weight value assigned to each of the plurality of tradeable objects within the sector index.
