Abstract: Systems and methods for trading and clearing eroding futures contracts on an exchange. Eroding futures contracts are futures contracts in which the contract size or open position size is determined as a balance remaining on a contract that is finally settled incrementally over time. The contract includes a delivery process that reflects reduction of contract size (e.g., by financial settlement) during the delivery period until no value remains for the contract.
