The definition above is the short version. A full explanation — how it works, a worked example and the exam traps — is still being written. In the meantime the chapter below covers it in context.

Written up from the same chapter

• Base priceThe reference price a contract starts each trading day from — the theoretical futures price on the day it is introduced, and the previous day's daily settlement price on every day after.
• Central counterpartyThe clearing corporation that interposes itself in every exchange trade, becoming buyer to every seller and seller to every buyer, so neither side carries the other's credit risk.
• ConvergenceThe certainty that a futures price and the spot price of its underlying meet at expiry — because on the last trading day the contract settles at the cash market price, leaving no room for a difference.
• Credit Default SwapA contract in which a protection buyer pays a regular premium to a protection seller, who agrees to pay any loss in value on a specified reference obligation if a credit event such as default occurs.
• Daily Settlement PriceThe price at which every open futures position is marked and reset at the end of each day — the last 30 minutes' volume weighted average price of that contract, computed separately for each expiry.
• DerivativeA contract whose value is derived from the value of something else — the underlying — rather than from anything the contract itself owns or produces.
