Calendar Spread: (1) The purchase of one delivery month of a given futures contract and simultaneous sale of a different delivery month of the same futures contract; (2) the purchase of a put or call option and the simultaneous sale of the same type of option with typically the same strike price but a different expiration date. Also called a horizontal spread or time spread.
Call: (1) An option contract that gives the buyer the right but not the obligation to purchase a commodity or other asset or to enter into a long futures position at a specified price on or prior to a specified expiration date; (2) formerly, a period at the opening and the close of some futures markets in which the price for each futures contract was established by auction; or (3) the requirement that a financial instrument such as a bond be returned to the issuer prior to maturity, with principal and accrued interest paid off upon return. See Buyer’s Call, Seller’s Call.
Called: Another term for exercised when an option is a call. In the case of an option on a physical, the writer of a call must deliver the indicated underlying commodity when the option is exercised or called. In the case of an option on a futures contract, a futures position will be created that will require margin, unless the writer of the call has an offsetting position.
Call Rule: An exchange regulation under which an official bid price for a cash commodity is competitively established at the close of each day's trading. It holds until the next opening of the exchange.
Cap and Trade: A market based pollution control system in which total emissions of a pollutant are capped at a specified level. Allowances are issued to firms and can be bought and sold on an organized market or OTC.
Capping: Effecting transactions in an instrument underlying an option shortly before the option's expiration date to depress or prevent a rise in the price of the instrument so that previously written call options will expire worthless, thus protecting premiums previously received. See Pegging.
Carrying Broker: An exchange member firm, usually a futures commission merchant, through whom another broker or customer elects to clear all or part of its trades.
Carrying Charges: Also called Cost of Carry. Cost of storing a physical commodity or holding a financial instrument over a period of time. These charges include insurance, storage, and interest on the deposited funds, as well as other incidental costs. It is a carrying charge market when there are higher futures prices for each successive contract maturity. If the carrying charge is adequate to reimburse the holder, it is called a "full charge." See Negative Carry, Positive Carry, and Contango.
Carry Trade: A trade where one borrows a currency or commoidity commodity or currency with a low cost of carry and lends a similar instrument with a high cost of carry in order to profit from the differential.
Cascade: A situation in which the execution of market orders or stop loss orders on an electronic trading system triggers other stop loss orders which may, in turn, trigger still more stop loss orders. This may lead to a very large price move if there are no safety mechanisms to prevent cascading.
Cash Market: The market for the cash commodity (as contrasted to a futures contract) taking the form of: (1) an organized, self-regulated central market (e.g., a commodity exchange); (2) a decentralized over-the-counter market; or (3) a local organization, such as a grain elevator or meat processor, which provides a market for a small region.
Cash Settlement: A method of settling futures options and other derivatives whereby the seller (or short) pays the buyer (or long) the cash value of the underlying commodity or a cash amount based on the level of an index or price according to a procedure specified in the contract. Also called Financial Settlement. Compare to Physical Delivery.

Certificated or Certified Stocks: Stocks of a commodity that have been inspected and found to be of a quality deliverable against futures contracts, stored at the delivery points designated as regular or acceptable for delivery by an exchange. In grain, called "stocks in deliverable position." See Deliverable Stocks.
Changer: Formerly, a clearing member of both the Mid-America Commodity Exchange (MidAm) and another futures exchange who, for a fee, would assume the opposite side of a transaction on MidAm by taking a spread position between MidAm and the other futures exchange that traded an identical, but larger, contract. Through this service, the changer provided liquidity for MidAm and an economical mechanism for arbitrage between the two markets. MidAm was a subsidiary of the Chicago Board of Trade (CBOT). MidAm was closed by the CBOT in 2003 after MidAm contracts were delisted on MidAm and relisted on the CBOT as Mini contracts. The CBOT continued to use changers for former MidAm contracts traded on an open outcry platform.
Cheapest-to-Deliver: Usually refers to the selection of a class of bonds or notes deliverable against an expiring bond or note futures contract. The bond or note that has the highest implied repo rate is considered cheapest to deliver.
Circuit Breakers: A system of coordinated trading halts and/or price limits on equity markets and equity derivative markets designed to provide a cooling-off period during large, intraday market declines. The first known use of the term circuit breaker in this context was in the Report of the Presidential Task Force on Market Mechanisms (January 1988), which recommended that circuit breakers be adopted following the market break of October 1987.
Class (of options): Options of the same type (i.e., either puts or calls, but not both) covering the same underlying futures contract or other asset (e.g., a March call with a strike price of 62 and a May call with a strike price of 58).
Clearing Organization: An entity through which futures and other derivative transactions are cleared and settled. It is also charged with assuring the proper conduct of each contract’s delivery procedures and the adequate financing of trading. A clearing organization may be a division of a particular exchange, an adjunct or affiliate thereof, or a freestanding entity. Also called a clearing house, multilateral clearing organization, centralized counterparty, or clearing association. See Derivatives Clearing Organization.
