Ring: Ring is a circular area on the trading floor of an exchange where traders and brokers stand while executing futures trades. Some exchanges use pits rather than rings.
Basis: Basis is the difference between the current cash price of a commodity and the futures price of the same commodity. In more details, the Basis is the difference between the spot or cash price of a commodity and the price of the nearest futures contract for the same or a related commodity. Basis is usually computed in relation to the futures contract next to expire and may reflect different time periods, product forms, grades, or locations.
Buyer: Buyer is a market participant (trader/investor) who takes a long futures position or buys an option. An option buyer is also called a taker, holder, or owner.
Clearing Member: Clearing member is a member of an exchange clearinghouse responsible for the financial commitments of its customers (a member of clearing organisation). All trades of a non-clearing member must be registered, processed and eventually settled through a clearing member.
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, clearing association or multilateral clearing organization.
Clearinghouse: Clearinghouse is a corporation or separate division of a futures exchange that is responsible for settling trading accounts, collecting and maintaining margin monies, regulating delivery and reporting trade data. The clearinghouse becomes the buyer to each seller (and the seller to each buyer) and assumes responsibility for protecting buyers and sellers from financial loss by assuring performance on each contract.
Contract: Contract is a term of reference describing a unit of trading for a commodity future or option. At the same time contract is an agreement to buy or sell a specified commodity, detailing the amount and grade of the product and the date on which the contract will mature and become deliverable.
Derivative: A financial instrument, traded on or off an exchange, the price of which is directly dependent upon the value of one or more underlying securities, equity indices, debt instruments, commodities, other derivative instruments, or any agreed upon pricing index or arrangement. Derivatives involve the trading of rights or obligations based on the underlying product but do not directly transfer that product. Derivatives are generally used to hedge risk or to exchange a floating rate of return for fixed rate of return. Derivatives include futures, options, and swaps. For example, futures contracts are derivatives of the physical contract and options on futures are derivatives of futures contracts.
Futures: Futures (also called Futures Contract) is a legally binding agreement to buy or sell a commodity or financial instrument at a later date. Futures contracts are normally standardized according to the quality, quantity, delivery time and location for each commodity, with price as the only variable.
Futures Contract: Futures Contract is an agreement to purchase or sell a commodity for delivery in the future: (1) at a price that is determined at initiation of the contract; (2) that obligates each party to the contract to fulfill the contract at the specified price; (3) that is used to assume or shift price risk; and (4) that may be satisfied by delivery or offset.
Low: Low is the lowest price of the day for a particular futures or options on futures contract.
Margin: Margin is an amount of money deposited by both buyers and sellers of futures contracts and by sellers of options contracts to ensure performance of the terms of the contract (the making or taking delivery of the commodity or the cancellation of the position by a subsequent offsetting trade). Margin in commodities is not a down payment or partial payment on a purchase, as in securities, but rather a performance bond. There are two main types of Margin: initial margin and maintenance margin. Initial margin is the amount of margin required by the broker when a futures position is opened. Maintenance margin is an amount that must be maintained on deposit at all times. In situation when the equity in a customer's account drops to or below the level of maintenance margin because of adverse price movement, the broker must issue a margin call to restore the customer's equity to the initial level. Exchanges specify levels of initial margin and maintenance margin for each futures contract, but futures commission merchants may require their customers to post margin at higher levels than those specified by the exchange. Futures margin is determined by the SPAN margining system, which takes into account all positions in a customer's portfolio.
