Delta Margining

See Also:

Delta: Delta is the expected change in an option's price given a one-unit change in the price of the underlying futures contract or physical commodity. For example, an option with a delta of 0.5 would change $.50 when the underlying commodity moves $1.00.

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.

Call: There are three meaning of the "Call" term. It could be:
1) An option contract giving the buyer the right but not the obligation to purchase a commodity or other asset or to enter into a long futures position;
2) a period at the opening and the close of some futures markets in which the price for each futures contract is established by auction;
3) the requirement that a financial instrument be returned to the issuer prior to maturity, with principal and accrued interest paid off upon return.

Called: Called is 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.

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.

Exchange: A central marketplace with established rules and regulations where buyers and sellers meet to trade futures and options contracts or securities. Exchanges include designated contract markets and derivatives transaction execution facilities.

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.

Option: Option is a contract that gives the buyer the right, but not the obligation, to buy or sell a specified quantity of a commodity or other instrument at a specific price within a specified period of time, regardless of the market price of that instrument. There are two types of options: Put Options and Call Options.

Option Premium: Option Premium is the price a buyer pays (and a seller receives) for an option. Premiums are arrived at through the market process. There are two components in determining this price-extrinsic (or time) value and intrinsic value.

Underlying Futures Contract: Underlying Futures Contract is a specific futures contract that the option conveys the right to buy (in case of a call) or sell (in the case of a put).
