Realization | ||
---|---|---|
The p&l of trades (and cash flows) is described as:
Detail Most trades involve delivery at some point in the future Because the value of the commodity to be delivered is not known before the delivery, the value needs to be estimated or calculated from market data. For forwards and futures and other linear trade types the value may be estimated by a simple mark to market calculation For options and other non-linear trades the value may be calculated using the Black 76 method (derived from the earlier Black-Scholes method) We say the trade's value (its p&l) is unrealized because it is not yet known for certain, and is therefore a cause of market risk Once delivery has taken place, we know (or don't care about) the delivered value, the value of he trade is known and no longer varies. In effect the p&l is locked in, there is no more market risk associated with this trade and the p&l is said to be realized The p&l of a trade (or cash flow) moves from unrealized to realized when one or more of the following conditions has been met
Realization is the set of business rules that defines when p&l moves from unrealized to realized based on:
Realization is subjective: different organizations may have different business rules to determine realization | ||
Scheduling | ||
---|---|---|
Often used as a term for the Operational activities involved in gas and power Detail Short term position needs to be nominated or notified to the respective system and market operators:
This set of activities is often collectively referred to as Scheduling The schedule of a trade describes the delivery profile (that will need to be nominated) | ||
Settlement | ||
---|---|---|
The Business Process or Capability covering the payments relating to trading activities. It includes agreeing payments, making them, and ensuring that payments are received at the correct times Detail Settlement includes: We also referred to the concept of financial and physical settlement of trades
We need to be careful to recognize the legal definition of settlement of a physical trade:
Most other parts of energy trading businesses identify the term settlement with cash settlement (or payment) | ||
Shape | ||
---|---|---|
Shape is a term, mainly used in Power Trading to describe a non-continuous delivery over a delivery period For example a UK power trade may have a delivery period of a month and have peak shape, which specifies that the power will be delivered over a time period of 07:00 - 23:00 each day of the Month Detail Typical shapes include

Speculative Trading | ||
---|---|---|
Speculative trading, also known as proprietary or spec. trading, is the trading of commodities with the intent of making a profit with no intent to make or take delivery of those commodities Detail Spec. traders take forward positions, either short or long with the view to closing out those positions at a later date, prior to delivery Closing out the open position involves trading to flatten the net position, eventually (but before delivery) to zero | ||
Spot | ||
---|---|---|
A spot trade in general refers to a trade with immediate delivery. In energy trading terms it usually refers to a trade with delivery on the day it is executed (within day) or for the following day (day ahead) Detail There is usually high volume trading in spots, particularly for power and gas, as speculative traders try and close out their positions as delivery times approach, and asset-backed traders try to balance, and financially optimize their positions. A large proportion of spots are traded on Exchanges and through Brokers Spot trades are settled physically, and even if executed on an Exchange are often settled by invoice and payment within a day or two of delivery | ||
Spread | ||
---|---|---|
A spread is a difference in price, or value, of two similar but different underliers An Energy Spread trade s a type of trade between two floating prices on similar but not identical energy underliers Detail Spread trades are usually financially settled Different types of Energy Spread are classified by the difference in the underliers:
Many commodity spreads are associated with the cost of generating electricity, so they involve electricity as one commodity, the others may be:
Another group of commodity spreads are associated with the cost of refining, so they involve crude oil as one commodity, the others being refined products such as gasoline. These are known as crack spreads Spread is also used to describe the difference in prices between locations, times, commodities

Storage | ||
---|---|---|
A type of commodity, which although it may be applied to any physical commodity, usually describes the ability to store natural gas in its gaseous state Storage facilities usually consist of natural structures (depleted gas fields for example) that are attached to the gas pipeline network Details Storage may be bought from the Storage operators in auctions or traded Storage allows the option to inject gas into storage, or release gas from storage The commercial use of storage is generally to allow gas to be transferred into Storage (injected) in Summer months when the prices are low, and released (withdrawn) in the peak Winter months when gas prices are high Storage behaves somewhat like an option on a physically settled time spread | ||
Swing Contract | ||
---|---|---|
Also known as a swing option, a swing contract is a type of contract that allows the buyer the option, but not the obligation, to take periodic deliveries of a product at a volume nominated by them between a minimum and a maximum volume at an agreed price Detail Swing contracts ate typically used in long term supply contracts of gas, oil and power They are frequently combined with a take or pay clause, which specifies that a minimum amount of product must be taken over a set of long periods e.g. A swing contract may specify that a daily volume between 10 and 100 units may be taken each day A take or pay clause may specify that a minimum of 365 * 15 units may be taken over the entire year Daily nominations of swing contracts are usually made by a particular time on the previous day, and may be transmitted electronically Valuation of swing contracts is extremely complex, because of the daily optionality, and particularly if there is a take or pay clause as the overall delivery is constrained Swing contracts may be short or long term (up to twenty-five years). Typically the price is either renegotiated periodically, or indexed to an index, or a basket of indexes | ||
Take or Pay | ||
---|---|---|
A type of supply contract in which the buyer commits to buying a minimum quantity of some product, or to make an alternative payment for the amount below the minimum quantity Take or Pay contracts are widely used in the Gas and Oil markets Detail The minimum quantity, the price of purchase, and the price paid for any amount below the minimum are all defined in the contract Typically the buyer nominates a delivery volume each day from the supplier, the minimum quantity applies over a year | ||
