Definitions

  • a traditional futures exchange is a membership structure that allows trading only through members.
  • Traditional markets have customers, members and clear members.
  • the financial backing of a traditional exchange is also through members.
  • Members provide capital and when a trade is completed a clearing member will back the trade.
  • Some exchanges only allow their clearing members to trade.
  • Other exchanges allow any person to trade as long as a clearing member backs the person. That is, a clear member can have customers that have accounts with the clear member. The customer uses the credit of the clear member to trade and the customer does not have direct access to the market.

  • the relationships are represented as market participants that include a subscriber 12, guarantor 14, and trader 16.
  • the market participants interact through a system 11. All three types of market participants have contractual relationships with the exchange 10 and are screened by an accrediting agency, e.g., the National Futures Association (NFA) for a US-based exchange (or equivalent) for disciplinary and financial soundness.
  • Subscribers 12 identify one or more guarantors 14 who provide access to financial resources used for margin. Subscribers also identify one or more traders 16 who are eligible to enter orders for the subscriber's benefit. In some instances the subscriber 12, guarantor 14, and/or trader 16 may be the same entity.
  • the system 11 will be described in more detail below. Suffice it here to say that the system 11 includes computer systems 22 and storage devices 24 that store trading accounts 18 and the processes 25 used to implement the electronic futures exchange 10.

  • a subscriber 12 is the economic beneficiary of the trading that occurs on its behalf. Subscribers 12 may be natural persons or other legal entities. All subscribers 12 are subject to the provisions of an exchange subscriber agreement. Subscribers 12 identify assets acceptable to the exchange 10 that can be used for margin to support positions.
  • the exchange 10 maintains at least one trading account 18 for each subscriber.

  • Subscribers 12 may have multiple trading accounts for multiple guarantors (not shown) . Examples of subscribers 12 might include a customer of a futures commodities market (FCM) , a corporation or financial institution, or a commodity pool. Positions held by a subscriber are associated with the exchange subscriber trading account 18. Each subscriber trading account 18 will also identify assets that provide margin for the positions held in that account. Positions are determined by product species that a trader 16 can trade on.

In particular, exchange 10 has the right to satisfy all margin obligations by contacting the guarantor and demanding payment. Failure of the guarantor 14 to provide timely payment would constitute a default on the part of the subscriber.
  • Guarantors 14 can restrict the markets traded by a subscriber.- Examples of a guarantor might include an FCM, bank, credit card facility, other financial institution, or a large corporation. In some instances the guarantor may be a subscriber.
  • a subscriber can maintain the trading account 18 and assets at a registered FCM, where the subscriber's funds will be segregated in accordance with CFTC requirements.
  • the FCM will be considered the guarantor of its subscriber' s trading account 18.
  • a subscriber's trading account 18 can be guaranteed by a third-party, credit worthy institution, including a bank, broker dealer, or corporate entity. The guarantee relationship can be documented by a letter of credit or comparable agreement that allows the exchange 10 to have recourse against the guarantor in the event that the subscriber fails to perform its financial responsibilities, including initial margin and variation margin obligations up to a specified limit.
  • a self-guaranteeing subscriber is a corporation or other entity that has sufficient credit worthiness to bear the financial obligations of trading without requiring a third party's guarantee.
  • the exchange 10 or other entity performs financial surveillance of self-guaranteeing subscribers 12 in order to maintain a high level of confidence and to deter abuse.

  • a trader 16 enters orders on behalf of a subscriber 12. Traders 16 are natural persons.
  • either the subscriber or its guarantor authorizes a trader 16 to enter orders for a subscriber's trading account 18. Without such authorization, a trader 16 cannot enter orders in the exchange 10. Examples of traders 16 might include the subscriber, a commodity trading advisor, an FCM order-entry clerk, or an employee of the subscriber. Several subscribers 12 may authorize the same trader 16 (e.g., a commodity trading advisor) . Also, several traders 16 may be authorized for the same subscriber (e.g., employees of a corporation). Each category of trader 16 will be identified so that exchange 10 and/or the National Futures Association can perform trade practice surveillance 19. Traders will have account access privileges, a trading profile, and trading limits 17 that are reflected in the trading account 18.
  • the exchange 10 uses the market structure 10 described above in an Internet-based on-line trading system 11 having real-time clearing 30 and risk management 32 functions. Because all three types of market participants are known to the exchange 10, risk management 32, compliance and functions, 34 of the exchange 10 can be applied to any or all of the participant types.

Additionally, non-browser user interface clients (not shown) capable of communicating with the exchange trading system 60 may be used. Generally, subscribers 12 and guarantors 14 will not have access to the trading system 40 for trading purposes. However, for risk management purposes, subscribers 12 and guarantors 14 may authorize system access to individuals in their control with supervisory responsibilities. The exchange 10 can permit a single trader 16 to have several sessions open at the same time. Once logged on, a trader 16 may enter orders for any trading account 18 for which the trader 16 has permission to trade.

  • the exchange 10 includes a matching engine 150 that works with the order types and qualifiers, as shown in TABLE 2 below.
  • the matching engine 150 receives 152 an order and attempts to match 154 the received order with orders on the opposite side of the market that are queued within an order book 155 in the system in accordance with a priority as set forth below. If the system can form a match 156, the match is returned 158. Otherwise, if the system cannot form a match, the system determines 160 whether there are more potentially matchable orders on the opposite side of the market that can be matched to the received order. If there are additional orders, the process will fetch 162 the next order. Otherwise, the process will store 164 the order in the order book in a priority, as specified below. TABLE 2
  • the matching process 154 determines 154a whether the received order and an order are at the opposite side of the market fetched from the order book have the same level of specificity. If the orders have the same level of specificity 154b, the orders are passed to a conventional matching process 154c to match the order in accordance with price time priority as would be currently performed on a typical futures market exchange. However, if the process 154 determines 154a that the received order is more generic than the order from the order book 154d, and further determines 154e that the received order is enabled for more specific matching, then the received order will be sent to the matching process 154c to match positions with the order from the order book.
  • orders match 154f the positions are recorded in each trading account 18 with the degree of specificity on the order that was in the order book and the match is returned 154g. If the orders do not match, the received order will be tested 154f against other orders in the order book as above. If the orders in the order book do not match the received order, the received order will be placed in the order book, as described above, in accordance with time price priority considerations described below.
  • the process determines 154h whether the queued order is enabled 154i for more specific matching. If the queued order is enabled for more specific matching the orders are sent to the matching engine 154c. If there is a match, the positions are recorded in each trading account 18 associated with the orders, with the degree of specificity as set forth on the received order. Otherwise, if there are no orders that match the received order, the received order is placed in the order book.
  • Each contract genus can use either a price-time or pro-rata order-matching algorithm to find matching, offsetting orders. Trades are executed at the best available price. If there are multiple orders at the same price, the earlier-posted order has priority. Orders are entered into a contract genus order book. If the order contains all the elements necessary to completely define a contract species then it is a candidate for matching with an offsetting order at the other side of the market. For example, a trader 16 can place an order for benzene futures as specified in the example in above. If the trader 16 places the order to include all of the Grade (e.g., astm 2359), Delivery Location (e.g., Houston), and Delivery Month (e.g., July 2000) parameters it would be considered fully specified. Such an order could be matched against an offsetting order that referred to the same set of fully specified parameters. Orders matched in this manner are analogous to the procedures used in conventional futures order matching.
  • Grade e.g., astm 2359
  • the matching algorithm supports matching orders across contract species.
  • Multi-species order matching rules are shown in TABLE 3. Such an order can be entered into the contract genus order book, without all the elements necessary to completely define a contract species.
  • a trader 16 can place an order for Benzene as specified above. If the trader 16 places the order to include the Grade (e.g., astm 2359) and Delivery Month (e.g., July 2000) parameters, but indicates the Delivery Location as ANY, it would NOT be considered fully specified. This order could be matched against an offsetting order that also contained ANY as the Delivery location parameter.
  • the exchange 10 allows a trader 16 to specify that an order be matched against more specific orders.
  • an order be matched against more specific orders.
  • Multiple and cross contract species matching impacts position offset rules. If a trading account 18 has both specified and unspecified positions in it, position offset will depend on whether the long or short is more highly specified, and whether the long or short determines actual delivery terms.
  • a position offsetting process 180 is shown.
  • the process 18 assumes that the short interests sets unspecified contract terms at the time of contract delivery.
  • the position offsetting process 180 is used to offset positions from a common trader 16 or a common subscriber in a common market.
  • the position offsetting process 180 determines 182 whether the subscriber has a long position and a short position in the market.
  • the process also determines 184 the relative specificity of the positions. If a long position in a market has the same specificity 186 as a short position in the market, and if so, the positions are set 186 to offset and the offsetting positions are recorded 188 in the trading account 18 of the trader 16.
  • the positions will not offset since the exchange cannot determine that the remaining positions will result in a correct match between short and long positions at delivery time. However, if the long position is more specific 192 than the short position, the positions will offset upon trader instruction 194 since the exchange 10 can be certain that the remaining positions will result in a correct match between short and long positions at delivery time. TABLE 4 shows offset rules .
  • the Exchange 10 can permit certain trades to be matched away from the exchange 10 order book. In particular EFPs, Block Trades, and other adjustments can be posted to the exchange clearing system without passing through the exchange's matching engine.
  • Exchange of futures for physicals (EFPs) and block trades are particular trades that can be done outside of the trade matching system, but which are entered into the trading system after they take place.
  • Both parties to the trade report an EFP or block trade to the exchange 10 so that open interest and position information can be updated accordingly.
  • the exchange 10 verifies that sufficient assets are available in each subscriber's trading account 18 before allowing the trade to be cleared.
  • An ex-pit is a notification of a change to an already cleared trade. Changes may include the subscriber to whom the trade was attributed; the price at which the trade was executed; or the quantity traded. Both sides of the original trade need to agree to price and quantity changes. EFPs, ex-pits and block trades are recorded as special trade types. Ex-pits transactions generally are not broadcast to the entire market. The exchange compliance system monitors these trades to ensure that they comply with exchange rules.
  • Confirmation messages are generated upon order entry and execution.
  • the Exchange 10 can electronically deliver messages via, E-mail, fax, beeper, personal assistant, etc.
  • the messages are sent to the executing trader 16 and to the subscriber for whom the order was placed. Messages may be sent to the guarantor or others upon request.
  • Orders may be modified prior to being matched. If an order is modified, it loses its position in the order book unless the modification is to lower the order quantity. Orders may be canceled for any unsatisfied portion before being matched. In certain risk management circumstances, exchange 10 can suspend an order by indicating the order as System Held. Suspended orders remain in the order book, but they are not available for matching. If a held order is reactivated, it retains its original time priority.

There are default thresholds that may be changed for each and every entity at the discretion of the exchange 10. Thresholds include total positions, net positions, total dollar holdings, market concentrations, and asset value changes. Risk fluctuates several ways for a given trading account. For example, positions held in the account may change in value, the assets held in the account may change in value, and the exchange 10 may increase margin rates, which will require additional funds to be deposited.

  • Assets may be placed in or released from a subscriber's trading account 18 at any time provide that a release will not bring assets below a required margin amount. Assets will be recorded in face amounts (when appropriate) , and in equivalent value to reflect the capital charge applied to each asset.
