The derivatives market is the financial market for derivatives - financial instruments like futures contracts or options - which are derived from other forms of assets .
66-637: The Chicago Mercantile Exchange ( CME ) (often called " the Chicago Merc ", or " the Merc ") is a global derivatives marketplace based in Chicago and located at 20 S. Wacker Drive. The CME was founded in 1898 as the Chicago Butter and Egg Board , an agricultural commodities exchange. For most of its history, the exchange was in the then common form of a non-profit organization, owned by members of
132-575: A FireWire hub is used) computer networks . Specifically, RFC 2734 specifies how to run IPv4 over the FireWire interface, and RFC 3146 specifies how to run IPv6 . Mac OS X, Linux , and FreeBSD include support for networking over FireWire. Windows 95 , Windows 98 , Windows Me , Windows XP and Windows Server 2003 include native support for IEEE 1394 networking. Windows 2000 does not have native support but may work with third party drivers. A network can be set up between two computers using
198-472: A Sony camera being the only notable user. A project named IEEE P1394d was formed by the IEEE on March 9, 2009 to add single-mode fiber as an additional transport medium to FireWire. The project was withdrawn in 2013. Other future iterations of FireWire were expected to increase speed to 6.4 Gbit/s and additional connectors such as the small multimedia interface. Full support for IEEE 1394a and 1394b
264-476: A build-to-order option on some models since 1997), and most Apple Macintosh computers manufactured in the years 2000 through 2011 included FireWire ports. However, in February 2011 Apple introduced the first commercially available computer with Thunderbolt . Apple released its last computers with FireWire in 2012. By 2014, Thunderbolt had become a standard feature across Apple's entire line of computers (later with
330-447: A certain percentage to isochronous data and the rest to asynchronous data. In IEEE 1394, 80% of the bus is reserved for isochronous cycles, leaving asynchronous data with a minimum of 20% of the bus. FireWire uses Data/Strobe encoding (D/S encoding). In D/S encoding, two non-return-to-zero (NRZ) signals are used to transmit the data with high reliability. The NRZ signal sent is fed with the clock signal through an XOR gate , creating
396-522: A device can pull about 7 to 8 watts from the port; however, the voltage varies significantly from different devices. Voltage is specified as unregulated and should nominally be about 25 volts (range 24 to 30). Apple's implementation on laptops is typically related to battery power and can be as low as 9 V. An amendment, IEEE 1394a, was released in 2000, which clarified and improved the original specification. It added support for asynchronous streaming , quicker bus reconfiguration, packet concatenation , and
462-416: A major technical improvement, namely new port specification that provides 800 Mbit/s over the same 8P8C (Ethernet) connectors with Category 5e cable , which is specified in IEEE 802.3 clause 40 ( gigabit Ethernet over copper twisted pair ) along with a corresponding automatic negotiation that allows the same port to connect to either IEEE Std 1394 or IEEE 802.3 ( Ethernet ) devices. In December 2007,
528-645: A military and aerospace databus network in those vehicles. AS5643 is utilized by several large programs, including the F-35 Lightning II , the X-47B UCAV aircraft, AGM-154 weapon and JPSS-1 polar satellite for NOAA. AS5643 combines existing 1394-2008 features like looped topology with additional features like transformer isolation and time synchronization, to create deterministic double and triple fault-tolerant data bus networks. FireWire can be used for ad hoc (terminals only, no routers except where
594-655: A new focus on commodities beyond butter and eggs, including potatoes, onions, and cheese. In 1972, CME introduced the first financial futures market, offering contracts on seven foreign currencies. By the 2000s, CME had expanded to offer four core financial instruments: commodities, foreign exchange, interest rates, and stock indexes. As of 2022, CME operates under CME Group, which offers a number of derivatives products, including commodities, equity indices, foreign exchange, interest rates, and weather. For example, as of 2017, agricultural contracts were offered on products such as wheat, corn, soybeans, and lean hogs . In metal futures,
660-450: A number of PC desktops, and other small FireWire devices. The 4-conductor connector is fully data-compatible with 6-conductor alpha interfaces but lacks power connectors. IEEE 1394b-2002 introduced FireWire 800 (Apple's name for the 9-conductor S800 bilingual version of the IEEE 1394b standard). This specification added a new encoding scheme termed beta mode which allowed compliant devices to operate at 786.432 Mbit/s full-duplex . It
726-417: A number of companies, primarily Sony and Panasonic . It is most commonly known by the name FireWire (Apple), though other brand names exist such as i.LINK (Sony), and Lynx ( Texas Instruments ). The copper cable used in its most common implementation can be up to 4.5 metres (15 ft) long. Power and data is carried over this cable, allowing devices with moderate power requirements to operate without
SECTION 10
#1732758438928792-557: A power-saving suspend mode . IEEE 1394a offers a couple of advantages over the original IEEE 1394–1995. 1394a is capable of arbitration accelerations, allowing the bus to accelerate arbitration cycles to improve efficiency. It also allows for arbitrated short bus reset, in which a node can be added or dropped without causing a big drop in isochronous transmission. 1394a also standardized the 4-conductor alpha connector developed by Sony and trademarked as i.LINK , already widely in use on consumer devices such as camcorders, most PC laptops,
858-594: A rapid pace since the last triennial survey was undertaken in 2004. Notional amounts outstanding of such instruments totalled $ 516 trillion at the end of June 2007 (according to the Bank for International Settlements [7] ), 135% higher than the level recorded in the 2004 survey (Graph 4). This corresponds to an annualised compound rate of growth of 34%, which is higher than the approximatively 25% average annual rate of increase since positions in OTC derivatives were first surveyed by
924-490: A separate power supply. FireWire is also available in Cat 5 and optical fiber versions. The 1394 interface is comparable to USB . USB was developed subsequently and gained much greater market share. USB requires a host controller whereas IEEE 1394 is cooperatively managed by the connected devices. FireWire is Apple's name for the IEEE 1394 High Speed Serial Bus. Its development was initiated by Apple in 1986, and developed by
990-489: A single standard FireWire cable, or by multiple computers through use of a hub. This is similar to Ethernet networks with the major differences being transfer speed, conductor length, and the fact that standard FireWire cables can be used for point-to-point communication. On December 4, 2004, Microsoft announced that it would discontinue support for IP networking over the FireWire interface in all future versions of Microsoft Windows . Consequently, support for this feature
1056-412: A strobe signal. This strobe is then put through another XOR gate along with the data signal to reconstruct the clock. This in turn acts as the bus's phase-locked loop for synchronization purposes. The process of the bus deciding which node gets to transmit data at what time is known as arbitration . Each arbitration round lasts about 125 microseconds. During the round, the root node (device nearest
1122-527: A superseding standard, IEEE 1394-2008 . The features individually added give a good history on the development path. The original release of IEEE 1394-1995 specified what is now known as FireWire 400. It can transfer data between devices at 100, 200, or 400 Mbit/s half-duplex data rates (the actual transfer rates are 98.304, 196.608, and 393.216 Mbit/s, i.e., 12.288, 24.576 and 49.152 MB/s respectively). These different transfer modes are commonly referred to as S100, S200, and S400. Cable length
1188-438: A whole range of underlying products. The members of the exchange hold positions in these contracts with the exchange, who acts as central counterparty . When one party goes long (buys a futures contract), another goes short (sells). When a new contract is introduced, the total position in the contract is zero. Therefore, the sum of all the long positions must be equal to the sum of all the short positions. In other words, risk
1254-737: Is available for Microsoft Windows , FreeBSD , Linux , Apple Mac OS 8.6 through macOS 14 Sonoma and NetBSD . In Windows XP, a degradation in performance of 1394 devices may have occurred with installation of Service Pack 2. This was resolved in Hotfix 885222 and in SP3 . Some FireWire hardware manufacturers also provide custom device drivers that replace the Microsoft OHCI host adapter driver stack, enabling S800-capable devices to run at full 800 Mbit/s transfer rates on older versions of Windows (XP SP2 w/o Hotfix 885222) and Windows Vista. At
1320-402: Is backwards compatible with the slower rates and 6-conductor alpha connectors of FireWire 400. However, while the IEEE 1394a and IEEE 1394b standards are compatible, FireWire 800's connector, referred to as a beta connector, is different from FireWire 400's alpha connectors, making legacy cables incompatible. A bilingual cable allows the connection of older devices to the newer port. In 2003, Apple
1386-443: Is designed to support plug and play and hot swapping . The copper cable it uses in its most common implementation can be up to 4.5 metres (15 ft) long and is more flexible than most parallel SCSI cables. In its six-conductor or nine-conductor variations, it can supply up to 45 watts of power per port at up to 30 volts, allowing moderate-consumption devices to operate without a separate power supply. FireWire devices implement

#17327584389281452-538: Is limited to 4.5 metres (14.8 ft), although up to 16 cables can be daisy chained using active repeaters, e.g. external hubs or the internal hubs that are often present in FireWire equipment. The S400 standard limits any configuration's maximum cable length to 72 metres (236 ft). The 6-conductor connector is commonly found on desktop computers and can supply the connected device with power. The 6-conductor powered connector, now referred to as an alpha connector, adds power output to support external devices. Typically
1518-418: Is said to require use of 261 issued international patents held by ten corporations. Use of these patents requires licensing; use without license generally constitutes patent infringement . Companies holding IEEE 1394 IP formed a patent pool with MPEG LA, LLC as the license administrator, to whom they licensed patents. MPEG LA sublicenses these patents to providers of equipment implementing IEEE 1394. Under
1584-494: Is the library source for all 1394 documentation and standards available. FireWire can connect up to 63 peripherals in a tree or daisy-chain topology (as opposed to Parallel SCSI's electrical bus topology). It allows peer-to-peer device communication — such as communication between a scanner and a printer — to take place without using system memory or the CPU . FireWire also supports multiple host controllers per bus. It
1650-436: Is transferred from one party to another is a type of a zero sum game . The total notional amount of all the outstanding positions at the end of June 2004 stood at $ 53 trillion (source: Bank for International Settlements (BIS): [1] ). That figure grew to $ 81 trillion by the end of March 2008 (source: BIS [2] ) Tailor-made derivatives, not traded on a futures exchange are traded on over-the-counter markets , also known as
1716-416: Is transferred one bit at a time. Parallel buses utilize a number of different physical connections, and as such are usually more costly and typically heavier. IEEE 1394 fully supports both isochronous and asynchronous applications. Apple intended FireWire to be a serial replacement for the parallel SCSI bus, while providing connectivity for digital audio and video equipment. Apple's development began in

Participants in a derivative market can be segregated into four sets based on their trading motives. Futures exchanges, such as Euronext.liffe and the Chicago Mercantile Exchange , trade in standardized derivative contracts. These are options contracts , swaps contracts and futures contracts on
1848-575: The CME SPAN software that is used around the world as the official performance bond (margin) mechanism of 50 registered exchanges, clearing organizations, service bureaus, and regulatory agencies throughout the world. Trading is conducted in two methods; an open outcry format and the CME Globex electronic system. More than 90 percent of total volume at the exchange occurs electronically on CME Globex. Operating during regular trading hours (RTH),
1914-663: The New York Mercantile Exchange (NYMEX) and COMEX. CME, CBOT, NYMEX , and COMEX are now markets owned by CME Group. After the merger, the value of the CME quadrupled in a two-year span, with a market cap of over $ 25 billion. Today, CME is the largest options and futures contracts open interest (number of contracts outstanding) exchange of any futures exchange in the world. The Merc trades several types of financial instruments : interest rates , equities , currencies , and commodities . CME also pioneered
1980-402: The financial crisis of 2007–2008 . Credit default swaps (CDSs), financial instruments traded on the over the counter derivatives markets, and mortgage-backed securities (MBSs), a type of securitized debt were notable contributors. The leveraged operations are said to have generated an "irrational appeal" for risk taking, and the lack of clearing obligations also appeared as very damaging for
2046-407: The open outcry method consists of floor traders standing in a trading pit to call out orders, prices, and quantities of a particular commodity or its derivatives. Different colored jackets are worn by the traders to indicate what firm they are a part of. In addition, complex hand signals (called Arb ) are used. These hand signals were first used in the 1970s. Today, however, headsets are also used by

2112-893: The 1394 Trade Association announced that products would be available before the end of 2008 using the S1600 and S3200 modes that, for the most part, had already been defined in 1394b and were further clarified in IEEE Std. 1394–2008. The 1.572864 Gbit/s and 3.145728 Gbit/s devices use the same 9-conductor beta connectors as the existing FireWire 800 and are fully compatible with existing S400 and S800 devices. It competes with USB 3.0 . S1600 (Symwave ) and S3200 (Dap Technology ) development units have been made, however because of FPGA technology DapTechnology targeted S1600 implementations first with S3200 not becoming commercially available until 2012. Steve Jobs declared FireWire dead in 2008. As of 2012 , there were few S1600 devices released, with

It launched its first weather products in 1999. Products include, but are not limited to: futures on rainfall, snowfall, hurricanes, and temperature. Derivatives market The market can be divided into two, that for exchange-traded derivatives and that for over-the-counter derivatives . The legal nature of these products
2310-531: The FCC issued an order that permitted set-top boxes to include IP-based interfaces in place of FireWire. While both technologies provide similar end results, there are fundamental differences between USB and FireWire. USB requires the presence of a host controller, typically a PC, which connects point to point with the USB device. This allows for simpler (and lower-cost) peripherals, at the cost of lowered functionality of
2376-524: The IEEE P1394 Working Group, largely driven by contributions from Sony (102 patents), Apple (58 patents), Panasonic (46 patents), and Philips (43 patents), in addition to contributions made by engineers from LG Electronics , Toshiba , Hitachi , Canon , INMOS /SGS Thomson (now STMicroelectronics ), and Texas Instruments .

At least one formerly licensed patent is known to have been removed from the pool, and other hardware patents exist that reference IEEE 1394. The 1394 High Performance Serial Bus Trade Association (the 1394 TA ) was formed to aid the marketing of IEEE 1394. Its bylaws prohibit dealing with intellectual property issues. The 1394 Trade Association operates on an individual no cost membership basis to further enhancements to 1394 standards. The Trade Association also

2772-503: The bus network, whereas, until USB 3.0, USB featured only one. This means that FireWire can have communication in both directions at the same time (full-duplex), whereas USB communication prior to 3.0 can only occur in one direction at any one time (half-duplex). While USB 2.0 expanded into the fully backwards-compatible USB 3.0 and 3.1 (using the same main connector type), FireWire used a different connector between 400 and 800 implementations. IDB-1394 Customer Convenience Port (CCP)
2838-520: The bus. Intelligent hubs are required to connect multiple USB devices to a single USB host controller. By contrast, FireWire is essentially a peer-to-peer network (where any device may serve as the host or client), allowing multiple devices to be connected on one bus. The FireWire host interface supports DMA and memory-mapped devices, allowing data transfers to happen without loading the host CPU with interrupts and buffer-copy operations. Additionally, FireWire features two data buses for each segment of
2904-445: The cables, while 1394b added a data encoding scheme called 8b/10b referred to as beta mode . Beta mode is based on 8b/10b (from Gigabit Ethernet , also used for many other protocols). 8b/10b encoding involves expanding an 8-bit data word into 10 bits, with the extra bits after the 5th and 8th data bits. The partitioned data is sent through a Running Disparity calculator function. The Running Disparity calculator attempts to keep
2970-420: The coding scheme is to support the arbitration for bus access and general bus control. This is possible due to the surplus symbols afforded by the 8b/10b expansion. (While 8-bit symbols can encode a maximum of 256 values, 10-bit symbols permit the encoding of up to 1024.) Symbols invalid for the current state of the receiving PHY indicate data errors. IEEE 1394c-2006 was published on June 8, 2007. It provided
3036-458: The devices. FireWire is capable of both asynchronous and isochronous transfer methods at once. Isochronous data transfers are transfers for devices that require continuous, guaranteed bandwidth. In an aircraft, for instance, isochronous devices include control of the rudder , mouse operations and data from pressure sensors outside the aircraft. All these elements require constant, uninterrupted bandwidth. To support both elements, FireWire dedicates
3102-563: The end of June 2004 stood at $ 220 trillion (source: BIS: [3] ). By the end of 2007 this figure had risen to $ 596 trillion and in 2009 it stood at $ 615 trillion (source: BIS: [4] ) OTC Markets are generally separated into two key segments: the customer market and the interdealer market. Customers almost exclusively trade through dealers because of the high search and transaction costs. Dealers are large institutions that arrange transactions for their customers, utilizing their specialized knowledge, expertise, and access to capital. In order to hedge

In 2007, IEEE 1394 was a composite of four documents: the original IEEE Std. 1394–1995, the IEEE Std. 1394a-2000 amendment, the IEEE Std. 1394b-2002 amendment, and the IEEE Std. 1394c-2006 amendment. On June 12, 2008, all these amendments as well as errata and some technical updates were incorporated into a superseding standard, IEEE Std. 1394–2008. Apple first included onboard FireWire in some of its 1999 Macintosh models (though it had been

Traders connect to CME Globex via Market Data Protocol (MDP) and iLink 2.0 for order routing. On October 17, 2006, Chicago Mercantile Exchange announced a merger with the Chicago Board of Trade in an $ 8 billion deal. Shareholders of both companies approved
3564-472: The merger on July 9, 2007, and the deal closed on July 12, 2007. The overarching holding company then launched as CME Group. On January 13, 2008, electronic trading at the Chicago Board of Trade shifted onto CME Globex. In 1984, the CME was investigated by the U.S. Government Accountability Office. During this investigation, it was realized that the open-outcry system could be abused. The GAO noted that

The order in which the self-IDs are assigned is equivalent to traversing the tree depth-first , post-order. FireWire is capable of safely operating critical systems due to the way multiple devices interact with the bus and how the bus allocates bandwidth to
3696-459: The number of 1s transmitted equal to 0s, thereby assuring a DC-balanced signal. Then, the different partitions are sent through a 5b/6b encoder for the 5-bit partition and a 3b/4b encoder for the 3-bit partition. This gives the packet the ability to have at least two 1s, ensuring synchronization of the PLL at the receiving end to the correct bit boundaries for reliable transfer. An additional function of
