Description

CROSS REFERENCE

This application claims the benefit of and priority from U.S. Provisional Patent application 61/452,222, entitled “Context-based Keyboard”, filed Mar. 14, 2011, the entire disclosure of which is incorporated herein by reference.

FIELD

The disclosure relates generally to keyboards and, more specifically, to virtual keyboards, which are customized based on an input context, e.g., an input context for defining a financial instrument.

BACKGROUND

A keyboard includes an arrangement of physical or virtual buttons or keys configured to receive input from a user of a computing device.
Each key of the keyboard typically represents a single written symbol or character. Some symbols may be produced in response to a user pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers, signs or characters, other keys or simultaneous key presses can produce actions or computer commands.
The keyboard may be used to enter commands on a command-line interface or a command syntax, and/or to type text and numbers into a word processor, text editor or other program.
A virtual keyboard (also known as a software keyboard or an on-screen keyboard) may be generated by a computer program that displays an image of a keyboard including a plurality of virtual keys on a screen. Another input device, such as a mouse or a touch screen may be used to operate each virtual key of the virtual keyboard.
Other graphical and/or virtual user interfaces may be used for receiving input from the user of the computing device. For example, a drop-down list is a user interface control graphical user interface (GUI) element (“widget”), similar to a list box, which allows the user to choose one value from a list. When a drop-down list is inactive, the drop-down list displays a single value. When activated, the drop-down list displays (drops down) a list of values, from which the user may select one. When the user selects a new value, the drop-down list reverts to its inactive state, displaying the selected value.
Virtual keyboards and/or interfaces have become very popular in touch screen enabled devices, for example, touch screen enabled cell phones, tablet computers and the like, due to the additional cost and space requirements of other types of hardware keyboards. Some operating systems include on-screen keyboards and/or interfaces that can be controlled with the mouse.
Relatively complex interfaces, e.g., interfaces configured for receiving a large amount of data, may be by computer applications in various fields, for example, in the field of financial instruments.
Pricing financial instruments is a complex art requiring substantial expertise and experience. Trading financial instruments, such as options, involves a sophisticated process of pricing typically performed by a trader.
The term “option” in the context of the present application is broadly defined as any financial instrument having option-like properties, e.g., any financial derivative including an option or an option-like component. This category of financial instruments may include any type of option or option-like financial instrument, relating to some underlying asset. Assets as used in this application include anything of value; tangible or non-tangible, financial or non-financial, for example, stocks; currencies; commodities, e.g., oil, metals, or sugar; weather, e.g. the temperature at a certain area; electricity; gas emission; interest rates; forward-rate agreements (FRA); swaps; futures; bonds; credit; mortgages; indices; and the like. For example, as used herein, options range from a simple Vanilla option on a single stock and up to complex convertible bonds whose convertibility depends on some key, e.g., the weather.
The term “Exchange” in the context of the present application relates to any one or more exchanges throughout the world, and includes all assets/securities, which may be traded in these exchanges. The terms “submit a price to the exchange”, “submit a quote to the exchange”, and the like generally refer to actions that a trader may perform to submit a bid and/or offer prices for trading in the exchange. The price may be transferred from the trader to the exchange, for example, by a broker, by online trading, on a special communication network, through a clearing house system, and/or using in any other desired system and/or method.
The price of an asset for immediate, e.g., 1 or 2 business days, delivery is called the spot price. For an asset sold in an option contract, the strike price is the agreed upon price at which the deal is executed if the option is exercised. For example, a stock option involves buying or selling a stock. The spot price is the current stock price on the exchange in which is the stock is traded. The strike price is the agreed upon price to buy/sell the stock if the option is exercised.
To facilitate trading of options and other financial instruments, a market maker suggests a bid price and offer price (also called ask price) for a certain option. The bid price is the price at which the market maker is willing to purchase the option and the offer price is the price at which the market maker is willing to sell the option. As a market practice, a first trader interested in a certain option may ask a second trader for a quote, e.g., without indicating whether the first trader is interested to buy or to sell the option. The second trader quotes both the bid and offer prices, not knowing whether the first trader is interested in selling or buying the option. The market maker may earn a margin by buying options at a first price and selling them at a second price, e.g., higher than the first price. The difference between the offer and bid prices is referred to as bid-offer spread.
A call option is the right to buy an asset at a certain price (“the strike”) at a certain time, e.g., on a certain date. A put option is the right to sell an asset at a strike price at a certain time, e.g., on a certain date. Every option has an expiration time in which the option ceases to exist. Prior to the option expiration time, the holder of the option may determine whether or not to exercise the option, depending on the prevailing spot price for the underlying asset. If the spot price at expiration is lower than the strike price, the holder will choose not to exercise the call option and lose only the cost of the option itself. However, if the strike is lower than the spot, the holder of the call option will exercise the right to buy the underlying asset at the strike price making a profit equal to the difference between the spot and the strike prices. The cost of the option is also referred to as the premium.
A forward rate is defined as the predetermined rate or price of an asset, at which an agreed upon future transaction will take place. The forward rate may be calculated based on a current rate of the asset, a current interest rate prevailing in the market, expected dividends (for stocks), cost of carry (for commodities), and/or other parameters depending on the underlying asset of the option.
An at-the-money forward option (ATM) is an option whose strike is equal to the forward rate of the asset. In some fields, the at-the-money forward options are generically referred to as at-the-money options, as is the common terminology in the commodities and interest rates options. The at the money equity options are actually the at the money spot, i.e. where the strike is the current spot rate or price.
An in-the-money call option is a call option whose strike is below the forward rate of the underlying asset, and an in the-money put option is a put option whose strike is above the forward rate of the underlying asset. An out-of-the-money call option is a call option whose strike is above the forward rate of the underlying asset, and an out-of-the-money put option is a put option whose strike is below the forward rate of the underlying asset.
An exotic option, in the context of this application, is a generic name referring to any type of option other than a standard Vanilla option. While certain types of exotic options have been extensively and frequently traded over the years, and are still traded today, other types of exotic options had been used in the past but are no longer in use today. Currently, the most common exotic options include “barrier” options, “digital” options, “binary” options, “partial barrier” options (also known as “window” options), “average” options, “compound” options and “quanto” options. Some exotic options can be described as a complex version of the standard (Vanilla) option. For example, barrier options are exotic options where the payoff depends on whether the underlying asset's price reaches a certain level, hereinafter referred to as “trigger”, during a certain period of time. The “pay off” of an option is defined as the cash realized by the holder of the option upon its expiration. There are generally two types of barrier options, namely, a knock-out option and a knock-in option. A knock-out option is an option that terminates if and when the spot reaches the trigger. A knock-in option comes into existence only when the underlying asset's price reaches the trigger. It is noted that the combined effect of a knock-out option with strike K and trigger B and a knock-in option with strike K and trigger B, both having the same expiration, is equivalent to a corresponding Vanilla option with strike K. Thus, knock-in options can be priced by pricing corresponding knock-out and vanilla options. Similarly, a one-touch option can be decomposed into two knock-in call options and two knock-in put options, a double no-touch option can be decomposed into two double knock-out options, and so on. It is appreciated that there are many other types of exotic options known in the art.
Certain types of options, e.g., Vanilla options, are commonly categorized as either European or American. A European option can be exercised only upon its expiration. An American option can be exercised at any time after purchase and before expiration. For example, an American Vanilla option has all the properties of the Vanilla option type described above, with the additional property that the owner can exercise the option at any time up to and including the option's expiration date. As is known in the art, the right to exercise an American option prior to expiration makes American options more expensive than corresponding European options.
Generally in this application, the term “Vanilla” refers to a European style Vanilla option. European Vanilla options are the most commonly traded options; they are typically traded over the counter (OTC). American Vanilla options are more popular in the exchanges and, in general, are more difficult to price.

Some demonstrative embodiments include a context-based virtual keyboard, which is customized based on an input context to be inputted via the virtual keyboard, as described in detail below.
Some computer-based applications may be configured to receive from a user a context (“input context”), which includes a plurality of fields, values, parameters, definitions, items and/or any other suitable input components (“context components”). The input context may be received, for example, via a suitable input syntax, command line, input line, and the like.
In some demonstrative embodiments, the input context may include a predefined combination of a plurality of context components, wherein a context component may have an input element selected from a predefined plurality of input elements.
In some demonstrative embodiments, e.g., as described below, the input context may correspond to a financial instrument, for example, the input context may include an input context defining a financial instrument, e.g., a Foreign Exchange (FX) or Exchange-rate (ER) option, options on Interest Rate (IR) futures and/or options on commodities and/or any other suitable financial instruments and/or markets. One skilled in the art may apply the embodiments to other options and/or option-like financial instruments, e.g., any suitable options on any suitable asset instruments and/or options on non-asset instruments, such as options on the weather and/or the temperature, and the like, with variation as may be necessary to adapt for factors unique to a given financial instrument.
The phrase “financial instrument” (also referred to as “trade structure”, “trade”, “deal” or “trade strategy”) may refer to any one or more suitable derivative instruments, e.g., forwards, swaps, futures, exchange options, OTC options, and the like, which derive their value from the value and characteristics of one or more underlying assets of any suitable “asset class”, e.g., FX, Interest Rate, Equity, Commodities, Credit, weather, energy, real estate, mortgages, and the like; and/or may involve more than one asset class, e.g., cross-asset, multi asset, and the like. The phrase “financial instrument” may also refer to any suitable combination of one or more financial instruments.
The phrase “defining a financial instrument” may refer to setting, determining, establishing and/or defining a plurality of parameters (“financial instrument parameters”), which construct, create, build and/or define a financial instrument, for example, in a manner, which may enable trading, pricing, handling, and/or processing the financial instrument.
It should be appreciated, that other embodiments may include or be implemented with respect to any other suitable input context. In one example, the input context may include an input context for defining any suitable item, asset, product, service, command, criterion, and/or operation according to an input from a user. In one example, the input context may include a plurality of context components defining a search criterion, which includes a combination of a predefined set of criterion parameters. For example, the context input may define a search criterion for searching a product, service or asset, e.g., a real estate asset.
For example, the context input may include a plurality of context components defining attributes of a real-estate asset. For example, a first context component may include a context component selected from a predefined plurality of input elements defining a type of the real-estate asset, e.g., an apartment, a building, a cottage, and the like; a second context component may include a context component selected from a predefined plurality of input elements defining a transaction of the real-estate asset, e.g., sale, rent, and the like; a third context component may include a context component selected from a predefined plurality of input elements defining a general location of the real-estate asset, e.g., a plurality of cities; a fourth context component may include a context component selected from a predefined plurality of input elements defining a specific location of the real-estate asset, e.g., a plurality of streets; and the like.
In some demonstrative embodiments, a user may be required to define a financial instrument, for example, in order to price the financial instrument, analyze the financial instrument, trade the financial instrument, convey the financial instrument to another user and/or entity, process the financial instrument and/or handle the financial instrument in any other suitable manner. For example, when traders want to perform a trade they must convey to their counterparty the type of trade they want to perform. Given the trade type there is a list of context components, e.g., in the form of field names and values, which need to be specified. In one example, for a deal of type “vanilla call option” a user may have to specify the following context components:
Deal type=Vanilla
Call=USD
Put=JPY
Strike=85
Expiry=3 Months
Notional=1 Million
It is noted that deals of higher complexity may have additional and/or alternative context components.
Some devices, for example, touch screen enabled devices, e.g., smartphones, touch screen enabled cell phones, tablet computers, personal-digital-assistants, and the like, may implement virtual keyboards and/or interfaces, e.g., due to the additional cost and space requirements of hardware keyboards.
Using a conventional keyboard layout for specifying the input parameters defining the financial instrument may require “wasting” a large area of the screen for graphically presenting the entire conventional keyboard layout. In addition, the user may invest efforts and time to “type” in text representing each of the input parameters.
An interface including a drop-down list for presenting the different input elements with respect to each of the input parameters defining the financial instrument may be inconvenient for the user, for example, if the user is required to scroll through a drop-down list, which includes a relatively large number of options and/or if a relatively large number of drop-down lists are presented to the user.
Some demonstrative embodiments, include a context-customized virtual keyboard, and/or methods, devices and/or systems of defining, generating and/or utilizing the context-customized virtual keyboard, e.g., as described below.
In some demonstrative embodiments, the context-customized virtual keyboard may be customized to receive from a user an input context having a combination of a predefined plurality of context components, wherein a context component is selected from a predefined plurality of input elements.
For example, the input context may include an input line or command line, e.g., in the form of an input text line, for defining a financial instrument. The context components may include the components required for defining the financial instrument and the input elements include the different available inputs for the context components. For example, a first context component may include a type of the financial instrument, and the input elements of this context component may include “Vanilla”, “RR”, and the like. A second context component may include a currency type, and the input elements of this context component may include US Dollar (“USD”), Euro (“EUR”), Japanese Yen (“JPY”), and the like. A third context component may include a time period, and the input elements of this context component may include “year”, “day”, “month”, “one year”, three months” and the like.
In some demonstrative embodiments, the context-customized virtual keyboard may include a graphical keyboard including a plurality of graphical keyboard elements representing the plurality of input elements, e.g., as described below with reference to FIGS. 2-7.
In some demonstrative embodiments, the input context may be entered by the user via the graphical keyboard elements, e.g., using a touch screen, a mouse and/or any other input device.
