Back-Testing –
A strategy is tested or optimized on historical data and then the strategy is applied to new data to see if the results are consistent.

Bar Average -
The Bar Average can be used in the evaluation of technical analyses. The Bar Average is the (High - Low - Close)/3.

Bar Charts -
Bar Charts are constructed of the Opening, Highest, Lowest, and Closing price that occurred during the Time Interval of the bar.

For Example, on a 30-Minute Bar Chart:

Bid –
An expression indicating a desire to buy a commodity at a given price, opposite of ask.

Bid and Ask Prices –
Highest price and lowest price that an investor will pay for a tradable.

Black Box –
A proprietary, computerized trading system whose rules are not disclosed or readily accessible.

Bonds –
A long-term debt security with a stated interest rate and fixed due dates, issued by a corporation or a government, when interest and principal must be paid. There are many variations.

Broker –
A company or individual that executes futures and options orders on behalf of financial and commercial institutions and/or the general public.

To Top

 

Calendar Spread –
The purchase of one delivery month of a given futures contract and simultaneous sale of another delivery month of the same commodity on the same exchange. The purchase of either a call or put option and the simultaneous sale of the same type of option with typically the same strike price but with a different expiration month. Also referred to as a horizontal spread.

Call Option –
An option that gives the buyer the right, but not the obligation, to purchase (go "long") the underlying futures contract at the strike price on or before the expiration date.

Canceling Order –
An order that deletes a customer's previous order.

Candlestick Charts -
Candlestick charts are based on a Japanese charting method. Candlestick charts use the same data points as bar charts for each time interval. The difference lies in the way the data is represented.

The thick part of the Candlestick line is called the real body. It represents the range between that bar's opening price and closing price. An Up Candlestick occurs when the close is higher than the open; a Down Candlestick occurs when the close is lower than the open.

The thin lines above and/or below the real body are the shadows. These shadows represent the bar's price extremes. The peak of the upper shadow is the high of the bar and the bottom of the lower shadow is the low of the bar.

The real body is the essential price movement. The shadows are usually considered as extraneous price fluctuations. For additional information see Available Candlestick Formations.

Cash Commodity –
An actual physical commodity someone is buying or selling; e.g., wheat, gold, treasury bonds, etc.

Cash Contract –
A sales agreement for either immediate or future delivery of the actual product.

Charting –
The use of charts to analyze market behavior and anticipate future price movements. Those who use charting as a trading method plot such factors as high, low, and settlement prices, average price movements, volume, and open interest. Two basic price charts are bar charts and point-and-figure charts. Anticipating future price movement using historical prices, trading volume, open interest and other trading data to study price patterns.

Close -
The Daily Close is the official daily settlement from the exchange. The exchange clearinghouse determines a firm's net gains or losses, margin requirements, and the next day's price limits, based on each futures and options contract settlement price. If there is a closing range of prices, the settlement price is determined by averaging those prices. Also referred to as settle price.

The Bar Close is the last price trade at the end of each time interval.

Closed Trades –
Positions that have been either liquidated or offset.

Closing Range –
A range of prices at which buy and sell transactions took place during the market close.

Commission Fee –
A fee charged by a broker for executing a transaction. Also referred to as brokerage fee.

Continuation Charts -
Continuation Charts contain data for more than one contract. They follow the current lead contract through expiration, then follow the new lead contract.

Contract Month –
A specific month in which delivery may take place under the terms of a futures contract.

Contract Specific Charts -
Contract Specific Charts contain data for only one contract. They display price data for just the specified contract through expiration.

CQG API -
CQG’s Open API is an Application Programming Interface, which enables exporting CQG market data and analytics to external applications. It is a COM in-proc server, which provides object-oriented programming model usable from various programming languages.

CQG Symbols -
Each future or option contract, as well as each stock issue on the system, has a unique symbol. The foundation of these unique symbols is displayed in the CQG Symbols List.
CQG has established these symbols to represent each issue traded at the various international exchanges. When possible CQG symbols correspond to those used by the individual exchanges. However, exchange symbols may conflict with symbols and data formats used by other exchanges. When this occurs, alternative CQG symbols are used.

Crush Spread –
The purchase of soybean futures and the simultaneous sale of soybean oil and meal futures.

Customer Margin –
Within the futures industry, financial guarantees required of both buyers and sellers of futures contracts and sellers of options contracts to ensure fulfilling of contract obligations. FCMs are responsible for overseeing customer margin accounts. Margins are determined on the basis of market risk and contract value. Also referred to as performance-bond margin. Financial safeguards to ensure that clearing members (usually companies or corporations) perform on their customers' open futures and options contracts. Clearing margins are distinct from customer margins that individual buyers and sellers of futures and options contracts are required to deposit with brokers.

The price at which the futures contract underlying a call or put option can be purchased (if a call) or sold (if a put). Also referred to as strike price.

Expiration Date –
Options on futures generally expire on a specific date during the month preceding the futures contract delivery month. For example, an option on a March futures contract expires in February but is referred to as a March option because its exercise would result in a March futures contract position.

Extrinsic Value –
The amount of money option buyer are willing to pay for an option in the anticipation that, over time, a change in the underlying futures price will cause the option to increase in value. In general, an option premium is the sum of time value and intrinsic value. Any amount by which an option premium exceeds the option's intrinsic value can be considered time value. Also referred to as time value.

An individual or company owning or planning to own a cash commodity, corn, soybeans, wheat, U.S. Treasury bonds, notes, bills etc. and concerned that the cost of the commodity may change before either buying or selling it in the cash market. A hedger achieves protection against changing cash prices by purchasing (selling)futures contracts of the same or similar commodity and later offsetting that position by selling (purchasing) futures contracts of the same quantity and type as the initial transaction.

Hedging –
The practice of offsetting the price risk inherent in any cash market position by taking an equal but opposite position in the futures market. Hedgers use the futures markets to protect their business from adverse price changes. Selling (Short) Hedge - Selling futures contracts to protect against possible declining prices of commodities that will be sold in the future. At the time the cash commodities are sold, the open futures position is closed by purchasing an equal number and type of futures contracts as those that were initially sold. and Purchasing (Long) Hedge - Buyer futures contracts to protect against a possible price increase of cash commodities that will e purchased in the future.

Limit Order –
An order in which the customer sets a limit on the price and/or time of execution.

Limits –
The maximum number of speculative futures contracts one can hold as determined by the Commodity Futures Trading Commission and/or the exchange upon which the contract is traded. Also referred to as trading limit. The maximum advance or decline from the previous day's settlement permitted for a contract in one trading session by the rules of the exchange.

Line Charts –
Line Charts are created by connecting a specified price for each time interval displayed. A typical line chart would display a line that connects the closing price for each time interval.

Liquidate –
Selling (or purchasing) futures contracts of the same delivery month purchased (or sold) during an earlier transaction or making (or taking) delivery of the cash commodity represented by the futures contract. Taking a second futures or options position opposite to the initial or opening position.

Lognormal Distributions of Price -
If prices were "normally" distributed, future prices from the current price would be distributed in the shape of the familiar "bell curve". However, because market prices can never go negative, the distribution curve for future prices is said to be lognormal.

Long –
One who has bought futures contracts or owns a cash commodity.

Low –
The Daily Low is the lowest price traded during the trading day. It normally reflects the lowest price that occurred during all trading sessions for the day.

The Bar Low is the lowest price received during each time interval.

To Top

Maintenance –
A set minimum margin (per outstanding futures contract) that a customer must maintain in his margin account.

Margin –
Financial safeguards to ensure that clearing members (usually companies or corporations) perform on their customers' open futures and options contracts. Clearing margins are distinct from customer margins that individual buyers and sellers of futures and options contracts are required to deposit with brokers. Within the futures industry, financial guarantees required of both buyers and sellers of futures contracts and sellers of options contracts to ensure fulfilling of contract obligations. FCMs are responsible for overseeing customer margin accounts. Margins are determined on the basis of market risk and contract value. Also referred to as performance-bond margin.

Margin Call –
A call from a clearinghouse to a clearing member, or from a brokerage firm to a customer, to bring margin deposits up to a required minimum level.

Market Order –
An order to buy or sell a futures contract of a given delivery month to be filled at the best possible price and as soon as possible.

Market Profile -
Market Profile Charts use alphabetical characters to plot the price activity that occurs during each 30-minute time interval (default).

The Market Profile assigns successive letters to each 30-minute time interval. The assigned letter is plotted on the Market Profile chart at each price traded during the 30-minute period. The resulting price distribution, and distributions for other trading days can be analyzed to determine market strength and weakness. For additional information, see the Market Profile Window in the Tutorial Advisor.

Midpoint -
The midpoint of a bar can be used in the evaluation of technical analysis studies. The midpoint is the { (High - Low) / 2 }.

Month Codes
The following codes are used to identify the individual contract months, cash, and spot contracts that are available on the system:

F January N July C Cash
G February Q August X Spot
H March U September ? Lead Month
J April V October ?1 Next Month
K May X November ?2 Second Month, etc.
M June Z December

Ex: USZ06 indicates -

US = U.S. Treasury Bond (Chicago Board of Trade), Z = December, and 06 = 2006

Ex: US? indicates -

US = U.S. Treasury Bond (Chicago Board of Trade), ? = Lead Month Contract

Using the ? with a symbol eliminates the need to update chart and quote setups each time a contract expires. The system automatically displays the lead contract.

Monthly Charts
The term monthly is used to describe charts that are constructed of monthly bars.

Each monthly bar contains the Open, High, Low, and Close that occurred during each trading day.

Moving-Average Charts –
A statistical price analysis method of recognizing different price trends. A moving average is calculated by adding the prices for a predetermined number of days and then dividing by the number of days.
To Top

Non-timed bars –
Refer to bar data where the temporal aspect is not the primary determinant for creating individual bars. Unlike traditional time-based bar charts, constructed based on fixed time intervals, non-timed bars are generated using other criteria such as price range, constant volumes, trade flow, etc. The following requests are considered non-timed: CQGConstantVolumeBarsRequestCQGRangeBarsRequestCQGRenkoBarsRequestCQGTFlowBarsRequest, and all non-timed study operators available via CQGAdvancedStudyRequestCQGCustomStudyRequest, and CQGExpressionRequest.

Number of Iterations -
The number of times a calculation is performed. Generally, increasing the number of iterations improves the accuracy of a model but increasing the iterations also tends to make the total calculation slower.

Offset –
Taking a second futures or options position opposite to the initial or opening position. Selling (or purchasing) futures contracts of the same delivery month purchased (or sold) during an earlier transaction or making (or taking) delivery of the cash commodity represented by the futures contract.

Open -
The Daily Open is the first price received at the beginning of the first trading session of the trading day.
The Bar Open is the first price received at the beginning of each Time Interval.

Open Interest –
The total number of futures or options contracts of a given commodity that have not yet been offset by an opposite futures or option transaction nor fulfilled by delivery of the commodity or option exercise. Each open transaction has a buyer and a seller, but for calculation of open interest, only one side of the contract is counted.

Option –
A contract that conveys the right, but not the obligation, to buy or sell a particular item at a certain price for a limited time. Only the seller of the option is obligated to perform.

Optional Services -
Optional Services are those services that are available beyond the basic services or system enablements. They include supplemental CQG features and third party services such as news and market commentaries.

Contact your local CQG Sales representative for an explanation of the currently available Optional Services.

Option Class -
All options of the same type, i.e. all calls or all puts, on the same underlying instrument with the same expiration date.

Option Premium –
The price of an option the sum of money that the option buyer pays and the option seller receives for the rights granted by the option.

Option Spread –
The simultaneous purchase and sale of one or more options contracts, futures, and/or cash positions.

Option Type -
The designation of an option as either a call or a put.

Out-Of-The-Money Strike -
A strike that has currently has no intrinsic value. For calls, that would include strikes greater the than the current value of the underlying instrument. For puts, it would include all strikes less than the current value of the underlying.


To Top

Period -
Period usually refers to the number of bars used in the calculation of technical analysis studies.

Pit –
The area on the trading floor where futures and options on futures contracts are bought and sold. Pits are usually raised octagonal platforms with steps descending on the inside that permit buyers and sellers of contracts to see each other.

Point & Figure Charts –
These charts display price activity by plotting a column of X's on the chart at each price traded until a specified reversal amount occurs.

At the reversal price, the Point & Figure chart shifts to the left and begins plotting a column of O's on the chart at each price traded until a specified reversal amount occurs.

The process of alternately plotting X's and O's continues until the reversal amount is reached in each direction.

The resulting formation of X and O columns can be analyzed to determine market strength and weakness.

Portfolio -
Portfolios contain the issues to which conditions are applied. A portfolio can be an individual issue or a list of specific issues.

Position –
A market commitment. A buyer of a futures contract is said to have a long position and, conversely, a seller of futures contracts is said to have a short position.

Prices -
The following Prices can be used in Formulas and Technical Analyses:

Each quarterly bar contains the Open, High, Low, and Close that occurred during each quarter.

Quarterly charts are also available on selected government and industry reports. These reports may contain only one value for each quarter.

Put Option –
An option that gives the option buyer the right but not the obligation to sell (go "short") the underlying futures contract at the strike price on or before the expiration date.
To Top

Range / True Range -
The Range is the distance the market moves from the current high to the current low.

The True Range is the greatest distance of:

Retransmission -
CQG retransmits past market data each evening. The retransmitted data is used to construct the charts on the CQG system. By retransmitting the data, each user is assured of receiving updated and accurate information.

CQG retransmits the data in the form of 5-minute, 30-minute, 60-minute, Daily, Weekly, and Monthly bars. The type and quantity of the retransmitted data varies from contract to contract. The more active contracts typically receive the most transmitted data.

The Time & Sales data files are relatively large since they contain each trade for each contract on the system. For this reason, the amount of Time & Sales data that is available at any given time may be limited to several days.

The duration of the charts that are constructed from Time & Sales data (1-9 Minute Bars) is limited by the amount of Time & Sales data available in the system. For example: With two days of Time & Sales data in the system, a 1-minute chart can display enough bar data to scroll through several screens; whereas a 9-minute chart may display only 1/9th of the number of bars.

Scalper –
A trader who trades for small, short-term profits during the course of a trading session, rarely carrying a position overnight.

Signals
A Signal can be an individual condition or it can be a combination of Conditions, Bar Values, Study Operators, Mathematical Operators, and Boolean Operators.

Short –
One who has sold futures contracts or plans to purchase a cash commodity. (verb) Selling futures contracts or initiating a cash forward contract sale without offsetting a particular market position.

Speculator –
A market participant who tries to profit from buying and selling futures and options contracts by anticipating future price movements. Speculators assume market price risk and add liquidity and capital to the futures markets.

Spreading –
The simultaneous buying and selling of two related markets in the expectation that a profit will be made when the position is offset. Examples include: buying one futures contract and selling another futures contract of the same commodity but different delivery month; buying and selling the same delivery month of the same commodity on different futures exchanges; buying a given delivery month of one futures market and selling the same delivery month of a different, but related, futures market.

Stock Index –
An indicator used to measure and report value changes in a selected group of stocks. How a particular stock index tracks the market depends on its composition the sampling of stocks, the weighing of individual stocks, and the method of averaging used to establish an index.

Stop Order –
An order to buy or sell when the market reaches a specified point. A stop order to buy becomes a market order when the futures contract trades (or is bid) at or above the stop price. A stop order to sell becomes a market order when the futures contract trades (or is offered) at or below the stop price.

Stop-Limit Order –
A variation of a stop order in which a trade must be executed at the exact price or better. If the order cannot be executed, it is held until the stated price or better is reached again.

Strike Price –
The price at which the futures contract underlying a call or put option can be purchased (if a call) or sold (if a put). Also referred to as exercise price.
To Top

Technical Analysis –
Anticipating future price movement using historical prices, trading volume, open interest and other trading data to study price patterns.

Theoretical Value -
The value of an option according to a mathematical model.

Tick –
The smallest allowable increment of price movement for a contract.

Time Interval Codes -
A Time Interval Code can be appended to a contract symbol to display a specific time interval.

,5 5-minute
,60 60-minute
,xx xx-minute (where xx=1 to 120 minutes
,D Daily (Contract Specific Chart)
,DC Daily (Continuation Chart)
,W Weekly (Continuation Chart)
,M Monthly (Continuation Chart)
,Q Quarterly (Continuation Chart)
,S Semi-Annual (Continuation Chart)
,A Annual (Yearly) (Continuation Chart)
,Y Yearly (Annual) (Continuation Chart)

Example: USZ99,D indicates -
US = U.S. Treasury Bond (Chicago Board of Trade),
Z = December
99 = 1999 and
D = Daily Chart

A time interval code can be entered without specifying a symbol. When this occurs, the system defaults to the currently displayed symbol.

Examples:

For intervals greater than daily, entering the time interval code twice designates a contract-specific chart instead of a continuation chart.
Examples:

Time Limit Order –
A customer order that designates the time during which it can be executed.

Time Value –
The amount of money option buyer are willing to pay for an option in the anticipation that, over time, a change in the underlying futures price will cause the option to increase in value. In general, an option premium is the sum of time value and intrinsic value. Any amount by which an option premium exceeds the option's intrinsic value can be considered time value. Also referred to as extrinsic value.

Time and Sales Ticker –
System consisting of an online graphic service that transmits price and time information throughout the day.

Time-Stamped –
Part of the order-routing process in which the time of day is stamped on an order. An order is time-stamped when it is (1) received on the trading floor, and (2) completed.

Time Until Expiration -
The time remaining until an option expires. Measured in days or years.

Trading Day -
Most securities and commodities trade for a single session, lasting several hours each day, while others are traded during multiple sessions lasting many hours. Exchange trading systems, such as GLOBEX from the CME, offer around-the-clock trading for an increasing number of contracts.

CQG displays the trading day for each market, beginning with the morning opening in each market's primary trading location or beginning with the Exchange's established opening time. For selected contracts traded through the GLOBEX system, the CME has established an opening time coinciding with the opening of the Far Eastern markets.

For example: The CME has established that the opening time for Eurodollars is 14:00 CT, (2:00 PM CT). Therefore, the CQG daily chart for Eurodollars contains data from 14:00 to 13:59 (the close of the primary session) the following "day."

Trailing Stop –
A buy trailing stop order sets the stop price at a fixed amount above the market price with an attached "trailing" amount. As the market price drops, the stop price drops by the trail amount, but if the instrument price arises, the stop loss price doesn't change, and a market order is submitted when the stop price is hit.

Treasury Bill –
A Treasury bill is a short-term U.S. government obligation with an original maturity of one year or less. Unlike a bond or note, a bill does not pay a semi-annual, fixed rate coupon. A bill is typically issued at a price below its par value and is therefore a discounted instrument. The level of the discount depends on the level of prevailing interest rates. In general, the higher short-term interest rates are, the greater the discount. The return to an investor in bills is simply the difference between the issue price and par value.

Treasury Bond –
Government-debt security with a coupon and original maturity of more than 10 years. Interest is paid semiannually.

Treasury Note –
Government-debt security with a coupon and original maturity of one to 10 years.

True Highs/Lows -
True Highs are defined as the maximum of either the current bar's high or the previous bar's close.
True Lows are defined as the minimum of either the current bar's low or the previous bar's close.
