Glossary of trading terms and terminology

Trading Glossary

Although Trading AtoZ tries to use language that is free of acronyms, or terms that are unusual, there may be occasions where they creep in. This trading glossary shall cover those terms with a brief description. The glossary is being constantly reviewed with additions made on a regular basis.

Table of contents


ArbitrageArbitrage is the practice of simultaneously buying and selling an asset to take advantage of a difference in price. The asset will usually be bought and sold on different exchanges, using different currencies or with different financial products, depending on how the discrepancy in the price occurs.

Ask – The ask refers to the price at which you can buy an asset or security from a seller. It can also be referred to as “asking price“, “offer” and “offer price“.

Asking Price – See ask.

Asset Class – See the Asset Types page.

ATR – See average true range.

At The MoneyAt the money is a term used in options trading when the strike price is identical to the underlying market price.

Average True Range – The average true range (ATR) is a technical analysis indicator that measures an assets volatility. It is calculated by determining the range of price (High – Low) and then averaging that over a number of trading periods.


Base Currency – The term base currency refers to the first currency quoted in a forex pair.

Base Rate – A base rate is the interest rate that a central bank, such as the Bank of England or Federal Reserve, will charge commercial banks for loans. It can also be referred to as “the bank rate” and “the base interest rate”.

Basis Point – The term refers to the smallest unit of measurement in relation to a change in a percentage or price. The most common use is for a base rate. The change in a base rate is usually referenced as a change by a number of basis points. For example, if the Bank of England increases interest rates by 0.25% it would be referenced as in increase of 25 basis points.

Bear/ Bears – A bear is a trader that believes a market or asset is heading in a downwards direction. A bear is the opposite of a bull.

Bearish – This is how bears describe their mentality. A bear is bearish because they believe a market or asset will head in a downwards trajectory.

Bear Market – A bear market is declared when the associated market has a sustained downward trajectory. For equities markets this is typically defined as a fall of more than 20% from the peak.

Bid – The bid refers to the price at which you can sell an asset or security to a buyer.

Bollinger Bands – This is an indicator used by technical analysts. They are formed using an upper band (above the price) and a lower band (below the price). By default, the bands are set at 2 standard deviations away from the current price. When volatility is low the bands will be tight and conversely when volatility is high the bands will be broad. They are often used to identify levels of support and resistance.

Bonds – See the Asset Types page.

Broker – See the Brokers page.

Bull/ Bulls – A bull is a trader that believes a market or asset is heading an an upwards direction. A bull is the opposite of a bear.

Bullish – This is how bulls describe their mentality. A bull is bullish because they believe a market or asset will head in an upwards trajectory.

Contract For Difference – A contract for difference is a type of financial derivative and are purely speculative instruments. The contract is an agreement to exchange the difference in price of an asset from when the position is opened to when it is closed.

Cost Of Carry – This term refers to how much a position will cost you while it remains open. This is above any opening and closing transaction costs, or any tax that may become payable. It often refers to overnight funding charges, interest payments on margin accounts and forex transactions. The cost of carry can be significant and will affect your overall profitability so must be included and monitored in your trading accounts.

Covered Call – A covered call is when a trader sells (writes) a call option for an asset that they currently own. For example, a trader may own 1000 shares in XYZ corporation and then sell a call option in XYZ corporation. Their shares are then protected from a fall in price as they would simultaneously profit from their call option.

Currency – See foreign exchange.


Day TradingDay trading is a short term trading strategy that involves opening and closing a trade in a single day and before the market closes.

Dead Cat Bounce – A dead cat bounce occurs when a price has a temporary recovery after an extended decline, followed by the continuation of the original downtrend. The term dead cat bounce refers to the notion that even a dead cat will bounce if it falls from a great height.

Derivative – A derivative is a financial product that derives its value from the price of an underlying asset. They are often used by traders to speculate on the future price movement of an asset, without having to buy or sell the asset itself.

Earnings Per Share – This is perhaps the most important data item a company releases. It shows how much profit a company makes for each share listed.

EBIT(DA) – There are multiple variants of this acronym. The full acronym stands for “earnings before interest, tax, depreciation and amortisation”. Sometimes you will see it referred to as just EBIT, but for this just remove the depreciation and amortisation.

ECB – The ECB is the European Central Bank. The ECB is the central bank for the Eurozone, the countries that use the Euro as their currency.

EMA – See exponential moving average.

EPS – See earnings per share.

Equities – See shares.

Expiry/Expiration DateExpiry dates apply to many financial instruments and is the date when the position automatically closes.

Exponential Moving AverageExponential moving averages (EMA) were developed to mitigate the main problem with simple moving averages. They are calculated in a way that gives each data point more weight than its predecessor. This means they react fast to a change in price action.

Fibonacci Retracement – This is a technical analysis tool used to identify price targets by adopting the fibonacci sequence. When prices retrace from a high or low they often retrace by a percentage that coincides with a number from the fibonacci sequence.

Fill – The term fill relates to the execution of an order. When an order has been completed it is referred to as filled. There is no guarantee that all orders will be filled, either in part or in full. This could happen when the conditions of the order are no longer viable. For example a share price could gap through the price and therefore can not be executed, or filled.

Filled – See fill.

Financial Instrument – A financial instrument refers to any asset that can be traded. The trading of these assets requires a buyer (the new owner of the asset) and a seller (the previous owner of the asset). See asset types for various types of financial instrument.

Futures Contract – A futures contract is a more regulated and rigid form of forward contract. A futures contract is an agreement between two parties to buy or sell an asset at a specified price on a predefined expiry date. Futures contracts are traded on an exchange, can not be customised and are not negotiable.

Fx – See foreign exchange.


GDP – See gross domestic product.

Grey Market – The grey market is used by traders who want to take a position in shares before their initial public offering (IPO). The price on the grey market is therefore a prediction of what the company will be trading at once the IPO has occurred.

Gross Domestic Product – This is the total value of all goods and services produced in a country over a specified period. The value is used to determine the size and health of an economy. The % change in gross domestic product can be used to compare countries.

Ichimoku Cloud – The Ichimoku Cloud is a technical analysis indicator that simultaneously defines support and resistance levels, momentum as well as providing trading signals. Translating from Japanese, the Ichimoku Cloud broadly means “equilibrium chart at a glance” because traders can see multiple pieces of valuable information with a single indicator.

In The MoneyIn the money is a term used in options trading. The term refers to the relationship between as assets underlying price and the options strike price. For example, if the underlying price has gone above the strike price for a call option then it is in the money. Additionally, if the underlying price has gone below the strike price for a put option it is also in the money.

Interest Rates – An interest rate is the amount a lender will charge a borrower in return for a loan. This is usually expressed as a percentage and relates to a whole year. For example, if I borrowed £1000 at an interest rate of 5%, then I could expect to pay £50 in interest over the course of the first year.

MACD – See moving average convergence divergence.

Maintenance MarginMaintenance margin is the amount of capital that needs to be available in your account to keep a leveraged position open. This extra margin ensures that you always have enough capital to fund the total value of your position including any running losses.

MarginMargin is the amount of capital required in your trading account to open a leveraged position. The amount of margin can not be used to open or maintain other positions.

Margin Call – A margin call occurs when a position has moved against you and the maintenance margin is no longer sufficient to cover your running losses. A trader can either deposit more capital to cover the increased margin, or close the position. Closing the position may still require additional deposits depending on how far the trade has moved against you.

Margin Deposit – The margin deposit is the amount of margin required in your trading account to open a position.

Market CapitalisationMarket capitalisation is the total market value of a company’s shares on the market.

Market Maker – A market maker is someone that buys and sells large quantities of a particular asset. This facilitates liquidity and ensures the market runs smoothly and efficiently. Market makers are typically large institutional banks.

Market Order – See order types page.

Micro Lot – A micro lot is a currency trade size. A micro lot is equivalent to one tenth of a mini lot. A micro lot is therefore 1000 units of a currency. If you trade a single micro lot for currency pairs based in USD a 1 pip change is worth $0.10.

Mini Lot – A mini lot is a currency trade size. A mini lot is equivalent to one tenth of a standard lot. A mini lot is therefore 10000 units of a currency. If you trade a single mini lot for currency pairs based in USD a 1 pip change is worth $1.

Monetary PolicyMonetary policy can be set by a central bank or a government. The aim of monetary policy is to control money supply to the economy. A tight monetary policy aims to slow the economy by restricting access to finance. A loose monetary policy aims to speed up the economy by increasing access to finance. This is generally achieved by adjusting interest rates, open market operations, direct lending to banks, bank reserve requirements and other unconventional emergency lending programs (such as quantitative easing).

Monetary Policy Committee – Most countries set monetary policy through a monetary policy committee. These are a group of experts independent from government that vote on monetary policy. The UK monetary policy committee is part of the Bank of England.

Moving Average – A moving average is an indicator used in technical analysis that is applied to price charts. They are calculated by finding the average close price for a specified number of trading points. For example a 10 day moving average would total the close price for the past 10 days and then divide the total by 10. The purpose of moving averages is to smooth the price making them less susceptible to short time prices. They are good method of identifying long term price trends. Unfortunately moving averages take a while to identify trends due to their averaging nature.

Moving Average Convergence DivergenceMoving average convergence divergence (MACD) is an indicator used in technical analysis. As the name suggests it is based on moving averages. The MACD is made up of four key data points, a fast (short term) moving average, a slow (long term) moving average, the difference between the fast and slow averages (known as the MACD line), a moving average of the MACD line (known as the signal).

The majority of charting packages will plot MACD with the following default values. Slow moving average of 26, fast moving average of 12, signal moving average of 9. The MACD line and the signal are both plotted as line charts. When the MACD line moves above the signal line it can be interpreted as a buy signal. When the MACD line moves below the signal line it can be interpreted as a sell signal.

A modern approach to calculate MACD is to use exponential moving averages (EMA) instead of simple moving averages. The benefit of using an EMA is to give a greater weight to more recent price changes and therefore changes in momentum are signalled earlier.


Nano Lot – A nano lot is a currency trade size. A nano lot is equivalent to one tenth of a micro lot. A nano lot is therefore 100 units of a currency. If you trade a single nano lot for currency pairs based in USD a 1 pip change is worth $0.01.

NFP – See non-farm payrolls.

Non-Farms – See non-farm payrolls.

Non-Farm Payrolls – The non-farm payrolls report is a monthly statistic released in the US. It states how many people are employed in manufacturing, construction and goods companies. They can also be known as non-farms, or NFP. This is one of the most important statistics released and as a trader you should be aware when it is due. See the Trading AtoZ economic calendar for more information.

OTC – This stands for over-the-counter, and refers to a trade that is not made on a formal exchange. Foreign exchange is the most widely recognised asset that is traded OTC.

Out Of The MoneyOut of the money is a term used in options trading when the underlying market price has yet to reach the strike price. The options contract has no intrinsic value and would therefore expire worthless.

Overexposure – When a trader is overexposed they have committed too much of their capital to a single trade, sector or asset type. Their account therefore becomes too exposed were market conditions to deteriorate.

Over The Counter – See OTC.


PipPip stands for price interest point and is used within foreign exchange to represent the last digit of the quoted price. If an exchange rate changes from 0.8714 to 0.8721 then it has increased by 7 pips.

Pipette – A pipette is a tenth of a pip. Some brokers provide foreign exchange quotes using an extra digit so they can give tighter spreads to their customers. Using the example in the pip definition, the quotes using pipettes could be 0.87143 to 0.87214.

Price To Earnings Ratio – The price to earnings ratio is derived by dividing the share price by the earning per share. The resulting ratio provides an indication of how the market values the company. A high ratio, especially compared to their peers, implies it is valued highly. Whereas a low ratio, again compared with their peers, implies it has a low valuation.

Put Option – A put option is a contract that gives the buyer the right but not the obligation to sell a specified asset at a specific price, on a specific date of expiry.


QE – See quantitative easing.

Quantitative EasingQuantitative easing (QE) is a monetary policy tool used by central banks. Central banks create electronic money and use this to purchase government or corporate bonds on a large scale. The intention is to lower interest rates and increase money supply. QE rose to prominence after the 2008 financial crash and subsequent recession.

Quote Currency – The quote currency is the second currency mentioned in a forex pair. For example, the quote currency for the forex pair GBPUSD is USD.


Rally – A rally occurs when the price of an asset shows sustained upward momentum. These typically occur after a period when the price has been flat, trading in a narrow band, or after a decline. A rally may be short lived and therefore does not always constitute a trend.

Random Walk TheoryRandom walk theory is a hypothesis where the stock market moves in an unpredictable way. Proponents of this theory believe the future price of any asset is completely independent of its own historical movement. If random walk theory is true then technical analysis can not be true.

Range – Range is the difference between the highest and lowest price of an asset in a given period. For example, if XYZ Stock traded at a high of £10.50 and a low of £10.25 then its range would be £0.25.

Rate of Return – The rate of return is the increase or decrease for an investment over a specified time period. The rate of return is expressed as a percentage of the initial cost of the investment. A positive rate of return means the position has made a profit. A negative rate of return means the position has made a loss. For example if I bought 100 XYZ shares for a total investment of £1000 and then sold them for £1100 I would have made a profit of £100. My rate of return would therefore be £100/£1000 = 10%.

Relative Strength Index – The term relative strength index (RSI) relates to an indicator used in technical analysis. It calculates the momentum of assets to determine whether they are overbought or oversold. Many technical analysts believe that an RSI level above 70 means the asset is overbought and may be reaching a high, where as an RSI level below 30 means the asset is oversold and may reaching a low.

Resistance – A resistance level is a higher price on a chart where the market has previously encountered significant difficulty in overcoming. Resistance levels are commonly used to place orders to either open or close positions.

Return on EquityReturn on equity (ROE) is a way of measuring a company’s profitability. ROE is expressed as percentage of shareholder equity. It is therefore how much income a company generates as a percentage of capital received from shareholders.

Reversal – A reversal is a point on a chart when the price of an asset changes direction. A prior trend has to be in place for a reversal to occur. For this reason they are also referred to as trend reversals.

Rights Issue – When a company offers additional shares to its existing shareholders it is called a rights issue. These additional shares are usually offered at a reduced price for a limited time period.

Risk ManagementRisk management is the process that traders follow to limit and reduce the amount of risk they have in their portfolio.

ROE – See return on equity.

Rollover – When a position reaches its expiry date you may be given the option to automatically rollover into the next contract. This process can occur for most asset types.

RSI – See relative strength index.


ScalpingScalping occurs when someone executes a scalp trade.

Scalp Trade – A scalp trade is the act of opening and then closing a position very quickly. Scalp traders attempt to make profits from small changes in price.

Scalp Trading – This is a trading technique that relies on scalping.

Sectors – A sector is equivalent to a category. They are categories of assets within markets and are useful for analysing and comparing companies with similar characteristics.

Share Buyback – A share buyback occurs when a company wants to buy back some of its share from investors. These usually occur within highly profitable companies that can not find other more productive uses for their cash reserves.

Share Repurchase – See share buyback.

Shares – A share is a unit of ownership of a company and are usually traded on a stock exchange. They are also referred to as stocks or equities.

ShortingShorting is the process of short selling.

Short Position– When traders refer to having a short position they are wanting an asset price to decrease in order to makes a profit. For example, if I short 100 shares of XYZ stock at £10 then I make a profit if the price falls below £10.

Short Selling – The process of short selling is when a trader sells an asset that they do not currently own. They want a decrease in value so they can close the trade for a profit. It is also known as shorting.

Simple Moving Average – See moving average.

SlippageSlippage occurs when an order is executed at a price that differs from the requested price. This usually occurs in fast moving markets, or where there is low liquidity.

SNBSNB is the Swiss National Bank. It is the central bank for Switzerland.

Spot Price – The term spot price refers to the current value of an underlying asset. This value is the price it can be bought or sold with the expectation of immediate delivery. The term is most commonly used in the commodities and forex markets.

Spot Rate – See spot price.

Spread BettingSpread betting is a product offered by brokers that allows leveraged trading on financial markets. When a trader uses spread betting they are placing a bet on the direction in which a market will move.

Spread – The spread refers to the difference between the buy and sell prices quoted for an asset. For example, if XYZ Stock has a bid price of £10.05 and ask price of £10.10, it would have a spread of £0.05. Assets with high liquidity tend to have tighter (small) spreads. Assets with low liquidity can have wide (large) spreads.

Standard DeviationStandard deviation is a mathematical calculation. It is used to calculate how much statistical variance there is in a data set. When applied to trading it is a useful calculation to determine volatility. Some technical analysis indicators use standard deviation as part of their formulation.

Standard Lot – A standard lot is a currency trade size. A standard lot is 100000 units of a currency. If you trade a single standard lot for currency pairs based in USD a 1 pip change is worth $10.

Straddle – A straddle is an options trading strategy. They enable traders to speculate on the volatility of an asset without needing to know the direction of price movement. A straddle trade involves a trader buying or selling simultaneous call and put options. The options must have matching strike prices and expiration dates.

Strike Price – A strike price is a predetermined fixed price at which an options contract can be exercised. It relates to the price that the underlying asset can be bought or sold.

Support – A support level is a lower price on a chart where the market has previously encountered significant difficulty in breaking below. Support levels are commonly used to place orders to either open or close positions.


Technical Analysis – See technical analysis page.

Technical Analyst – A technical analyst is someone that researches and executes their trades using technical analysis.

Theta – See time decay.

Ticker – See stock symbol.

Time DecayTime decay (theta) measures how much an options contract price decays for each day of time that passes.

Time ValueTime value is the amount by which an options contract price exceeds its intrinsic value.

Tom-next – The term Tom-next means “tomorrow-next day”. Tom-next transactions mean that traders do not have to take take physical delivery of currency while allowing them to maintain their forex positions overnight. The expected delivery day for forex transactions is two days after they were opened but tom-next can be used to extend the trade beyond this date.

Instead of a trader taking delivery of a currency, the broker swaps any overnight positions for an equivalent contract that starts the following day. The difference between these two contracts is known as the tom-next adjustment rate.

If you are buying a currency with a higher interest rate, then you would receive an interest payment. If you are buying a currency with a lower interest rate, then you would have to pay interest. This payment is known as the cost of carry.
