Basic forex terminology

Before you start trading forex, it’s important to familiarise yourself with the basic forex terminology. There is plenty to learn, but below is a quick look at some of the most common terms used by traders. Please see our Glossary for further terminology

Currency pair → forex is traded in currency pairs: one currency is bought, the other is sold. Together they make up the exchange rate.

Exchange rate → the rate of which one country’s currency can be exchanged for another currency

Base currency → the currency that comes first in the currency pair (e.g. in GBPUSD the GBP is the base currency)

Quote currency → the second currency quoted in a currency pair (e.g. in GBPUSD the quote currency is USD)

Long position (buy) → a long position refers to the purchase of an asset, with the expectation that its market value is set to rise

Short position (sell) → a short position refers to the sale of an asset, with the expectation that its market value is set to fall

Bid price → the market price for the sale of an asset

Ask price → the market price for purchasing an asset

Spread → the difference between the “bid” and “ask” prices (the selling price and the purchase price).

Appreciation → an increase in the value of an exchange rate

Depreciation/devaluation → a decrease in the value of an exchange rate

Pips → a pip stands for “percentage in point”, and is the smallest price movement any exchange rate can make. It measures the amount of change in the exchange rate for a currency pair in the forex market. A pip is the fourth and final number after the decimal point (with the exception of Japanese yen-based currency pairs, which are displayed to only two decimal points). Pips are the means by which market profits and losses are quantified

Lot → forex is traded in lots. A standard lot is equivalent to 100,000 units of the base currency. This is $100,000 if you were trading in US dollars. A mini lot has 10,000 and a micro lot has 1,000 units.

Leverage → Leverage is a way for an investor to increase their trading power and manage a greater position on the market with a nominal investment. An online broker may offer leveraged trading for up to 30 times the value of a trader’s initial investment.

Margin → the minimum deposit needed to maintain an open position (e.g. with an open position of $150,000 and leverage of 30, the required margin is $5,000).

Risk management → involves the use of strategies in order to help control or reduce financial risk. An example is a stop-loss order which is used to potentially minimise losses on a trade.

Stop loss → a stop loss order is a risk management tool allowing a position to be closed, once it reaches a specific pre-set price. This can protect against further losses on an open position if prices continue in an unfavourable direction for the investor. Please note, that placing a normal stop loss order does not guarantee you will be filled at that particular market price due to slippage.

Take profit → a take profit order is a risk management tool allowing a position to be closed automatically, once it reaches a specific pre-set profit goal. This can protect against profits being lost in an unanticipated reversal of price direction before the investor can close the position.

Profit/Loss → the proceeds of a trade, which are from realised (closed) trade positions.
