The FOREX Lexicon

As in any worthwhile endeavor, each industry tends to create its own unique terminology. The FOREX market is no different. You, the novice trader, must thoroughly comprehend certain terms before making your first trade. As your eighth-grade English teacher taught you in vocabulary class—to use them is to know them.

Currency Pairs

Every FOREX trade involves the simultaneous buying of one currency and the selling of another currency. These two currencies are always referred to as the currency pair in a trade.

Major and Minor Currencies

The seven most frequently traded currencies (USD, EUR, JPY, GBP, CHF, CAD, and AUD) are called the major currencies. All other currencies are referred to as minor currencies. The most frequently traded minors are the New Zealand Dollar (NZD), the South African Rand (ZAR), and the Singapore Dollar (SGD). After that, the frequency is difficult to ascertain because of perpetually.

Cross Currency

A cross currency is any pair in which neither currency is the U.S. Dollar. These pairs may exhibit erratic price behavior since the trader has, in effect, initiated two USD trades. For example, initiating a long (buy) EUR/GBP trade is equivalent to buying a EUR/USD currency pair and selling a GBP/USD. Cross currency pairs frequently carry a higher transaction cost. The three most frequently traded cross rates are EUR/JPY, GBP/EUR, and GBP/JPY.

Exotic Currency

An exotic is a currency pair in which one currency is the USD and the other is a currency from a smaller country such as the Polish Zloty. There are approximately 25 exotics that can be traded by the retail FOREX participant. Liquidity—the ability to buy and sell without substantial pip spread increases; a willing buyer or seller is always available at or near the last price—is not good. Whereas a EUR/USD pair may be traded at two pips at almost any time, the EURTRY may balloon to 30 pips or more during the Asian session. changing trade agreements in the international arena.

Base Currency

The base currency is the first currency in any currency pair. It shows how much the base currency is worth as measured against the second currency. For example, if the USD/CHF rate equals 1.6215, then one USD is worth CHF 1.6215. In the FOREX markets, the U.S. Dollar is normally considered the base currency for quotes, meaning that quotes are expressed as a unit of $1 USD per the other currency quoted in the pair. The exceptions are: the British Pound, the Euro, and the Australian Dollar. If you go long the EUR/USD, you are buying the EUR.

Quote Currency

The quote currency is the second currency in any currency pair. This is frequently called the pip currency and any unrealized profit or loss is expressed in this currency. If you go short the EUR/USD, you are buying the USD.

Pips

A pip is the smallest unit of price for any foreign currency. Nearly all currency pairs consist of five significant digits and most pairs have the decimal point immediately after the first digit, that is, EUR/USD equals 1.2812. In this instance, a single pip equals the smallest change in the fourth decimal place, that is, 0.0001. Therefore, if the quote currency in any pair is USD, then one pip always equals 1⁄100 of a cent.

One notable exception is the USD/JPY pair where a pip equals $0.01 (one U.S. Dollar equals approximately 107.19 Japanese Yen). Pips are sometimes called points.

Ticks

Just as a pip is the smallest price movement (the y-axis), a tick is the smallest interval of time (the x-axis) that occurs between two trades. When trading the most active currency pairs (such as EUR/USD or USD/JPY) during peak trading periods, multiple ticks may (and will) occur within the span of one second. When trading a low-activity minor cross pair (such as the Mexican Peso and the Singapore Dollar), a tick may only occur once every two or three hours.

Ticks, therefore, do not occur at uniform intervals of time. Fortunately, most historical data vendors will group sequences of streaming data and calculate the open, high, low, and close over regular time intervals (1-minute, 5- minute, 30-minute, 1-hour, daily, and so forth). See Figure 5.1. Pips are a function of price; ticks are a function of time. Any location on a chart is effectively a Cartesian coordinate of Price, read vertically from bottom to top and Time, read horizontally from left to right.
