When you view a forex quote like EUR/USD at 1.08456, you should know that the numbers that appear after the decimal point are extremely important and aren't just random numbers. They are actually the precision markers that can either help your trading account or hurt it. Each decimal point signifies a unit price movement, and understanding what they mean will be the determining factor of whether you're able to trade profitably or lose money.
In forex trading, decimals refer to the digits that appear after the decimal point in the currency pair quote. Usually, brokers will display prices in four decimal points or five decimal points, and this is by design. It exists because the forex market moves in small increments, thus needing traders to be able to see those micro-movements to make informed decisions.
Understanding the Structure of a Forex Quote
All forex quotations adhere to a consistent structure comprising paired currencies. The first currency indicates a base currency, and the second indicates a quoted currency. For example, EUR/USD = 1.08456 means 1 euro is equivalent to 1.08456 US dollars.
Looking at that number more closely, 1 is the whole dollar amount, while 08456 represents the fractional value. The fourth decimal place, in this case the 5, is typically where you might see 1 pip of movement. The fifth decimal, here the 6, would represent a fractional pip, also known as pipette.
The Relationship Between Decimals, Pips, and Pipettes
A pip, or "percentage in point," is the typical standard unit of measurement for forex price movement. For nearly all currency pairs, a pip is equivalent to the fourth decimal place, or 0.0001. For example, if EUR/USD moves from 1.0845 to 1.0846, that is one pip price change.
In forex trading, a pipette is essentially telling you one step further down to another decimal point. A pipette is one tenth of a pip, or the fifth decimal place, and the value is 0.00001. For example, if the EUR/USD has one of its prices quoted as 1.08456 moving to 1.08458, that is equal to 0.2, or two pipettes.
How Decimal Precision Impacts Trading Strategies
The decimal precision has a direct impact on the spread per trade. The difference between the ask price (where you buy) and the bid price (where you sell) defines the spread. When brokers quote prices to five decimal places, a broker may provide you a spread of 0.8 pips, which is essential versus quoting it rounded to 1 pip. After hundreds or thousands of trades, the decimal difference adds up to a significant number.
Decimal precision is essential for a scalper to enter and exit trades quickly. For example, a scalper may be targeting a profit only 2-3 pips above and below, respectively. When you are targeting small profits, the entry and exit points are extremely important. Can you imagine the difference one broker quotes EUR/USD as 1.08456 versus 1.08460? In terms of pips, that's four (4) pipettes of difference! In the end, that could determine if a trade is a gain (at target) or a loss (at your stop loss).
Common Mistakes Traders Make with Decimals
Mixing up pips with pipettes is a frequent mistake. A trader might think that they are setting a five pip stop loss but has instead set it to five pipettes (0.5 pips), leaving their position wide open. Conversely, the trader may have meant to set a five pip stop and accidentally set a stop for 50 pips, which is exposing them to much more risk than they originally intended.
Another mistake is paying little attention to the decimal differences between brokers. For example, two brokers may say they have "tight spreads", but the first broker quotes the EUR/USD at 1.08456/1.08466 (a 1.0 pip spread) while the second broker quotes the EUR/USD at 1.08456/1.08476 (a 2.0 pip spread). If there is a lack of attention to the decimals, then it would be easy to not catch that a trader is paying double the spread on the second broker.
Mastering Decimals to Trade Smarter
Decimals are the basis of being precise in forex trading, a large part of what enables you to measure price movement accurately, how close your spreads are, and how you can handle your risk and reward calculations accurately. Learning to understand decimals allows you to trade more confidently and accurately whether you're a scalper looking to profit off quick moves, or position-trader holding onto trades for weeks.
It's all about pips, and even the pipette that resides within the pip when you're risking real money. Sometimes the difference between trade profits and losing trades can often come down to these tiny details. If you can operate with precision in your decimals, then you can better time your entries and exits, manage your risk and avoid the emotional mistakes that come with miscalculating how forex prices work.
