A Forex chart and visualization of price movements

In Forex, just like in any other market, the asset prices make a certain movement: sometimes they go up and sometimes they go down. This is the movement that the traders use to either buy or sell the currency pairs. If the price is low and is showing signs that it will soon increase, traders will tend to buy the asset, while when the price is high and is slowly decreasing, traders will sell the asset.
 
Sometimes, observing these prices and analyzing them can be difficult with tables filled with lots of numbers. To make the price movements easier to understand, traders use a visualization method called a Forex chart.

How to read Forex charts?

The FX charts, just like the ones available for other assets, make the bid and ask price movements much more apparent and easy to observe. Usually, these movements will be shown in lines, columns, or any other form. As for the time frame, the prices will be recorded against a tick (the smallest change in price), a minute, an hour, a day, or above.
 
 
All charts, be it for currencies, commodities, etc. have basically the same layout in terms of the price and time representations. The x-axis (which is the vertical line) shows the time along which the price went up or down; the y-axis (which is the horizontal line) shows the price at a certain time.

Because there is a time dimension in a chart, traders can view the prices that were quoted in the past. And since we’re reading Forex charts, this price will be an exchange rate of the currency pair. And depending on which time frame a trader chooses, the price movements will be shown in ticks, minutes, hours, days, or even years - and it is pretty easy to go from one to another by zooming in or out.

Different types of Forex charts

Almost all Forex brokers offer free charts to their clients that are included in their trading package. And when traders download MetaTrader 4, MetaTrader 5, or cTrader (trading programs), the charts will automatically be available for them. Apart from brokers and their trading software, there are also third-party charting programs like TradingView that provide currency price charts for free.
 
Now, while every chart represents a price movement in a certain time period, whether it’s in Forex, stocks, or in any other market, there are various Forex chart types that have different visualization methods. Namely, the most popular charts are:
 

• Line charts
• Bar charts
• Candlestick charts

 
Let’s take a look at each of them.

Line charts

In Forex, a line chart is the most basic and simple price representation. Basically, it marks various price points of a certain asset on the diagram and then connects the neighboring points to each other with a continuous line.
 
Now, while line charts are very simple to understand, they’re too simple, actually. That’s because they only depict the closing prices of currency pairs. So traders who want to get more complex information like opening or highest/lowest prices, the line chart wouldn’t provide that to them.

Bar charts

Unlike the line FX chart types, bar charts are more complex and offer even more prices than the previous one. Basically, this bar represents four different prices of a currency pair in a given time period - either minutes, hours, days, or higher.
 
Here are those four prices: the top and bottom ends of the bar represent the highest and lowest prices of the asset in that time period; a short vertical line on the left shows the opening price and the same one on the right shows the closing price.


Bar charts are far more complex than line charts for obvious reasons: while the line chart represents one price, the bar chart does that for four different prices. But when it comes to the most complex chart type, even the bars aren’t enough.

Candlestick - the most popular FX market chart

That’s why there are candlestick charts that basically combine the two previous types. A candlestick chart is the most popular method for visualizing Forex price movements in a given period of time.

While bar charts only show four prices in just one time period, and line charts only show one price in a longer time frame, the candlestick chart shows four prices in a longer time frame (depending on trader’s preferences). In short, the individual bars are arranged in a given time period and they show opening/closing and high/low prices of a currency pair.

In this chart type, the space between the short vertical lines (open/close) is called the “real body” and it indicates whether a trader had a successful trade or not. If the real body is white/green, this means that the opening price was lower than the closing price and the trader sold a pair at a higher price and gained a payout. And if the real body is black/red, the opening price was higher than the closing price, which means the trader sold a pair at a lower price and lost some funds.

Trading Forex charts in technical analysis

Now that we have explained what charts are in Forex and what types are the most popular, one question remains unanswered: why do traders use Forex charts?
 
 
In trading, whether it’s Forex, stocks, commodities, or anything else, there is a method called technical analysis which is where these charts come in useful. As we have mentioned above, traders use charts to see the historical price movements of their assets and make certain conclusions.
 
Technical analysis in Forex is basically a method of reading charts and speculating, whether the price of a Forex pair will increase or decrease in the future. There are two possible scenarios that can be “read” from charts:
 

• If the exchange rate of a pair is increasing from the left side of the chart to the right side, it means that the market is in an upward trend - it’s basically expanding and buyers are in a favorable situation;
• If the exchange rate is declining from the left side of the chart to the right side, it means that the market is in a downward trend - it’s contracting and sellers are in an unfavorable situation.

 
These scenarios may seem very simple but usually, such trends prove to be long-term. However, that’s not to say that the live chart Forex diagrams always lead to correct conclusions and that they are always right. That’s because they are not. In some cases, the upward/downward trend may change dramatically because of a sudden occurrence on the market. That’s why we used the term “speculation” to describe this method.
