Basic Chart Types: Understand the Different Ways Data Are Displayed

Reading Time: 8 Minutes

All financial markets generate data.

To effectively assess this data, charting solutions are necessary.

Technical analysts, or ‘chartists’, employ the use of charts to evaluate price action for the purpose of trend and pattern identification in a broad range of markets. This includes asset classes such as foreign exchange (Forex market), equities, equity indexes, commodities and cryptocurrencies.

Presented through an easy-to-read graphical format, a chart displays the collective trading decisions of all market participants over a specified timeframe. For example, hourly time periods are made up of consecutive hourly data points that provide users a magnified view of market action. Daily charts, on the other hand, are composed of intraday data, compressed to show each day as a single data point.

The line chart, the bar chart and candlestick chart are among the most widely used in technical analysis, each boasting unique differences. It’s important to note the y-axis on most charts (vertical panel usually plotted to the right of a chart) indicates price scale and the x-axis (horizontal panel arranged at the bottom of the chart) represents time scale.

Basic Chart Types—Methods of Observing Trading Activity

Line Chart:

Composed of a continuous line calculated through closing prices, line charts are popular with market participants who consider closing prices most important. Price changes are ‘smoothed’ with line charts as high, low and open-price data (highs and lows are often referred to as ‘upper and lower shadows’ or ‘wicks’) are disregarded. Figure A shows a line chart for spot gold (XAUUSD) using daily closing prices.

Financial journalists regularly make use of line charts to demonstrate relationships between different financial markets. Figure B presents the relationship (or correlation) between the EUR/USD currency pair and the ICE US Dollar Index (USDX) futures contract.

Line charts are also convenient to help reveal longer-term trends (uptrends and downtrends), and can be particularly useful to determine support and resistance levels (horizontal lines). This, as underlined above, is primarily due to the ‘filtering effect’—filtering high, low and open data.

Bar Chart:

Unlike the line chart, the western bar chart—sometimes referred to as ‘OHLC’ charts—visually displays individual open, high, low and close (OHLC) data of a security across different time periods. This could be daily bars, hourly bars, 15-minute bars or even 1-minute bars. For example, figure C illustrates the OHLC structure of a bar chart, showing EUR/USD on the daily timeframe and the short-term H1 timeframe.

The open represents the price level the bar begins its formation; the close is the point the market concludes trade during its time period. The left horizontal dash is the opening price and the horizontal dash on the right of the bar signifies the closing price. A bar high indicates the highest point the market was bought during the bar’s life; equally, the low signifies the lowest point the market was sold. Additionally, the bar’s body represents the difference between the open and close.

Bar charts clearly reveal additional information. The key difference between a line chart and a bar chart is the bar chart shows volatility. An increase in volatility generates larger (or wider) bars, while quieter sessions (less volatility) produce smaller (or more contracted) bars.

Candlestick Chart:

Serving as a variation of the bar chart, the candlestick chart is a popular way of viewing market data. Candlestick charts and candlestick patterns originated in Japan, and have been popularised by Steve Nison. If you’re interested in learning the history of candlestick charts and patterns, Nison’s book: Japanese Candlestick Charting Techniques, is a worthwhile read.

Although made up of the same data as a bar chart, a candlestick chart delivers a more graphic format of OHLC values which, for many traders is easier to read. The candlestick’s real body (between opening and closing prices) is prominent and filled, allowing traders to rapidly determine price direction—bar charts display the body by way of a vertical line.

Bullish and bearish candles demonstrate similar characteristics. The key differences are colouring of the candle, along with open and close prices—they’re reversed. The open for a bearish candle is at the upper range of the candle; for a bullish candle the open is situated at the lower range.

Figure D illustrates bullish candles in green and bearish candles in red.

Closing Notes

Both western bar charts and Japanese candlestick charts permit traders and investors to apply a wide array of technical indicators and allow for chart pattern recognition. However, as alluded to in the article, candlestick charts are the more preferred choice among technical analysts.

Trading strategies often include candlestick patterns, such as the doji, hammer and shooting star formations. On top of this, the beneficial aspect of candlestick charts, aside from sharper visualisation, is market participants can combine western chart patterns—think double-bottom and double-top patterns—to help forecast future price.
