The most basic of all four charts is the line chart, because it shows only the closing price over a specified period. The line chart is created by connecting a series of data points together in a line.
The right side of the chart shows the currency values that generally run below or above the lowest and highest prices reached during a specific period.
A bar chart gives four key pieces of information for any given period. These include the opening price during that period; the closing price, the low price and the high price. Bar charts can summarize activity over the past minute, hour, day or even month.
Candlestick charts indicate the high / low range with a vertical line, as in any bar chart. In candlestick charts, the larger blocks indicate the price range between the opening and closing prices.
