The Forex Market Chart

There are different chart formats and these can be available, provided by your brokers. These are

• Line chart,
• Bar chart, and 
• Candlestick chart. 

Out of the 3 charts, Candlestick chart is widely used throughout the world. 

Normally these charts would at least (or only, for line chart) show the closing price of the currency pair you are trading. However your broker's platform might enable you to view the chart based on other factors, such as the opening price, average price, and etc.
