A Forex chart is a graph that displays price fluctuations over a certain period of time. It is a powerful tool that can greatly help you analyze the events of the market and execute your trading decisions when the moment is just right. Over the years, traders have come up with multiple chart types: candlestick, bar charts, line charts, etc. All of them offer a varying amount of details, but their principal purpose is to show historic, present, and expected performance of a stock.
