Traders and investors always look at charts when they make trading decisions, because those charts contain essential information about the behavior of prices. Here are some familiar types of charts that facilitate performance analysis.

Line Chart

Bar Chart

Candlestick Chart

Candlestick charts are very popular in Asia. Essentially, they contain the same information as bar charts. Figures 3 shows an example of a candlestick chart:
