Line chart

X-Trade Brokers say this is the most basic charting-based tool to represent the price evolution. The line is formed by connecting the dots in a range of data. The dots may represent the opening prices, on peaks and troughs, or closing prices. The most commonly used are the closing prices, considered to be the most relevant.

The main advantage is the simplicity and its drawback is the lack of details over the time frame represented by one dot.
