Apart from their geometrical or artistic forms, charts are very important tools that allow technical analysts to draw technical indicators. These indicators are measures of a stock's price, volume movement and investor sentiment over time and on any market
Charts come in many different types: bar charts, lines charts, point and figure graph and candlestick charts.
Bar chart is a vertical line on a graph that link the bottom (low price) and the top (high price) of a trading period
Line charts is the graphical drawing of line that connects a series of stock close prices during a certain period: hourly, daily, weekly or monthly.
Point and figure graph
Point and figure graph is a very complex charting method to be covered broadly in this article. Just note that Point and figure graph is obtained by drawing on paper X and O as a representation of each price change. Unlike bar , the construction of Point and figure chart does not take into account the element of time, and therefore cannot be used with volume or other technical indicators that depend on session information.
A candlestick chart is the graphical representaion of stock price movements in form of a candle. Each candlestick body displays the difference between the opening an closing price. The Candle shadow indicates the price activity above and below the body.
