See the discussion of the use of Trendlines and Three Simple Rules. The following basic types of price charts are the most commonly used. In most cases indicators are shown superimposed on the price chart itself or in a separate chart below the price chart. Most of the analytical tools compare the action of an indicator against that of the price. This is the most common type of chart used.
Time is factored into the price movements.
Volume charts often accompany bar charts. This tends to smooth out daily fluctuations in price, sometimes giving a better picture of the overall trend. Unlike the other basic charts, time itself is not a factor. Point and figure charts plot only the direction of a price move and the change in value. Proponents believe this gives them a clearer view of the underlying actions of supply and demand.
