With different types of traders functioning differently, the model of the graph will also change and be interpreted accordingly. Trends can be used by a day trader to watch the change in prices in minutes to those whose investment is persisting to years. There are different kinds of trends like uptrend and downtrend . The upper trend always tends to show positive values and the downtrend will have negative values. The traders need to closely watch the change in trends to get profitable from trading in stocks.

Volumes are also important in the stock chart. They are represented as histograms in the down pane of the chart. There is a red graph and a green graph wherein the red graph is for the days when the stock is up and green graph is for the days when the stock is down . Moving average is another important technical term in the stock chart as it represents the average price of a particular stock for a particular amount of time.
