Chart

Market analysts use charts to plot the price movements of a financial instrument over specific time frames. It is a graphical method of showing where prices have been in the past.

A chart has an x-axis (horizontal) and a y-axis (vertical). Typically, the x-axis represents time; the y-axis represents price. By plotting a financial instrument’s price over a period of time, we end up with a "pictorial representation of any financial instrument’s trading history.

A chart can provide a complete picture of a price history over a period of an hour, day, week, month or many years.

A chart can also show the history of the volume of trading in a financial instrument over a certain time period.

Technical analysts rely on a wide variety of charts in their work.
