What it is:
How it works (Example):
A point-and-figure chart records and displays specific whole-number changes in the price of an asset. In other words, unless a change is large enough to accommodate this amount, referred to as a box, the change is not recorded (e.g. a change of $0.50 where a box size is $1.00 would not be recorded). The price scale is on the y-axis with no time series or other variable on the x-axis. Upward price changes are generally shown with an "X" and downward changes with an "O" as shown below:
Changes are recorded from left to right with each column exclusively displaying Xs or Os as price changes occur. Consecutive changes in the same direction are recorded in the same column. For this reason, a change in the direction of a price movement (i.e. from positive to negative) is represented by a new column. Multiple columns, therefore, always alternate between Xs and Os and no two consecutive columns can begin or end on the same line (i.e. price level).
Why it Matters:
Point-and-figure chart patterns indicate imminent increases or decreases based on price history. In this respect, point and figure charts are a tool used to help traders and investors determine the best time to buy or sell.
