With the price change tool, you can measure the price difference between two points in a chart. The difference can be displayed both as an absolute value or as a percentage.
The price change tool needs two reference points, that will be compared with each other. The start point (A) is used as the reference point or base value, the end point (B) is used as the target point to calculate the difference.
You can choose which of the calculated values are displayed on the chart, move the reference point of the price change object to a selected value, and change the line style of the object: See Customizing Price Change.
▪ Click on the Price Change icon on the Drawing toolbar:
▪ Click on the chart at the first reference point (start point) and hold the mouse button down.
▪ Move the mouse pointer to the second reference point (end point) and release the mouse button.
