Select the first date on the chart using F12, then the last date with Shift+F12. You will see the percentage change in the price and the number of days between the two selected dates on your chart (top right). You can change the value used to Open, Close, etc.

The formula works fine. You probably have an old version of Amibroker that doesn’t support Gfx functions.

You can also select two points on the chart by double clicking on the chart in one spot then double clicking in another spot.
