The Hull Rate of Annual Decline indicator is used to calculate the annual rate of decline of a share given its current rate of fall. It achieves this by calculating the annual decrease in price activity and then dividing it by the current share price. The result is then multiplied by 100 to convert it to a percentage. For more information on this tool, please visit Alan Hull’s website.
