Relative Strength Index Formula
The relative strength index formula is a momentum oscillator formula that compares upward movements of the close price with downward movements, and outputs values from 0 to 100. A value close to 100 indicates that the price is about to move downward, and a value close to 0 indicates that the price is about to move upward.
