How Does Relative Strength Index Help in Stock Trading?
The Relative Strength Index, or RSI, is a technical analysis indicator designed to help stock chart readers analyze the price behavior of stocks and other securities. The RSI is usually plotted at the bottom of a price chart as a line on top of a graph that ranges between zero and 100. RSI is created by a formula that tells analysts if the price of a stock is strong or weak in relation to the S&P 500 index.
