The Relative Strength Index (RSI) is a popular technical analysis indicator used to measure a stock's relative strength. It compares the magnitude of recent gains to recent losses in an attempt to determine an asset's overbought and oversold conditions, and it ranges from 0 to 100. A stock with an RSI above 70 is considered overbought and likely to experience a price decline. In contrast, a stock or other asset with an RSI below 30 is considered oversold and likely to experience a price increase. In the stock screens at the link below, you can view tickers that are overbought or oversold or stocks with RSI that is in divergence or trending. You can also customize the stock screener criteria, develop a trading strategy and backtest it on historical data.

The Relative Strength Index ("RSI") is a popular oscillator. Welles Wilder first introduced it in an article in Commodities Magazine in June 1978. When Wilder introduced the RSI, he recommended using a 14-day RSI. Since then, the 9-day and 25-day RSIs have also gained popularity. Because you can vary the number of periods in the RSI calculation, you should experiment to find the period that works best for you - the fewer days used to calculate the RSI, the more volatile the indicator.
