Relative Strength Indicator


The Relative Strength Indicator function is based on the indicator developed by J. Welles Wilder. It compares the average of up closes against the average of down closes over a specified number of time periods. Resulting values range from 0 to 100. Applications of RSI include identifying overbought or oversold situations. For example, if the RSI line stalls at a level above 70, this may indicate the stock is overbought. Or, if the RSI line drops to a level below 30, this may indicate the stock is oversold and becoming undervalued.
