Relative Strength Index exponential (RSI) – 14D works just like RSI -14D and measures the speed and change of price movement to determine whether a stock is in overbought or oversold range. RSI exponential above 80 indicates that the stock has run up to much, whereas a reading below 20 indicates an oversold position.

RSI exponential is calculated using exponential average of price close of stocks, for previous 14 tradable days. An exponential moving average is a type of moving average that is similar to a simple moving average, except that more weight is given to the latest data.
