Relative Strength Index
Description
The Relative Strength Index was introduced by Welles Wilder. The Relative Strength Index compares upward movements in closing price to downward movements over a selected period. The RSI should not be confused with the relative strength indicator which is used to compare stocks. This script displays the upper and lower thresholds and fills any excursion above the upper or below the lower with a fill color.
