RSI by zdmre

Traditional interpretations and usage of the RSI dictate that values of 70 or above suggest that a security becomes overbought or overvalued and may be primed for a trend reversal or corrective price pullback. An RSI reading of 30 or below indicates an oversold or undervalued condition.

30 = Oversold 70 = Overbought

Thanks @DieGobelMonte for your suggestion.
