*What is a relative strength index?
Relative strength index is a technical momentum indicator that compares the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions of an asset.
An asset is viewed as overbought once the RSI approaches the 70 level, meaning that it may be getting overvalued and is a candidate for a possible pullback. Conversely, if the RSI approaches 30, it is an indication that the asset may be oversold and may become undervalued.
