What is the Relative Strength Index (RSI)?
The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of price movements. It was developed by J. Welles Wilder and introduced in his 1978 book, New Concepts in Technical Trading Systems.The RSI oscillates between 0 and 100. Traders use the RSI to identify overbought and oversold market conditions. It is also used to identify divergences, failure swings and to forecast reversals.
How to Calculate the Relative Strength Index (RSI)
The RSI is calculated using the following formula:RSI = 100 – (100 / (1 + (Average of Upward Price Change / Average of Downward Price Change)))The Average of Upward Price Change is the average of the upward price changes over the specified period. The Average of Downward Price Change is the average of the downward price changes over the specified period.
How to Interpret the Relative Strength Index (RSI)
The RSI is considered overbought when it is above 70 and oversold when it is below 30. Traders may also look for a move above or below 50 to indicate a trend.When the RSI is above 70, it indicates that the market is overbought and a downward correction may be expected. When the RSI is below 30, it indicates that the market is oversold and an upward correction may be expected.
How to Use the Relative Strength Index (RSI) in Forex Trading
The RSI can be used in a variety of ways in forex trading. It can be used to identify overbought and oversold levels, to identify divergences, to identify failure swings and to forecast reversals.
Identifying Overbought and Oversold Levels
The RSI is considered overbought when it is above 70 and oversold when it is below 30. When the RSI is above 70, it indicates that the market is overbought and a downward correction may be expected. When the RSI is below 30, it indicates that the market is oversold and an upward correction may be expected.
Identifying Divergences
Divergences occur when the price of an asset is moving in one direction while the RSI is moving in the opposite direction. This can be used to identify potential reversals in the price of the asset.
Identifying Failure Swings
Failure swings occur when the RSI moves above 70 and then back below 70 without reaching a new high. This can be used to identify potential reversals in the price of the asset.
Forecasting Reversals
The RSI can be used to forecast potential reversals in the price of an asset. When the RSI moves above 70 and then back below 70 without reaching a new high, it can be used to identify potential reversals in the price of the asset.
