What is a Relative Strength Index (RSI)?

1. Overview

The Relative Strength Index (RSI) is a technical analysis indicator used to measure the magnitude of recent price changes in a security or currency. It is a momentum indicator that helps traders identify potential trend reversals or overbought/oversold conditions.

2. Formula

The RSI is calculated using the following formula:

RSI = 100 - 100 / (1 + RS)

where:

RS is the Average Gain / Average Loss

3. Interpretation

The RSI value ranges from 0 to 100:

Overbought Zone: RSI values above 70 indicate that the security may be overbought and due for a correction.
Oversold Zone: RSI values below 30 indicate that the security may be oversold and potential for a bounce back.
Neutral Zone: RSI values between 30 and 70 indicate that the trend is not clearly defined.

4. Usage

Traders use RSI in the following ways:

Trend Reversals: RSI divergences can signal potential trend reversals. When the price action makes a new high but the RSI does not, it's a bearish divergence and vice versa.
Overbought/Oversold Conditions: Identifying overbought or oversold conditions can help traders avoid chasing volatile markets that may be due for a correction.
Trading Strategies: RSI can be incorporated into various trading strategies, such as:
- Buying when RSI crosses above 30
- Selling when RSI crosses below 70
- Using RSI divergences to identify potential trading opportunities

5. Advantages

Provides insights into market sentiment and momentum.
Helps identify potential trend reversals and overbought/oversold conditions.
Can be combined with other technical indicators for enhanced analysis.

6. Limitations

RSI is a lagging indicator, meaning it responds to price action after it has already occurred.
It may be susceptible to false signals in volatile or sideways markets.
RSI should not be used as a sole decision-making tool, but rather in conjunction with other analysis methods.
