What Is the RSI Indicator
The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of price movements.
The indicator moves between 0 and 100 and helps traders determine whether a market may be overbought or oversold.
Most traders focus on two important levels:
70 – Overbought level
30 – Oversold level
When the RSI rises above 70, the market may be overbought and a price correction could occur.
When the RSI falls below 30, the market may be oversold and the price may start moving upward again.

How the RSI Indicator Works
The RSI analyzes recent price gains and losses to measure market momentum.
The most common setting used by traders is 14 periods, which provides a balanced view of market conditions.
The RSI appears as a line below the price chart and constantly moves between 0 and 100, showing how strong the recent price movement has been.

RSI Trading Strategy (Simple Method)
One of the easiest ways to use the RSI indicator is the overbought and oversold strategy.
Buy Signal
A buy signal may appear when:
The RSI falls below 30
Then moves back above 30
This indicates that the market may be leaving an oversold condition and a potential upward movement could start.
Sell Signal
A sell signal may appear when:
The RSI rises above 70
Then moves back below 70
This suggests that the market may be leaving an overbought condition and a downward correction could occur.

Advantages of the RSI Indicator
The RSI indicator offers several advantages for traders:
Easy to understand and use
Helps identify potential reversal points
Works on many markets and timeframes
Suitable for beginners and experienced traders
Limitations of the RSI
Like all technical indicators, the RSI has some limitations.
During strong trends the indicator may remain overbought or oversold for extended periods. Because of this, traders often combine RSI with other indicators such as moving averages or support and resistance levels.
