What is the RSI?

The Relative Strength Index (RSI) is a popular momentum oscillator used in technical analysis to measure the speed and change of price movements. Developed by J. Welles Wilder Jr., it ranges from 0 to 100 and helps traders evaluate whether a security is overbought or oversold. The RSI typically uses a 14-period timeframe and is calculated based on the average gains and losses over that period. A rising RSI suggests increasing buying momentum, while a falling RSI indicates growing selling pressure.

RSI overbought

When the RSI rises above 70, the asset is generally considered overbought. This condition indicates that the price may have risen too quickly and could be due for a correction or pullback. However, being overbought doesn't automatically mean a reversal will occur, it signals that bullish momentum is strong, and traders should be cautious of potential trend exhaustion.



RSI oversold

Conversely, an RSI reading below 30 is typically seen as a sign that the asset is oversold. This condition suggests the price may have fallen too sharply and could be primed for a rebound. Just like with the overbought condition, an oversold RSI doesn’t guarantee an immediate reversal but serves as a warning that bearish momentum may be overextended.



RSI divergences

Divergences occur when the RSI and the price of the asset move in opposite directions. A bullish divergence happens when the price makes a lower low, but the RSI forms a higher low, potentially signaling a reversal to the upside. A bearish divergence occurs when the price makes a higher high, but the RSI creates a lower high, possibly indicating a downward reversal. Divergences are often used to spot early signs of trend changes.





How to use the RSI?

To use the RSI effectively, traders typically look for overbought and oversold conditions to time entries and exits, combine it with other technical indicators for confirmation, and watch for divergences as a sign of potential reversals. RSI can also be adapted for different timeframes or strategies, depending on whether the trader is looking for short-term swings or long-term trend analysis. While it’s a powerful tool, RSI should not be used in isolation, it works best as part of a broader trading plan that considers market context and risk management.

How to trade with the RSI?
The RSI can be a powerful tool for identifying potential trade setups. When the price approaches a key support zone while the RSI remains in overbought territory, this may signal an early warning of a possible market reversal. However, rather than acting immediately, it's wise to wait for confirmation. A clear candlestick reversal pattern, such as a bullish engulfing candle or a pin bar, a provide stronger evidence that momentum is shifting. By combining RSI readings with price action and support levels, traders can improve the accuracy and timing of their entries.
