What is the RSI Indicator?: A Complete Guide


Technical analysis involves spotting early signals of price shifts, retracements, and trend reversals, making it essential for traders. This field encompasses various indicators aiding in price movement assessment. These indicators can be classified into two groups: leading and lagging. Leading indicators anticipate price movements while lagging ones trail behind them. One such popular lagging indicator is the Relative Strength Index (RSI).

The RSI serves as a gauge for recent price movement intensity in a market or asset, helping identify overbought or oversold conditions. It operates as a momentum oscillator, ranging from 0 to 100. This article will delve into its functionality, calculation method, and applicability across diverse financial instruments.

How Does the Relative Strength Index (RSI) Work for Crypto?

The Relative Strength Index (RSI) evaluates whether a crypto’s price is excessively bought or sold by assessing recent price movements through a specific formula. To pinpoint overbought or oversold conditions, when the RSI surpasses 70, the crypto is considered overbought, signaling a potential correction in the bullish trend. Conversely, when it falls below 30, it’s deemed oversold, suggesting an impending rebound.

In a robust uptrend, the RSI often exceeds 70 for prolonged periods, while in a downtrend, it frequently lingers at 30 or below. Traders utilize the RSI to identify buying opportunities during oversold conditions in bullish trends. Conversely, in bearish trends, they seek selling opportunities when the price becomes overbought. An RSI above 50 indicates increased buying momentum and stronger market buying power, whereas an RSI below 50 indicates heightened bearish sentiment. Monitoring price activity around the 50 level helps discern potential shifts between bullish and bearish trends.

RSI divergence arises when the price and RSI oscillator move in opposite directions, suggesting a potential shift in market momentum. For instance, a bullish divergence occurs when the price hits a new low while the RSI doesn’t, typically signaling a buying opportunity. Conversely, a bearish divergence manifests when the price achieves a new high while the RSI records a new low, indicating diminishing momentum and a potential reversal in the upward trend. 

Understanding RSI divergence empowers traders to anticipate market momentum shifts and adjust strategies accordingly. Integrating RSI divergence with other technical indicators can bolster trading signal accuracy and overall performance.

Calculating RSI: It’s Simpler Than You Think

You can get a basic understanding of RSI through the provided formula. This calculation includes averaging price gains and losses across a specified timeframe.

The RSI is computed as follows: RSI = 100 – [100 / (1 + (average upward price movement / average downward price movement))] 

RSI in Different Financial Instruments


The RSI serves as a valuable tool for crypto traders, guiding them to optimal entry and exit points. For instance, traders may opt to sell when the RSI exceeds 70, indicating a potential exit point, or they might consider buying when the RSI falls below 30 as a signal to enter a trade. Swing trading, a strategy centered on capitalizing on short-term price fluctuations, often relies on indicators like the RSI to determine buy and sell signals. For instance, traders might initiate a buy order when the RSI dips below 30 and execute a sell order once it surpasses 70, subsequently repeating the process when the RSI dips below 30 again.

Bullish RSI divergence, characterized by higher lows in price coupled with declining lows in RSI, can signal potential opportunities, particularly when RSI ventures into oversold territory. Conversely, bearish RSI divergence, featuring higher highs in price against lower highs in the RSI, might prompt some traders to consider selling.

Advantages of Using the RSI Indicator

There are numerous advantages associated with utilizing RSI, some of which are outlined below:


One of the primary benefits of employing RSI in crypto trading is its simplicity. It entails a straightforward calculation based on the average gains and losses over a specified timeframe. This information empowers crypto traders to pinpoint potential entry and exit points with ease.

Clear Identification of Overbought or Oversold Trends:

RSI facilitates the identification of overbought and oversold trends within the crypto market. When the RSI surpasses 70, it signals that the crypto is overbought, potentially indicating an impending trend reversal or correction. Conversely, when the RSI falls below 30, it suggests that the crypto is oversold, presenting a potential buying opportunity.

Confirmation Tool:

Moreover, RSI serves as a valuable confirmation tool for validating trends and breakouts in the crypto market. During an uptrend, the RSI typically remains above the 50 level, signaling the presence of bullish momentum. Conversely, in a downtrend, the RSI tends to stay below 50, indicating prevailing bearish sentiment. By utilizing RSI as a confirmation tool, traders can validate the strength of a trend before initiating a trade.


The RSI stands out as a pivotal tool for many crypto traders to decipher price momentum. Given that momentum holds significant importance in crypto trading, the RSI is particularly well-suited for this asset class. It is most effective when asset prices oscillate between bullish and bearish phases within a trading range. Crypto traders should leverage several crypto technical indicators to enhance decision-making and should not solely rely on one.
