What is an RSI indicator? The use of RSI indicators in the cryptocurrency sector

In currency circle trading, judging buying and selling timing is very important, and the Relative Strength Index (RSI) is a common and practical tool. It can help you see whether a coin is \"overbought\" or \"oversold\". Simply put, it tells you whether it is risky to chase high or low points are worth paying attention to. This article will teach you the basic principles and usage of RSI in an easy-to-understand way, so that you can have more confidence in cryptocurrency trading and no longer blindly follow suit.

What is an RSI indicator?

The Relative Strength Index (RSI) is a widely used technical indicator in stock trading and analysis. It was developed by J. Welles Wilder to measure the speed and degree of change in price changes. RSI is classified as a momentum oscillator that evaluates the strength and speed of price changes, thereby helping traders identify possible overbought or oversold conditions.

RSI values are usually between 0 and 100. When the RSI exceeds 70, it usually means that the asset may be oversold and there may be a price correction or reversal; when the RSI is below 30, it usually means that the asset may be oversold and the price may rebound.

RSI is calculated by calculating the average increase and decrease over a certain period (usually 14 trading days), then dividing the average increase by the average decrease, and converting the result to a value between 0 and 100.

RSI formula and calculation

Here is how to gradually calculate the relative strength index:

Step 1: Price change (Δt)

This is the difference between the current closing price and the previous closing price:

Δt= price t-price t-1

Explanation: For each cycle (usually 1 day), the current closing price is subtracted from the previous closing price. This results in a daily gain or loss.

Step 2: Distinguish gains and losses

Gain t=max(Δt,0)

Loss t=max(-Δt,0)

Explanation: If the price rises, the gain is recorded and the loss is zero. If the price falls, the gain is zero and the loss is the absolute value of the change. This distinction is key to understanding upward momentum and downward momentum.

Step 3: Calculate the initial average gains and losses

Average gains 14=(total gains over 14 cycles)/14

Average losses 14=(total losses over 14 cycles)/14

Explanation: Take the average of the previous 14 gains and losses first. These are simple arithmetic averages that are used as seed values for subsequent smoothing steps.

Step 4: Smooth the average (Wilder\'s method)

Average gain t=((Average gain t-1×(n1))+ gain t)/n

Average loss t=((Average loss t-1×(n1))+ loss t)/n

Explanation: Instead of recalculating the entire average every time, it is better to use a smoothing method such as an exponential moving average. This approach can give more weight to recent data without being too passive. The standard cycle n is 14.

Step 5: Calculate relative intensity (RS)

RS t= average gain t/average loss t

Explanation: The relative strength indicator compares bullish and bearish momentum. A value greater than 1 means that the recent increase is greater than the decrease;

Step 6: Calculate the RSI

RSI t=100-(100/(1+RS t))

Explanation: The final formula compresses RS to a value of 0-100. If RS=1(equal profit/equal loss), then RSI=50. Above 70 usually indicates overbought, and below 30 indicates oversold, but these thresholds can be adjusted based on the strength of the trend.

In practice, traders often use RSI to look for buy or sell signals. If the RSI is above 70, traders may consider selling assets; if the RSI is below 30, it may be a buy signal.

Application of RSI in the cryptocurrency field

The following are some common uses of RSI in the cryptocurrency market:

1. Identify overbought and oversold states: The most basic function of RSI is to determine whether it is overbought or oversold. When the RSI is above 70, it means that it may be oversold and there is a risk of decline; when the RSI is below 30, it means it may be oversold and there is a possibility of rise.

2. Confirm trend strength: RSI can help determine the strength of the current trend. In a strong uptrend, the RSI may remain in oversold territory for a long time; in a downtrend, the RSI may remain in oversold territory.

3. Discovering divergence signals: When the price trend of the cryptocurrency and the trend of the RSI indicator are in the opposite direction, a divergence will occur. If prices hit new lows and the RSI did not hit new lows, this \"bull market divergence\" could mean that the trend will reverse upwards; conversely, if prices hit new highs but the RSI did not hit new highs, this \"bear market divergence\" could be a sign for a turn down.

4. Determine potential reversal points: Extreme RSI values may mean that the trend is about to reverse. If a currency\'s RSI remains at a high position for a long time, it may mean that a decline is about to occur; conversely, if the RSI remains at a low position for a long time, it may indicate that a rise is about to begin.

5. As a reference for support and resistance: Certain numerical areas of the RSI can be used as support or resistance. For example, if the RSI often rebounds around 40-50, this area may be support; if the RSI often encounters resistance between 60-70, this area may be resistance.

6. Use in conjunction with other indicators: Traders often use RSI in conjunction with other technical indicators (such as moving averages, MACD, trend lines) to verify trading signals.

7. Adjust trading strategies: RSI values can help traders optimize trading strategies. For example, you can consider taking profit when the RSI shows oversold; you can consider buying when the RSI shows oversold.

8. Used for intraday trading: In fast-paced intraday trading of cryptocurrencies, RSI can help traders judge short-term price fluctuations and make quick decisions.

Tools and platforms for tracking RSI in cryptocurrencies

Effectively tracking RSI indicators requires appropriate tools tailored to the rapidly changing market for cryptocurrencies. These tools range from universal trading platforms to professional cryptocurrency trackers, providing different levels of functionality and customized services.

Popular cryptocurrency RSI tool

TradingView is a popular charting platform known for its powerful RSI analysis capabilities. Users can easily superimpose RSI on a price chart, customize its settings, and even apply community-created scripts to implement advanced strategies. Its intuitive interface is easy for beginners, while its advanced tools are suitable for experienced traders.

For example, you can use TradingView to analyze Bitcoin\'s RSI over different time frames and adjust between standard 14-day cycles or settings tailored to your strategy.

The platform also offers multi-time horizon analysis, custom options, and a wide range of community-shared metrics, making it the preferred resource for detailed RSI tracking and strategy development.

MEXC, the leading cryptocurrency exchange, also offers powerful RSI tracking tools within its trading platform. By integrating advanced charting capabilities, MEXC allows users to seamlessly analyze RSI trends while managing transactions in real time.

RSI Heat Map and Tracker

Cryptocurrency-specific tools such as RSI heatmaps and trackers are ideal for quickly measuring RSI trends across multiple assets. Cryptocurrency RSI heatmaps provided by platforms such as CryptoQuant and IntoTheBlock can visually display aggregated RSI data for various tokens.

These heat maps are particularly useful for identifying investment opportunities at a glance. For example, if the heat chart shows that most altcoins have an RSI below 30, this may indicate that the market is oversold as a whole and there is a potential buying opportunity.

At the same time, custom RSI trackers provided by tools such as CoinGecko and Messari allow traders to monitor the RSI of specific tokens or portfolios. These platforms provide a more personalized RSI trend tracking method to ensure that you are kept up to date on the latest developments of your selected assets.

Set alerts and customization options

Setting RSI alerts ensures that traders do not have to continuously monitor charts. Platforms such as TradingView can easily set up notifications that are triggered when the RSI exceeds a certain threshold (such as 30 or 70) or a deviation occurs. For example, you can configure an alert to notify you when Bitcoin\'s RSI falls below 30 on the 4-hour chart, which signals a potential buying opportunity.

These alerts are highly customizable, allowing traders to adjust thresholds or time frames based on their strategy. For short-term trading, consider setting alerts at a more sensitive RSI level (e.g. 80/20) to catch rapid market fluctuations.

Long-term traders may prefer to use standard levels such as 70/30 to focus on broader trends. Regardless of your trading style, these features ensure that you always have key RSI signals.
