RSI Indicator

The Relative Strength Index (RSI) is a movement indicator used in technical analysis. The RSI measures the speed and volatility of recent price changes to assess the uptrend or downtrend conditions.

J. Welles Wilder Jr. introduced this index in his book New Concepts in Technical Analysis in 1978.

The RSI is displayed as a line graph that moves between two extremes, which is called an oscillator. Its reading can range from zero to 100.

The RSI indicator can be used in securities and trading with them. It can also indicate a trend regression or corrective reversal in the security price. Such a trend can provide investors with the signal of buying and selling time. Typically, an RSI reading of 70 or higher indicates a maximum overbought condition. Also, placing the RSI indicator line at 30 or below will show a top-selling situation.

Key points about the RSI indicator

The Relative Strength Index (RSI) is a popular oscillator introduced in 1978.

The RSI indicator provides traders with a signal about bullish and bearish price momentum. It is often plotted below an asset’s price chart.

Usually, when the RSI indicator line is above 70 and below 30, it provides traders with buy or sell signals.

Crossing the RSI line below or above the oversold line is often seen by traders as a buy or sell signal.

The RSI indicator works better in trading ranges rather than in trending markets.

How does the RSI indicator work

As a momentum indicator, the index compares the relative strength of price swings at their lowest and highest levels. Correlating the result of this comparison with the actual price can give traders an idea of an asset’s performance. The RSI indicator and other technical indicators can help traders make better-informed trading decisions.

The RSI indicator ranges from 0 to 100, compared between 30 and 70. These levels can also be adjusted to give better information to the trading round. For example, if an asset repeatedly reaches level 70, you may want to set this level to 80.

Note: During strong trends, the RSI indicator may remain at the overbought and oversold levels for a long time.

In a bull market, the RSI indicator tends to move between 40 and 90. During a downtrend, the RSI indicator tends to be between the 10 and 60 zones. This range will vary depending on RSI settings and the strength of the underlying trend or market.

Suppose the underlying prices confirm a new level that the RSI does not guarantee. In that case, this divergence can signal a price reversal. Suppose the RSI makes a lower level followed by a downward move below the previous level. In that case, a breakout occurs in the uptrend. If the RSI is lower and followed by an up move above the last level, a reversal down breakout has occurred.

RSI calculation

The RSI indicator uses a two-part calculation that begins with the following formula:

RSI = 100−(1+ average profit or loss 100)

The average profit or loss used in this calculation is the average percentage of profit or loss during the return period. This formula uses a positive value for the average loss. Periods with price losses are counted as zero in average profit calculations. Profit periods are also counted as zero in average loss calculations. The standard number of periods used to calculate the initial amount is 14.

RSI chart

After calculating the RSI, the RSI indicator can be plotted below the asset price chart. As the number and size of extended days increase, the value of the RSI also increases. As the number and size of down days increase, the RSI value will fall.

The RSI indicator can stay in the overbought zone for a long time while the stock uptrend. The indicator may also remain in oversold territory for a long time, Where the stock is a downtrend. This can seem confusing to novice analysts, but learning to use the indicator in the context of a prevailing trend will clarify these issues.

Why is it essential to use the RSI indicator in technical analysis

Using the RSI indicator in technical analysis is very important for investors for the following reasons:

Traders can use the RSI indicator to predict the price behavior of an asset.

The RSI indicator can help traders confirm trends and reversals.

RSI can indicate the maximum buy and sell at any given time.

The RSI indicator can provide traders with short-term profitable buy and sell signals.

The RSI indicator is a technical indicator that can be used with others to support trading strategies.

Use RSI with trend

Change the RSI level according to the trends. The primary trend of the asset is significant to correctly and timely understand the movement of the RSI indicator. For example, a well-known financial market analyst, Constance Brown, suggests that a bullish RSI reading is likely to be well above 30. Similarly, the complete breakdown during the downtrend will be much less than 70.

During the downtrend, the RSI indicator is closer to 50 and not 70. Traders see this as a more reliable indication of bearish conditions. Many investors create a horizontal trend between the 30 and 70 levels to analyze the RSI indicator better.

On the other hand, the change in the RSI level may cause a divergence when the stock or asset price is in a long-term horizontal channel or trading range instead of an uptrend or downtrend.

The relative strength indicator in trend markets is not as reliable as trading. Most traders understand that the signals given by the RSI indicator in uptrends or downtrends can often be inaccurate.

Use buy and sell signals that match the trend

A related concept focuses on trading signals and trend-following techniques. In other words, using bullish signals when the price is in an uptrend and bearish signals when the stock is in a downtrend may help traders avoid false alarms from the RSI indicator.

What are maximum purchases and maximum sales

Generally, when the RSI indicator crosses 30, it is a bullish sign; when it crosses 70, it is a bearish sign. In other words, it can be interpreted that RSI values ​​of 70 or higher indicate that the asset is in a maximum overbought state. As a result, this asset may be prioritized for a trend reversal or correction price refund. Conversely, an RSI line of 30 or below indicates an oversold situation.

Overbought occurs when the desired asset is traded at a higher price than the actual value. This means that the price is not where it should be, according to technical or fundamental analysis experts. Traders who see signs of overbought may expect a price correction or trend reversal. Therefore, they may sell their property.
The same idea applies to max selling an asset. In the case of maximum selling, the desired asset is placed in a price range lower than the expected level. Traders who see such a signal may expect a price correction or trend reversal and buy the asset.

Interpretation of RSI and RSI ranges

During the trend, the RSI indicator may enter a range. During an uptrend, the RSI indicator stays above 30 and should often reach 70. During a downtrend, it is less common to see the RSI indicator above 70. This index often reaches 30 or lower.

These guidelines can help traders determine the trend’s strength and potential reversals. For example, if the RSI indicator fails to reach 70 during an uptrend but then falls below 30, the trend is weak and could turn lower.

The opposite is also true for the downward trend. If the downtrend fails to reach the number 30 or below and is seen above the number 70, the downtrend has weakened and can return to the uptrend. Trend lines and moving averages are helpful technical tools that can be used for better analysis when using the RSI.

Difference between RSI and MACD

The MACD indicator is another trend indicator that shows the relationship between two moving price averages. MACD is calculated by subtracting the 26-day moving average from the 12-day EMA. The result will be the calculation of the MACD line.

The 9-day MACD EMA, called the signal line, is drawn above the MACD line. This EMA can act as a trigger for buying and selling signals. Traders may buy an asset when the MACD crosses above its signal line and sell it when the MACD crosses below the signal line.

The RSI indicator is designed to show whether the relevant asset is overbought or oversold concerning current price levels. It is calculated using the average price profit and loss over a given period. The default duration is 14 periods, and its values ​​are limited from 0 to 100.

MACD measures the relationship between two EMAs, while RSI measures the movement of price changes concerning recent highs and lows. As a result, these two indicators often give analysts a complete technical picture of a market.

These indicators both measure the movement of an asset. However, they measure different factors, so they sometimes give conflicting indications. For example, the RSI indicator may stay above 70 for a sustained period, indicating that the asset is in overbought mode. At the same time, the MACD can indicate that buying and selling for the asset is still increasing.
Any indicator may show a trend contradictory to what it is by showing divergence from the price change.

Limits of the RSI indicator

The RSI indicator compares the upward and downward movement of the price. It displays the results on the oscillator placed below the price chart. Like most technical indicators, its signals are reliable when matching long-term trends.

Accurate reversal signals in this indicator are rare and difficult to separate from false alarms. For example, a false positive could be a bullish crossover followed by a sudden drop in the stock. Conversely, a false negative would be a situation with a bearish crossover, but the stock suddenly accelerates higher.

Since this indicator shows the price movement, it can stay at the buy or sell high for a long time. Therefore, RSI will be helpful in a volatile market where the price of an asset alternates between upward and downward movements.

Final word

The RSI indicator was introduced by Wells Wilder and is a momentum oscillator that measures the speed and variability of price movements. The RSI fluctuates between zero and 100. Signals of this indicator can be created by looking for divergence and price fluctuations. RSI can also be used to identify general trends.

Most Common Questions

What does RSI mean?

RSI stands for Relative Strength Index, which measures a stock’s or other asset’s price movement. The main idea behind the RSI is to identify the buy and sell highs and, based on that, give traders buy and sell signals for the asset. The RSI plots this result on a scale of 0 to 100.

When to buy while using the RSI indicator?

If the RSI falls below 30, some traders consider it a buy signal. This is based on the belief that the asset in question has been oversold and will therefore be ready to bounce back. However, the reliability of this signal depends somewhat on the overall trend. For example, suppose the asset is in a significant downtrend. In that case, it may continue to trade at the oversold level for some time. Traders in this situation may delay buying until other technical indicators confirm their buy signal.

When to sell while using the RSI indicator?

Since the relative strength index is mainly used to determine whether an asset is overbought or oversold, an RSI above 70 can mean an asset is overbought and indicates a bearish price. Therefore, it can be considered a signal to sell the asset.
