Another price-RSI relationship that traders look for is positive and negative RSI reversals. Positive and negative reversals are the opposite of bearish and bullish divergences. On the other hand, oversold defines a period with a substantial and consistent downward move in price over time without much pullback. The term refers to a condition where a security has traded well below its typical value metrics and has the potential for a price bounce. Similarly, oversold conditions may indicate a price correction or trend reversal and signal traders to enter (buy) a position.
An alert set on one of these Diversion conditions will only fire if this setting is turned on. An RSI between 30 and 70 was to be considered neutral and an RSI around 50 signified “no trend”.

How to use RSI indicator?
- With the RSI, which oscillates between 0 and 100, 70 is considered the default overbought threshold and 30 the oversold threshold.
- An RSI of 70 indicates that the asset is overbought, suggesting it might be due for a price pullback.
- For instance, an RSI oversold reading gains credibility when followed by a MACD bullish crossover.
- Trading in digital assets, including cryptocurrencies, is especially risky and is only for individuals with a high risk tolerance and the financial ability to sustain losses.
- There are three basic components in the RSI—RS, Average Gain, and Average Loss.
- The moving average convergence divergence (MACD) is another trend-following momentum indicator that shows the relationship between two moving averages of a security’s price.
Market participants use these signals as warnings, as they often precede price retracements. The Relative Strength Index, or RSI, is a momentum oscillator that measures the speed and change of price movements. Welles Wilder Jr, the RSI was introduced in his book New Concepts in Technical Trading Systems in 1978. The Relative Strength Index (RSI) is a popular and powerful tool used by traders for technical analysis. Even with many new indicators available, the RSI stands out because it’s simple to use, has been around for a long time and works well. In this guide, we’ll explain what RSI is and the best way to interpret and use it.

As a momentum indicator, the relative strength index (RSI) compares a security’s strength on days when prices go up to its strength on days when prices go down. Relating the result of this comparison to price action can give traders an idea of how a security may perform. The RSI, especially when used in conjunction with other technical indicators, can help traders make better-informed trading decisions. The RSI focuses on momentum and is particularly effective in identifying overbought and oversold conditions. It complements other technical indicators, such as moving averages and MACD, which provide different types of information. This question could refer to the time frame used in an RSI calculation.
Overall, the RSI indicator is a valuable tool for traders seeking to analyze market momentum and spot potential trading opportunities. However, it’s crucial to remember that RSI should not be used alone and should be combined with other forms of analysis for more informed decision-making. For instance, in a very volatile market, you might raise the overbought level to 80 or 90 to stay in trades longer. In a calmer market, you could lower the oversold level to 20 or 10 to spot potential reversals sooner. A common mistake traders make is to buy or sell immediately when the RSI enters an overbought or oversold territory.
This means prices moved higher in all 14 periods, and there were no losses to measure. Traders can then base their buy and sell decisions on whether the short-term trendline rises above or below the medium-term trendline. As the RSI is mainly used to determine whether a security is overbought or oversold, a high RSI reading can mean that a security is overbought and the price may drop.
There are set number ranges within RSI that Wilder consider useful and noteworthy in this regard. According to Wilder, any number above 70 should be considered overbought and any number below 30 should be considered oversold. We use cutting-edge AI models to forecast future prices for stocks and crypto. Using the RSI in this particular way is very similar to drawing trend lines on a price chart. Divergences occur when the price moves in the opposite direction of the RSI, i.e., a chart might indicate a change in momentum before a corresponding price change. Fortunately, the charting packages on most trading platforms perform these calculations automatically so you don’t have to.
A better approach is to wait until the RSI crosses back below 70, indicating a potential shift in momentum from buyers to sellers. This scan reveals stocks that are in a downtrend with overbought RSI turning down. First, stocks must be below their 200-day moving average to be in an overall downtrend. First, stocks must be above their 200-day moving average to be in an overall uptrend. A bearish failure swing forms when RSI moves above 70, pulls back, bounces, fails to exceed 70, and then breaks its prior low.
The RSI is not as reliable in trending markets as in trading ranges. In fact, most traders accept that the signals given by the RSI in strong upward or downward trends often can be false. Like many momentum oscillators, overbought and oversold readings for RSI work best when prices move sideways within a range. Chart 4 shows MEMC Electronics (WFR) trading between 13.5 and 21 from April to September 2009. The stock peaked soon after RSI reached 70 and bottomed soon after the stock reached 30. RSI and moving average convergence divergence (MACD) are both momentum measurements that can help traders understand a security’s recent trading activity.
The subsequent breakdown in mid-October confirmed weakening momentum. In a bearish divergence, for example, price makes a higher high but the RSI makes a lower high. With a negative reversal, on the other hand, the RSI makes a higher high, while price makes a lower high. However, they measure different factors and may sometimes give contradictory indications.
The strength or weakness is based on closing prices over the duration of a specified trading period creating a reliable metric of price and momentum changes. Overbought describes a period with a significant and consistent upward movement in price over time without much pullback. Overbought conditions may indicate a price correction or trend reversal and signal traders to exit (sell) a position.
Traders’ use of the RSI has evolved over time, including by adjusting timeframes and thresholds to improve accuracy for particular markets. Moreover, algorithmic trading and quantitative finance have incorporated RSI into automated strategies, with variations like Stochastic RSI enhancing its adaptability. Wilder believed that Bearish Divergence creates a selling opportunity while Bullish Divergence creates a buying opportunity.
Using RSI With Trends
An oversold RSI paired with price touching a lower Bollinger Band or a key support level adds confidence to a potential rebound. Likewise, an RSI breakout supported by high volume confirms strong market participation. Unlike with trending markets, when price is rangebound traders can buy near support when the RSI is below 30 and sell near resistance when it is above 70. To improve accuracy, traders should confirm price alignment with support or resistance and use tight stop-losses in case the range breaks.
Interpreting RSI Values
- For a positive divergence, we look at the lows of both the price and the indicator.
- A positive reversal forms when RSI forges a lower low, and the security forms a higher low.
- Divergences tend to be more robust when they form after an overbought or oversold reading.
- Out of those 14 candles, 12 were bullish and only 2 were bearish which resulted in an RSI of 83.
RSI does not confirm the new high and this shows weakening momentum. RSI is a popular momentum indicator that has been featured in a number of articles, interviews, and books over the years. In particular, Constance Brown’s book, Technical Analysis for the Trading Professional, features the concept of bull and bear market ranges for RSI. Andrew Cardwell, Brown’s RSI mentor, introduced positive and negative reversals for RSI and turned the notion of divergence, literally and figuratively, on its head.
Traders often focus on RSI buy signals in an uptrend and sell signals in a downtrend. This alignment with broader trends improves trade accuracy and reduces false signals. Conversely, in downtrends, the RSI usually remains under 60, with oversold levels below 30 occurring more often. Instead of expecting an immediate rebound, many traders look for rallies toward 50 to 60 as potential selling opportunities, treating RSI as a dynamic resistance level. Failure swings are another occurrence which Wilder believed increased the likelihood of a price reversal.
