RSI measures the speed and magnitude of a security’s recent price changes to evaluate overvalued or undervalued conditions in the price of that security. However, according to the RSI formula, the too-high or too-low value of the indicator indicates that the up or down movement prevailed over a certain period. It can only indicate the strength of a trend but does not necessarily indicate that a price change is imminent. The real stable variation of the indicator values is better to determine statistically.
A positive divergence indicates a short-term boost in the assets price. In contrast, a negative one implies a short-term fall in the security’s value. Once selected, users can place the indicator above, below or behind the underlying price plot. Placing RSI directly on top of the price plot accentuates the movements relative What Does Volume Mean When Trading Stocks to price action of the underlying security. Users can apply “advanced options” to smooth the indicator with a moving average or add a horizontal line to mark overbought or oversold levels. If the asset is uptrending and the market is bullish, the RSI usually ranges from 40 to 90, where the zone acts as a support line.
The Relative Strength Index, or RSI, is used to locate overbought and oversold conditions in financial markets. Typically any reading above 70 is considered overbought and ripe for a reversal, while readings below 30 are considered oversold and also ripe for a reversal. The MACD indicator is very popular because of its simplicity and ease of application, as well as its graphical appeal.
How to Calculate and Understand RSI
This tool is often used in conjunction with RSI to give traders more data to understand what the future holds for a stock or an entire market. To sum up, the RSI measures the speed of an asset’s price changes and is used in technical analysis as a momentum indicator. As a result, it can be a powerful tool for determining trend reversals. The RSI is displayed as an oscillator and can have a reading of 0 to 100. Momentum indicators are generally considered to be technical tools to measure the speed or velocity of market price movements. Because the RSI is typically used to detect overbought and oversold markets some traders feel it can’t be used in a trending market, but nothing could be further from the truth.
Moreover, short-term trading setups may adjust the RSI indicator to consider 20 and 80 as oversold and overbought levels , so it is less likely to provide false signals. A momentum indicator is a useful tool for traders and analysts that assists them to determine the points where the market can or will have alternations. It measures the short-term movements of the price as well as the general trends. To provide security from those price fluctuations, a momentum indicator generates either an RSI “overbought” or an RSI “oversold” signal. Those signals are used by specialists to examine the market’s behavior.
- The pink line is the RSI line, and the 2 horizontal lines are the overbought and oversold areas.
- Finally, Cardwell discovered the existence of positive and negative reversals in the RSI.
- The RSI was designed to indicate whether a security is overbought or oversold in relation to recent price levels.
- The RSI may stay in the overbought or oversold territory during strong moves.
- Technical analysts believe oversold assets are those that reach a certain level on a technical indicator, focusing on price and historical data rather than the asset’s value.
One RSI trading strategy used in trending markets would be to wait for the indicator to signal an overbought condition during an uptrend.

How we make money
If the indicator’s line crosses the level 30 from below, a long position is opened. So now you have learnt what the RSI is, how to use it and how to put it in a script and generate signals from it. To understand how divergence works, imagine you are climbing a hill. If you are walking up the hill and the slope becomes more gentle, it could mean that you will soon reach the top and then begin to descend. But while you keep going uphill with each step , your elevation gain will be smaller with each step .
The relative strength index was introduced in 1978 by technical analyst J. Welles Wilder Jr. in his bookNew Concepts in Technical fxchoice review Trading Systems. The offers that appear in this table are from partnerships from which Investopedia receives compensation.
Divergences can be rare when an asset is in a steady long-term trend. So, utilizing oversold or overbought readings will help determine additional signals. In other words, it is essential to wait until the RSI crosses back under 70 or back above 30. Technical analysis focuses on market action — specifically, volume and price.

The zone subsequently marked resistance until a breakout in December. A bearish failure swing forms when RSI moves above 70, pulls back, bounces, fails to exceed 70 and then breaks its prior low. It is basically a move to overbought levels, followed by a lower high beneath those levels.
RSI and Chart Patterns
These principles help them understand how an asset or market is performing so that an educated investment can be made. One such tool is the Relative Strength Index, otherwise known as RSI. While much has changed in investing due to technological disruption, RSI has been around since well before anyone could trade on their smartphones — or since anyone even had a smartphone.
The slope of the RSI is directly proportional to the velocity of a change in the trend. The distance traveled by the RSI is proportional to the magnitude of the move. Wilder posited that when price moves up very rapidly, at some Saxo Bank Forex Broker Overview point it is considered overbought. Likewise, when price falls very rapidly, at some point it is considered oversold. A stochastic oscillator is used by technical analysts to gauge momentum based on an asset’s price history.
How is the RSI calculated? RSI Indicator Calculation & Formula
The range from 70 to 100 is an overbought zone, while 0 to 30 is an oversold zone. When the RSI indicator reaches the first range, a price decline is expected. The option of staying in the corridor from 0 to 30 signals further price growth.

Exiting an open trade should be done when RSI enters the opposite zone. Sometimes, an opposite position can be opened simultaneously with closing previous position, granting other signals to follow the aforementioned pattern. This article will explain what the RSI indicator is and how it works.
You can use RSI for any time period, but the most commonly used window includes the previous 14 days of market activity. So, you would add up all the gains over the period and divide by 14 for your average gains. Then, you add up all the losses and divide by 14 to calculate your average losses. In addition to the basic 70/80 or 30/20 readings, traders also watch for divergence between price movement and the value of the RSI. When price hits a new low or high that isn’t supported by a corresponding new low or high in the RSI reading, this can indicate an impending price reversal in the market. The Relative Strength Index is one of the most popular and widely used momentum oscillators.
Moreover, when an asset is oversold or its price is undervalued, then the RSI value falls under 30. 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. Taking the prior value plus the current value is a smoothing technique similar to that used in calculating an exponential moving average.
Using RSI With Trends
This suggests that, despite the price drop, the buying pressure is increasing. Conversely, a bearish divergence would indicate that the selling pressure is increasing, despite an increase in market price. Traders use the RSI to spot potential overbought and oversold market conditions.
