Relative strength definition: Understanding and Applying Relative Strength Standards


Placing the indicator “behind price” makes it easy to compare the two lines. The chart below shows the Price Relative behind the price plot. Notice the bullish divergence in August and the bearish divergence in December. Use “Advanced Options” to add a moving average or another indicator to the Price Relative.Click here for a live example.

The market is in defensive mode when consumer staples, healthcare and utility sectors lead. Once the leading sectors have been determined, chartists can then look within these sectors to find the leading stocks. Sectors that show relative weakness can be avoided to help narrow the search. As with all indicators, it is important to use the Price Relative in conjunction with other technical analysis tools.

Pros and cons of RSI

In fact, a plot of RS looks exactly the same as a plot of RSI. The normalization step makes it easier to identify extremes because RSI is range-bound. Assuming a 14-period RSI, a zero RSI value means prices moved lower all 14 periods and there were no gains to measure.

However, one can change these levels based on the security situation. For example, if a security’s overbought level of 70 is consistently reached, it can be raised to 80. Very overbought and very oversold periods are defined at 80 and 20 respectively. The rate of change of price action can indicate if momentum is accelerating or decelerating. This is important as it can help traders determine the current trading environment and define which strategy to adopt.

Interpreting RSI ranges

In addition, investors believe that companies with a high RPS will attract other investors to invest in the stock . Relative price strength uses historical data – past performance is not indicative of future performance. Therefore, a stock with a higher RPS compared to another stock does not indicate that the stock is a better pick moving forward.

  • Second, chartists can look for bullish and bearish divergences in relative strength to warn of a potential reversal in the stock price.
  • For example, in the Apple chart, the purple arrow shows a situation where prices hit a new lower low but the RSI does not make a lower low.
  • Finally, Wilder wrote that chart formations and areas of support and resistance could sometimes be more easily seen on the RSI chart as opposed to the price chart.
  • The first three overbought readings foreshadowed consolidations.

The buy triggers form on bounces back up through the 30 band and sell/sell short triggers form when RSI falls back under the 70 band. Strong uptrends can signal multiple bearish divergences before a material reversal may set in and vice versa on strong downtrends. 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 to price action of the underlying security.

RSI example calculation

If a 150-pound CrossFit athlete really wants to clean double body weight and he is only 20 pounds off, then that would show he has solid relative strength. He has good absolute strength, but compared to some of his friends who clean 350 pounds, he is behind in that category. This athlete has been working for a while and he’s just stuck at 280 pounds. His other option is to lose weight, most likely bringing his absolute strength down, but that might make his relative strength go up. The Relative Strength Index is a momentum indicator that measures the magnitude of recent price changes to analyze overbought or oversold conditions.

Again, the higher high is usually just below overbought levels in the area. Chart 12 shows Starbucks forming a lower high as RSI forms a higher high. Even though RSI forged a new high and momentum was strong, the price action failed to confirm as lower high formed.

How to use the RSI indicator?

The Momentum indicator identifies when the price is moving upward or downward and how strongly. Momentum measures the rate of change in prices as opposed to the actual price changes… Another way to use RSI is to look for divergences from price moves, indicating possible weakness in the current trend. It may also signal an impending reversal of the existing trend. Notice how the first dip in the RSI is much lower than the second one, despite the stock’s price actually hitting a lower low.


A sell signal occurs when the RSI rises to an overbought level and then falls back below 70. The more extreme the values, the more “overbought” or “oversold” the currency pair is considered to be. To suggest when a recent price move might be reaching “overbought” and “oversold” levels. In an uptrend or bull market, the RSI tends to remain in the range with the zone acting as support. When the relative strength line is moving up, the active symbol is outperforming the RS symbol and under-performing when the line is moving down.

This discuss the advantages and disadvantages reversal foreshadowed the big support break in late June and sharp decline. According to Wilder, divergences signal a potential reversal point because directional momentum does not confirm price. A bullish divergence occurs when the underlying security makes a lower low and RSI forms a higher low. RSI does not confirm the lower low and this shows strengthening momentum. A bearish divergence forms when the security records a higher high and RSI forms a lower high.

Basil formerly worked as an assistant strength coach at both Bryant University and SUNY Maritime College. He is a certified strength and conditioning specialist and is also certified through USA Weightlifting. Beginners cannot execute to the same degree that advanced trainees do. Conversely, beginner training will not be a sufficient-enough stimulus for advanced populations. It’s your job as the coach to determine what level the group you are working with is currently at and tailor the training accordingly.

This also means that values become more accurate as the calculation period extends. SharpCharts uses at least 250 data points prior to the starting date of any chart when calculating its RSI values. To exactly replicate our RSI numbers, a formula will need at least 250 data points. Relative Strength Comparison compares a security’s price change with that of a “base” security or index. When the Relative Strength Comparison indicator is moving up, it shows that the security’s price is performing better than the base security/index in relative terms. When the indicator is moving sideways, it shows that both securities prices are rising and falling by the same percentages.


However, for the purposes of this blog, we are going to look at the differences between relative strength and absolute strength training. Wilder believed that tops and bottoms are indicated when RSI goes above 70 or drops below 30. Traditionally, RSI readings greater than the 70 level are considered to be in overbought territory, and RSI readings lower than the 30 level are considered to be in oversold territory. In between the 30 and 70 level is considered neutral, with the 50 level a sign of no trend. The RSI provides signals that tell investors to buy when the security or currency is oversold and to sell when it is overbought.

Traders may want to allow the RSI to recapture its 50 line before joining the uptrend. When it comes to identifying opportunities in the stock market, sometimes the simplest solution can be effective. So let’s take a look at using the relative strength indicator to help find potentially profitable stocks. Some traders who use technical analysis can fall prey to the idea that the more complex an indicator is or the more indicators you have on a chart, the better your analysis. With so many indicators to choose from, it’s easy to succumb to that thinking. The indicators no longer retain their logic and can lose some effectiveness.
