Divergence is a tool used to spot potential reversals by comparing the movement between indicator and market direction. The charts below illustrate positive bullish reversal and negative bearish reversal divergence signals. RSI measures the relative strength of the market, making this oscillator an invaluable tool that can be employed in virtually any market.
The multiple ways of utilising the RSI allows for traders to become flexible within their trading strategy. Every novice technical trader should definitely have the RSI incorporated into their repertoire.

The opposite is true for a downtrend. If the downtrend is unable to reach 30 or below and then rallies above 70, that downtrend has weakened and could be reversing to the upside.
Trend lines and moving averages are helpful tools to include when using the RSI in this way. A bullish divergence occurs when the RSI creates an oversold reading followed by a higher low that matches correspondingly lower lows in the price. This indicates rising bullish momentum, and a break above oversold territory could be used to trigger a new long position. A bearish divergence occurs when the RSI creates an overbought reading followed by a lower high that matches corresponding higher highs on the price.
As you can see in the following chart, a bullish divergence was identified when the RSI formed higher lows as the price formed lower lows. This was a valid signal, but divergences can be rare when a stock is in a stable long-term trend.
Using flexible oversold or overbought readings will help identify more potential signals. Using the RSI in this way is very similar to drawing trend lines on a price chart. Like divergences, there is a bearish version of the swing rejection signal that looks like a mirror image of the bullish version. A bearish swing rejection also has four parts:. The following chart illustrates the bearish swing rejection signal.
As with most trading techniques, this signal will be most reliable when it conforms to the prevailing long-term trend. Bearish signals during downward trends are less likely to generate false alarms. The result of that calculation is the MACD line. The RSI was designed to indicate whether a security is overbought or oversold in relation to recent price levels. The RSI is calculated using average price gains and losses over a given period of time.
The default time period is 14 periods, with values bounded from 0 to These two indicators are often used together to provide analysts with a more complete technical picture of a market. These indicators both measure the momentum of an asset.
However, they measure different factors, so they sometimes give contradictory indications. For example, the RSI may show a reading above 70 for a sustained period of time, indicating the security is overextended to the buy side.
At the same time, the MACD could indicate that buying momentum is still increasing for the security. Either indicator may signal an upcoming trend change by showing divergence from price the price continues higher while the indicator turns lower, or vice versa. The RSI compares bullish and bearish price momentum and displays the results in an oscillator that can be placed beneath a price chart.
Like most technical indicators, its signals are most reliable when they conform to the long-term trend. True reversal signals are rare and can be difficult to separate from false alarms. A false positive, for example, would be a bullish crossover followed by a sudden decline in a stock. A false negative would be a situation where there is a bearish crossover, yet the stock suddenly accelerated upward. Since the indicator displays momentum, it can stay overbought or oversold for a long time when an asset has significant momentum in either direction.
Therefore, the RSI is most useful in an oscillating market where the asset price is alternating between bullish and bearish movements. The Relative Strength Index RSI is a measurement used by traders to assess the price momentum of a stock or other security. The basic idea behind the RSI is to measure how quickly traders are bidding the price of the security up or down. The RSI plots this result on a scale of 0 to Readings below 30 generally indicate that the stock is oversold, while readings above 70 indicate that it is overbought.
Traders will often place this RSI chart below the price chart for the security, so they can compare its recent momentum against its market price. However, the reliability of this signal will depend in part on the overall context.
If the security is caught in a significant downtrend, then it might continue trading at an oversold level for quite some time. Traders in that situation might delay buying until they see other confirmatory signals. Traders can then base their buy and sell decisions on whether the short-term trend line rises above or below the medium-term trend line. Welles Wilder, Jr. Trend Research, Constance M.

Like most oscillators, an RSI can be used to warn of pending reversals or retracements. If the price makes a higher high, while the RSI makes a lower high, a bearish reversal or retracement might be developing. If the price makes a lower low but the RSI makes a higher low, prices may soon rise.
Divergence does not indicate exactly when the move will occur, or its magnitude. Price action needs to be watched carefully for confirmation. Trend lines can also be drawn on the RSI indicator, with a break of the trend line indicating a change in the direction of momentum. Trend lines on the RSI and price chart can also be combined.
If trend lines on both the RSI and price are broken there is a higher probability of the price following through, than if only one is broken. Scalpers and short-term counter-trend traders often use a 2-period RSI to identify extreme price moves. They will usually use more extreme levels like 90 or 95 for overbought and 10 or 5 for oversold.
Trades are then entered in the opposite direction of the move. Positions are exited once the RSI crosses above or below 50, or when the price reaches the midpoint of the trading range. Extreme moves can also persist for some time. As you can see, the RSI is a very versatile indicator. It can be used for so many purposes, including replacing several other indicators, leading to an uncluttered chart layout.
However, it should not be used in isolation and is best used with moving averages, trend lines, or a MACD indicator. All expressions of opinion are subject to change without notice.

The standard setting is 14 periods, but traders often adjust this to anywhere from 2 to 25 depending on how they want to use it. The theory behind the RSI is that buyers and sellers can usually only push the market in one direction for so long. Eventually, the price momentum will run out and the market will have to move in the opposite direction…at least for a little while.
That's when countertrend traders can potentially step in and make some money with the RSI indicator. So we created a graphic that clears up the confusion and shows you exactly how the RSI calculation formula works. It's basically the number of periods that you want to look back on the chart to determine the current RSI value. Many websites refer to the default RSI setting as 14 days , but that's only if you are trading on the daily chart.
The RSI look back can also be measured in weeks, hours or minutes. Your RSI period setting will depend on your goals and your trading strategy. There's no right or wrong answer here. It just depends on what you have tested and what is profitable for you. You will learn more about how the RSI settings affect the characteristics of a RSI trading strategy in parts 2 and 3 of this series. The raw Relative Strength number simply shows you how current price compares to historical prices over the last n periods.
It can be a little tough to understand what that number is actually telling you. So Wilder's formula turns the number into an index that stays between zero and Therefore, the RSI is an oscillator because it goes back and forth on a fixed scale between 0 and Having a set scale allows RSI to be easily used across any trading instrument.
It's also a momentum indicator because its goal is to show traders when momentum could be slowing down. The first RSI graph point is calculated by summing the up periods and dividing the result by the n periods setting in the RSI indicator. For example, let's say that you are trading the daily chart and n is set to 5. The last 5 days are as follows:. After the first RSI data point, all of the following data points are calculated with this modified formula.
This formula is similar to an exponential or weighted moving average, in that it gives more weight importance to the current RS reading. So you would start by averaging the first n -1 periods for both up and down moves. Then you would add in the current average for up and down moves to their respective averages and divide each total by n. Let's use the data from the previous example and add in a 6th period, to show you how this works.
Next, average the data from the previous 5 periods, plus the 6th period. Since the 6th period is a down period, nothing would be added to the up periods calculation. As mentioned above, the default signal levels are usually 30 and But some traders will use 20 and If the RSI is over 70, price is considered overbought and is a potential sell signal.
If the RSI goes below 30, that's a potential buy. We will get into RSI trading strategy details in part 2 of this series, but that's the general concept of what the RSI tells you. A shorter look back period will make the RSI more sensitive, which can work well for certain trading strategies. A longer period may work better for other strategies. Test your strategy with different RSI settings and find out what really works for you.
