The default time period is 14 periods, with values bounded from 0 to 100. 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.

He started trading stocks around 1972 but wasn’t very successful. A few years later, Wilder compiled his trading research and experience into mathematical formulas and indicators that were later adopted by many traders around the world. The book was produced in only six months, and despite dating back to the 1970s, it is still a reference to many chartists and traders today. Some traders use more extreme RSI values of 20 for buying and 80 for selling to play it “safe” with more volatile assets.

As such, they can be used to trade RSI divergences by identifying recent trends in order to spot the signs of trend reversals. Divergence is a term used by technical analysts to describe signals of prices that move in the opposite direction from a technical indicator. Divergence can be either positive or negative, where positive ones indicate that an asset’s price hits a new low as the indicator’s value climbs.

Calculation

Cardwell’s books are out of print, but he does offer seminars detailing these methods. Before discussing the reversal technique, it should be noted that Cardwell’s interpretation of divergences differs from Wilder. Cardwell considered bearish divergences to be bull market phenomena – in other words, bearish divergences are more likely to form in uptrends.

The RSI compares bullish and bearish price momentum and displays the results in an oscillator placed beneath a price chart. Like most technical indicators, its signals are most reliable when they conform to the long-term trend. 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. One RSI trading strategy used in trending markets would be to wait for the indicator to signal an overbought condition during an uptrend. The trader then waits for RSI to drop below 50, which signals a long entry.

This helps traders identify assets that are potentially overbought – meaning they are trading above their true value – or oversold, meaning they are trading below their true value. Welles Wilder Jr. suggested collecting data from the past 14 trading periods . To this day, it is one of the most popular tools among traders. But other trade signals can help traders when overbought and oversold asset prices don’t change course right away. For instance, the moving average convergence divergence and moving average crossovers both allow traders to verify RSI indicators. The MACD indicator is very popular because of its simplicity and ease of application, as well as its graphical appeal.

It’s necessary to underline that it is crucial to examine the behavior of the RSI during a trend. When there is an uptrend RSI indicator moves in an area over the value of 30 and most often it reaches 70. However, when there is a downtrend it moves within a different area with its value to be ofttimes below 30 and very rarely reaching 70. With those indications, it’s possible to monitor the direction of the market trend.

What causes stock prices to change?

Generally, when the RSI indicator crosses 30 on the RSI chart, it is a bullish sign and when it crosses 70, it is a bearish sign. Put another way, one can interpret that RSI values of 70 or above indicate that a security is becoming overbought or overvalued. It may be primed for a trendreversalor corrective pricepullback. An RSI reading of 30 or below indicates an oversold or undervalued condition. As any other oscillator, the RSI indicator is not plotted on the price chart, but in a separate window below.

Therefore, RSI thrives in choppy or oscillating trading markets or markets without strong trends, in contrast to moving averages. Such an approach is based on the so-called bullish and bearish divergences. 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.

Positive divergence occurs when the value of the price reaches higher lows than the RSI indicator’s lows. On the other hand, when a price’s highs are higher than the index’s highs then we speak about a negative divergence.

A nine-day EMA of the MACD called the “signal line” is then plotted on top of the MACD line, which can function as a trigger for buy and sell signals. Traders may buy the security when the MACD crosses above its signal line and sell or short the security when the MACD crosses below the signal line. After the RSI is calculated, the RSI indicator can be plotted beneath an asset’s price chart, as shown below. Once there are 14 periods of data available, the second calculation can be done. Its purpose is to smooth the results so that the RSI only nears 100 or zero in a strongly trending market.
