Bullish and bearish markets play a big role in how the RSI behaves. During a bull market, RSI values normally sit in the 40 to 90 range, with the range seen as support. In a bear market, the reading typically stays within the 10 to 60 range, with the zone signaling resistance. These ranges are typical but may vary based on the settings for the index, as well as the strength of the underlying market trend for any given security.
In addition to the overbought and oversold indicators mentioned above, traders who use the Relative Strength Index indicator also look for centerline crossovers. Relative Strength Index, or RSI, is a popular indicator developed by a technical analyst named J. Welles Wilder, that helps traders evaluate the strength of the current market.
The stochastic tends to get overbought and oversold more often than the RSI, providing more trading entries but also more false signals. The values of the RSI oscillator, typically measured over a 14-day period, fluctuate between zero and 100. The Relative Strength Index indicates oversold market conditions when below 30 and overbought market conditions when above 70. They look for signals of waning or strengthening momentum in short to intermediate term price movements within a market.
The RSI is displayed as an oscillator on a scale of zero to 100. Welles Wilder Jr. and introduced in his seminal 1978 book, New Concepts in Technical Trading Systems.

A nine-day EMA of the MACD, called the signal line, is then plotted on top of the MACD line. 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. An RSI divergence occurs when price moves in the opposite direction of the RSI. In other words, a chart might display a change in momentum before a corresponding change in price. During an uptrend, the RSI tends to stay above 30 and should frequently hit 70.
What is the difference between RSI and stochastic?
This parameter is set to 14 by default, and this setting is considered optimal in most cases. You can also adjust the style settings, like line colour and weight. By using another tab of configuration window, you can change parameters of the levels from 30 and 70 to 20 and 80.
A bullish failure swing forms when RSI moves below 30 , bounces above 30, pulls back, holds above 30 and then breaks its prior high. It is basically a move to oversold levels and then a higher low above oversold levels. Chart 7 shows Research in Motion with 10-day RSI forming a bullish failure swing.
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 bullish divergence formed with eBay moving to new lows in March and RSI holding above its prior low.
Place a Stop Loss and Take Profit to the nearest key levels or Fibonacci . Sure enough, as RSI passes below 50, it is a good confirmation that a downtrend has actually formed. RSI is a very popular tool because it can also be used to confirm trend formations. A movement from above the centerline to below indicates a falling trend. A movement from below the centerline to above indicates arising trend.
RSI and moving average convergence divergence are both momentum measurements that can help traders understand a security’s recent trading activity. 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. These guidelines can help traders determine trend strength and spot potential reversals.
If the average of U values equals the average of D values, the RS is 1 and RSI is 50. If the average of U values is maximal, so that the average of D values is zero, then the RS value diverges to infinity, while the RSI is 100.

RSI Trading Strategy and MACD
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.
The Money Flow Index is a trading tool that incorporates volume and price data. It can be used to generate trade signals based on overbought and oversold levels as well as divergences. Since the indicator displays momentum, it can stay overbought or oversold for a long time when an asset has significant momentum in either direction.
The only difference will be that instead of levels 30 and 70 we will set it at 50. The main signal the RSI oscillator generates allows defining overbought and oversold price ranges. Although it is frequently used as a filter in systems where the main indicator is a trend one, it might be possible to try trading using RSI signals only. The same caveat applies to extended downtrend price movement that may occur well after an RSI indication of a market being “oversold”. 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.
How to set the RSI indicator?
The indicator may also remain in oversold territory for a long time when the stock is in a downtrend. This can be confusing for new analysts, but learning to use the indicator within the context of the prevailing trend will clarify these issues. To set the RSI indicator, choose the desired timeframe and customise the time periods for calculation . Adjust the settings in line with your trading strategy, which could be using 7 or 10 periods for day trading. 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.
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. This means prices moved higher all 14 periods and there were no losses to measure. The descending triangle is a chart pattern used in technical analysis.
Overbought and oversold conditions
However, RSI does have limitations, including the possibility of producing false signals and not predicting the magnitude of price reversals. Despite these drawbacks, RSI remains a useful indicator for traders seeking to navigate the complexities of financial markets. Those following this RSI trading strategy may consider waiting until the RSI falls below the 70 from an overbought condition level to take a possible short position. Then when the RSI rises above 30 from oversold conditions, the idea is to take a long position.
RSI is a versatile momentum oscillator that has stood the test of time. Despite changes in volatility and the markets over the years, RSI remains as relevant now as it was in Wilder’s days. While Wilder’s original interpretations are useful to understanding the indicator, the work of Brown and Cardwell takes RSI interpretation to a new level. Adjusting to this level takes some rethinking on the part of the traditionally schooled chartists.
Its purpose is to smooth the results so that the RSI only nears 100 or zero in a strongly trending market. 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.
Traditionally, an RSI reading of 70 or above indicates an overbought situation. Stop Loss and Take Profit are fixed and set at distances 20 and 50 points from the opening price respectively. Such ratio enables to obtain a positive statistical expectation from trading in the long run. If RSI swings lower but the price continues higher, this could be a sign of a short-term trend reversal. When divergence occurs, the theory states that there is a higher probability of price reversing.
