What Is Relative Strength Index (RSI)?

The Index is a popular price momentum oscillator developed by J. Welles Wilder and introduced in his 1978 book New Concepts in Technical Trading Systems. The RSI oscillates in a range between 0 and 100 representing a comparison of the magnitude of a stock’s recent gains to the magnitude of its recent losses. RSI usually stays in the range of during an upward or bull market. Conversely, it remains in the range of during a downward or bear market, with resistance in the range of 50 to 60.

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.

What Does RSI Mean?

The relative strength index (RSI) measures 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 100.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.

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.

What is RSI?

As with any technical analysis​ study, the RSI can be used in conjunction with other tools, including the 200-day moving average​. In the above chart, Apple shares consolidated around the 200-day moving average in February. There is generally no RSI formula that can be relied on to determine when the rebound will occur. This means that prices could remain below 20 for months before experiencing a rebound. The RSI indicator generates a measurement between zero and 100. According to Wilder, the RSI is overbought when the index has a reading above 70, and it is oversold when it has a reading below 30.

In the chart above, the RSI broke down through the trendline​​ support. When the RSI moved higher back to the trend line, it offered an opportunity to short sell Apple shares. The crossover strategy is one way of using the RSI as an overbought indicator in conjunction with decelerating positive or negative momentum. One would purchase Apple shares after the RSI crosses above the 30-trigger level, following an oversold reading. A sell signal is generated when the RSI declines from overbought territory below the 70-overbought trigger level.

Short-term traders sometimes use 2-period RSI to look for overbought readings above 80 and oversold readings below 20. The standard number of periods used to calculate the initial RSI value is 14. For example, imagine the market closed higher seven out of the past 14 days with an average gain of 1%. The remaining seven days all closed lower with an average loss of −0.8%.

In addition to overbought and oversold levels, the RSI can also introduce signals by looking for divergence, failure swings and centreline crossovers. Market prices continue to move higher/lower while the RSI fails to move higher/lower during the same time period. Divergences may occur in a few trading intervals, but true range divergence usually requires a lengthy time frame, perhaps as much as 20 to 60 WAVES trading intervals.

In the RSI indicator, to smoothen the price movement, we take an average of the gains for a certain period.While we call it an average, a little explanation would be needed. For the first 14 periods, it is a simple average of the values. Shares of Schneider Electric, trading as BGSF, hit oversold territory on June 21, 2022, after falling to a price of $120.06 per share, as indicated by an RSI reading of 29.6.

These guidelines can help traders determine trend strength and spot potential reversals. For example, if the RSI can’t reach 70 on a number of consecutive price swings during an uptrend, but then drops below 30, the trend has weakened and could be reversing lower. The RSI can do more than point to overbought and oversold securities. It can also indicate securities that may be primed for a trend reversal or corrective pullback in price. Traditionally, an RSI reading of 70 or above indicates an overbought situation.
