Traders interested in day trading and swing trading can consider shorter periods to calculate the RSI. The Relative Strength Index is one of the more popular momentum indicators and it’s probably among the easiest to use. It measures the overbought or oversold levels on a scale of 1 to 100. This means it tracks the last 14 periods, whether those periods are days or 5-minute bars on a chart. Andrew Cardwell developed positive and negative reversals for RSI, which are the opposite of bearish and bullish divergences.
The RSI oscillator is typically plotted beneath an asset’s price chart. An asset that is oversold is trading at a lower price than you would expect based on other measures of its value. Often, that means the price could increase in the future, but that doesn’t always occur right away or at all. The Relative Strength Index and other tools can help investors identify oversold stocks based on stock price behavior. An RSI value of 30 or below can signify that a stock is oversold. There’s no single definition of the term, so different analysts may come to different conclusions about whether a stock is oversold.
The chart above shows the price of Apple shares along with the RSI in the upper panel for the six months ending 5 March 2018. Apple’s share price was overbought once in early November 2017, according to the RSI. The RSI reached a high of Finance 76 in November 2017 and a low of 17 in February 2018. Then you would calculate the sum of the loss over the past 14 days and divide this figure by 14. It provides important information that traders can use prior to entering a position.
Positive and negative reversals put price action of the underlying security first and the indicator second, which is the way it should be. Bearish and bullish divergences place the indicator first and price action second. By putting more emphasis on price action, the concept of positive and negative reversals challenges our thinking towards momentum oscillators. RSI can be used to construct many different trend trading strategies. One strategy is buying / selling on divergences at extreme RSI values which indicates overbought / oversold levels.
Comparing the RSI chart to price trends can provide investors with more information than RSI alone. The basic rule of thumb is that an RSI value over 70 indicates a stock is “overbought” and may see its price fall in the future. Meanwhile, an RSI value of 30 or lower can mean that the price could go up. An RSI of 50 is often seen as neutral, meaning the stock has not been either overbought or oversold.
The Formula For The Rsi
This scan reveals stocks that are in an uptrend with oversold RSI. First, stocks must be above their 200-day moving average to be in an overall uptrend. In other words, despite stronger momentum as seen by the higher high or lower low in the RSI, price could not make a higher high or lower low.
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. 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. During trends, the RSI readings may fall into a band or range. During an uptrend, the RSI tends to stay above 30 and should frequently hit 70.
Wilder believed that tops and bottoms are indicated when RSI goes above 70 or drops below 30. In between the 30 and 70 level is considered neutral, with the 50 level a sign of no trend.

Investors use the indicator on a stock that has been making sharp up or down moves in a short period and want to know from that technical analysis whether to buy or sell. Popular instruments and commodities to track via relative strength index include bitcoin, gold, and silver.
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 Exchange rate 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.
The percentage of RSIs of different periods being overbought/oversold is additionally used to return adaptive overbought/oversold levels. 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. This scan reveals stocks that are in a downtrend with overbought RSI turning down. First, stocks must be below their 200-day moving average to be in an overall downtrend.

In a bearish divergence, the price of an asset rises while the RSI drops lower. This reflects that the asset’s price increase is beginning to lose upwards momentum. In a bullish divergence, the RSI gets higher while an asset’s price continues to drop. This reflects that there are more people buying the asset despite the price decreasing. In other words, if the stock is trending at 30 or lower, the indicator suggests a reversal for the price to go higher.
During a downtrend, it is rare to see the RSI exceed 70, and the indicator frequently hits 30 or below. These guidelines can help 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. A related concept to using overbought or oversold levels appropriate to the trend is to focus on trade signals and techniques that conform to the trend.
