The Stochastic RSI (Relative Strength Index) was developed by Tushar Chande, a well-known technical analyst who authored books such as “Beyond Technical Analysis” and “The New Technical Trader” and created other popular indicators such as the Chande Momentum Oscillator and the Aroon Indicator. Chande and Stanley Kroll first introduced the Stochastic RSI in 1994 in a technical analysis publication. Since then, it has gained popularity among traders and is commonly used in technical analysis.

The Stochastic RSI is an oscillator that measures the momentum of a financial asset, such as a stock or a currency pair. It determines the ratio of the asset’s current price to its price range during a specified period. The Stochastic RSI combines two widely used indicators: the Stochastic Oscillator and the Relative Strength Index. The former compares the asset’s closing price to its price range during a specified period, while the latter measures the strength of an asset’s price action over a specific time period.

By merging these two indicators, the Stochastic RSI aims to provide traders with more reliable and accurate signals. Instead of using the asset’s price, the Stochastic Oscillator formula is applied to the Relative Strength Index values to calculate it. The resulting oscillator ranges from 0 to 100 and is employed to identify overbought and oversold conditions.

The Stochastic RSI is often used by traders to identify potential trend reversals or confirm the strength of a trend. When the Stochastic RSI reaches overbought or oversold levels, it may indicate a potential reversal in the asset’s price direction. Traders may also use the Stochastic RSI to identify divergences between the indicator and the asset’s price, which can signal a potential change in trend.

Despite its popularity, the Stochastic RSI is not a foolproof tool and should be used in conjunction with other analysis methods to make informed trading decisions.

Computing the Stochastic RSI Oscillator

The Stochastic RSI is calculated by first calculating the traditional RSI for a given period of time (usually 14 days) using the following formula:

RSI = 100 - (100 / (1 + RS))

Where RS is the average of x days’ up closes divided by the average of x days’ down closes.

Next, the Stochastic RSI is calculated by applying the Stochastic Oscillator formula to the RSI values instead of price values. The Stochastic Oscillator measures the momentum of the RSI indicator over a specified period of time and is calculated using the following formula:

%K = (RSI - Lowest RSI Low) / (Highest RSI High - Lowest RSI Low) * 100

Where the highest RSI high is the highest RSI value over the specified period of time, and the lowest RSI low is the lowest RSI value over the specified period of time. %K is the raw value of the Stochastic RSI.

The Stochastic RSI is often displayed as two lines: %K and %D. %D is a moving average of %K and is calculated using the following formula:

%D = 100 * (Sum of %K values over y periods) / y

Where y is the number of periods used to calculate the moving average.

Traders rely on the Stochastic RSI to detect overbought and oversold levels, along with possible trend reversals. Overbought is recognized when the Stochastic RSI surpasses 80, while oversold is indicated when it falls below 20. Divergences between the Stochastic RSI and price action may also provide insights into potential trend reversals.

However, traders should bear in mind that the Stochastic RSI is not a standalone solution and should be utilized alongside other technical indicators and analysis approaches to ensure informed trading decisions.

Interpreting the Stochastic RSI Oscillator

The Stochastic RSI is a crucial tool in technical analysis as it fuses two highly regarded indicators, the Relative Strength Index (RSI) and the Stochastic Oscillator, to provide traders with a comprehensive outlook on an asset’s momentum and potential overbought or oversold conditions. This powerful tool can be utilized for identifying trend reversals, verifying trend strength, and producing trade signals.

A significant advantage of the Stochastic RSI over individual RSI and Stochastic Oscillator indicators is its ability to minimize false signals. By merging two distinct indicators with different calculation methodologies, the Stochastic RSI can filter out market noise and produce more dependable signals.

Furthermore, the Stochastic RSI is a versatile indicator that can be applied to various time frames, asset classes, and trading styles. It can be used for day trading, swing trading, and long-term investing. Moreover, traders can adjust the Stochastic RSI’s settings to make it more or less sensitive to price movements based on their trading objectives.

In conclusion, the Stochastic RSI is a critical technical analysis tool that can facilitate informed trading decisions and enhance profitability in the market.

Tushar Chande’s suggestions on how to use the Stochastic RSI Oscillator

Tushar Chande has shared his insights on how traders can constructively use the Stochastic RSI to improve their trading strategy. Here are some of his tips:

Use the Stochastic RSI in trending markets

The Stochastic RSI works best when there is a clear trend in the asset’s price movement. Traders should avoid using it in flat or range-bound markets, where signals may not be as reliable.

Look for divergences

Traders should watch out for divergences between the Stochastic RSI and the asset’s price to identify potential trend reversals. A bearish divergence may be indicated when the asset’s price makes a new high, but the Stochastic RSI doesn’t follow suit.

Use multiple timeframes

Chande recommends using the Stochastic RSI on different timeframes to get a better understanding of the asset’s momentum. Traders can use a longer timeframe to identify the overall trend and a shorter one to enter and exit trades.

Use the Stochastic RSI with other indicators

The Stochastic RSI is a useful tool but should be used with other technical indicators to confirm signals. Traders can use moving averages or trend lines, for example, to confirm a Stochastic RSI signal.

Wait for confirmation signals

Traders should wait for confirmation signals before entering or exiting a trade based on the Stochastic RSI. For instance, if the Stochastic RSI indicates an oversold asset, traders should wait for the price to start rising before entering a long position.

Adjust the settings

Traders should experiment with different settings to find the optimal ones for their trading style and the asset they are trading. They can adjust the time period, smoothing factor, and overbought and oversold levels to make the indicator more or less sensitive to price movements.

Avoid trading in flat markets

The Stochastic RSI works best in trending markets, so traders should avoid using it in flat or range-bound markets. In such conditions, the Stochastic RSI may produce false signals and result in losses.

Consider market context

Traders should take into account the broader market context when using the Stochastic RSI. Significant news or economic data that could affect the asset’s price may lessen the reliability of Stochastic RSI signals. It is also important to consider the asset’s historical volatility and average trading range when interpreting Stochastic RSI signals.

Use with risk management

Traders should always use proper risk management techniques when using the Stochastic RSI, and should avoid risking more than they can afford to lose on any given trade. Chande suggests using stop-loss orders to limit potential losses and taking profits at predetermined levels.

Overall, Chande sees the Stochastic RSI as a valuable tool but emphasizes that it should be used with other technical indicators and proper risk management techniques to make informed trading decisions.

Advantages & Limitations of the Stochastic RSI Oscillator

Here are some advantages and limitations of using the Stochastic RSI in trading:


  • The Stochastic RSI provides a more comprehensive view of momentum, combining two popular indicators to help traders identify potential trend reversals or confirm trend strength.
  • It is less prone to false signals than either the RSI or the Stochastic Oscillator used in isolation, filtering out noise and providing more reliable signals.
  • The Stochastic RSI is versatile and can be applied to different asset classes, time frames, and trading styles.
  • Traders can adjust the Stochastic RSI’s settings to make it more or less sensitive to price movements, depending on their trading goals.


  • The Stochastic RSI is a lagging indicator and may not provide signals until after a trend has already started, resulting in missed opportunities or late entries.
  • Traders who rely too heavily on technical indicators like the Stochastic RSI may overlook other important factors that can influence market movements, such as news events or economic data.
  • The Stochastic RSI can produce whipsaw signals in choppy or sideways markets, resulting in losses or missed opportunities.
  • It is not a foolproof way to predict market movements, and traders should always use proper risk management techniques when using this indicator in trading.

The Stochastic RSI is a highly effective technical analysis tool that fuses two popular indicators, delivering traders a more comprehensive understanding of an asset’s momentum.
