Technical analysis relies on a vast arsenal of indicators to gauge price movements and identify potential trading opportunities. Two prominent momentum oscillators vying for attention are Connors RSI (CRSI) and Stochastic RSI (Stoch RSI). This blog dives into the world of these indicators, dissecting their calculations, and interpretations, and highlighting the key differences to empower you to make informed choices for your trading strategy.

What is Connors RSI?

The Connors RSI (CRSI) is a technical indicator derived from the well-known Relative Strength Index (RSI) but incorporates additional elements to enhance its responsiveness to price changes. Here's a glimpse into its core:

  • Calculation: CRSI factors in the RSI value, the Rate of Change (ROC) of the price, and the difference between the closing price and the moving average closing price. This combination aims to capture not just the magnitude of price changes but also their momentum and direction.
  • Interpretation: Similar to RSI, CRSI readings range from 0 to 100. Values above 70 generally indicate overbought conditions, while readings below 30 suggest oversold conditions. However, CRSI often generates fewer signals compared to RSI but aims for those signals to be more precise.

What is Stochastic RSI?

The Stochastic RSI (Stoch RSI) is a refinement of the classic Stochastic Oscillator. It adds another layer of analysis by applying the Stochastic Oscillator formula to the RSI values instead of the raw price data to help with your options trading. Let's break it down:

  • Calculation: Stoch RSI involves calculating the %K (fast %RSI) and %D (slow %K) based on the closing price, the highest high, and the lowest low within a specific time period (often 14 days). These values are then plotted to create an oscillator that fluctuates between 0 and 100.
  • Interpretation: Stoch RSI readings above 80 are typically considered overbought, while readings below 20 suggest oversold conditions. However, due to its focus on short-term price movements, Stoch RSI can generate more frequent signals compared to CRSI.

Connors RSI vs. Stochastic RSI

While both CRSI and Stoch RSI serve as momentum oscillators, some key distinctions set them apart:

  • Responsiveness: CRSI is generally considered more responsive to price changes than Stoch RSI. This can be beneficial for identifying short-term trading opportunities but might also lead to more frequent whipsaws (false signals).
  • Signal Frequency: Stoch RSI tends to generate more trading signals due to its focus on short-term price fluctuations. CRSI, on the other hand, aims for fewer but potentially more precise signals.
  • Overbought/Oversold Levels: CRSI uses the traditional RSI thresholds of 70 and 30 for overbought and oversold conditions, respectively. Stoch RSI employs more extreme levels of 80 and 20.

Which is the right RSI indicator for you?

The optimal choice between Connors RSI and Stochastic RSI depends on your trading style and risk tolerance:

  • Short-Term Traders: If you're a short-term trader who thrives on identifying frequent trading opportunities, Stoch RSI might be a better fit due to its higher signal frequency.
  • Active Traders Seeking Precise Signals: Active traders prioritising high-probability signals might favour CRSI, even though it generates fewer alerts.
  • Combining Indicators: Consider incorporating both CRSI and Stoch RSI into your strategy. Use Stoch RSI for initial signal generation and CRSI for confirmation or to filter out potential false signals.


Both Connors RSI and Stochastic RSI are valuable tools for technical analysis, offering insights into momentum and potential turning points in the market. Understanding their individual characteristics and how they complement each other can empower you to make informed trading decisions. Remember, no single indicator is a crystal ball. Always practise proper risk management and combine technical analysis with other forms of market research before executing trades.
