Definition of Kairi Relative Index

The Kairi Relative Index, also known as the KRI, is a technical indicator used to measure the relative position of an asset's price compared to its historical average. It helps traders identify overbought and oversold conditions in the market, enabling them to make informed trading decisions.

Biography of the Developer

The Kairi Relative Index was developed by Toshihiro Yamada, a renowned technical analyst and trader. Yamada has extensive experience in the financial markets and is known for his contributions to the field of technical analysis. He developed the Kairi Relative Index to provide traders with a reliable tool for assessing market conditions and identifying potential trading opportunities.

Formula and Calculation

The formula used to calculate the Kairi Relative Index is as follows:

KRI = (Current Price - n-period Moving Average) / n-period Moving Average * 100

Here, the current price refers to the most recent closing price of the asset, and the n-period moving average represents the average closing price over a specified number of periods.

How to Use the Kairi Relative Index

The Kairi Relative Index can be used in various ways to aid trading decisions. Here are some key applications:

Identifying Overbought and Oversold Conditions

When the Kairi Relative Index is above 0, it indicates that the current price is above the historical average, suggesting an overbought condition. Conversely, when the index is below 0, it suggests an oversold condition. Traders can use these signals to anticipate potential reversals in price and adjust their trading strategies accordingly.

Confirming Trend Strength

The Kairi Relative Index can also be used to confirm the strength of a trend. If the index is consistently above 0 during an uptrend, it suggests that the trend is strong. Conversely, if the index remains below 0 during a downtrend, it indicates a robust downward momentum. Traders can use this information to validate their analysis and make more confident trading decisions.

Spotting Divergence

Divergence occurs when the price of an asset moves in the opposite direction of the Kairi Relative Index. This can be a powerful signal of a potential trend reversal. For example, if the price is making higher highs while the Kairi Relative Index is making lower highs, it suggests a bearish divergence. Traders can use these divergences to identify potential entry or exit points in the market.

Combining with Other Indicators

The Kairi Relative Index can be effectively combined with other technical indicators to enhance trading strategies. Here are a few common combinations:

Kairi Relative Index and Moving Averages

By combining the Kairi Relative Index with moving averages, traders can gain additional insights into market trends. For example, when the Kairi Relative Index crosses above a moving average, it can signal a bullish trend reversal. Conversely, when the index crosses below a moving average, it suggests a bearish trend reversal. This combination can help traders confirm trend changes and make more accurate trading decisions.

Kairi Relative Index and RSI

Another effective combination is the Kairi Relative Index and the Relative Strength Index (RSI). The RSI is a momentum oscillator that measures the speed and change of price movements. When the Kairi Relative Index and RSI both indicate overbought or oversold conditions, it strengthens the signal, increasing the probability of a successful trade. Traders can use this combination to filter out false signals and focus on high-probability trading opportunities.

Advice to Algorithmic Traders

For algorithmic traders, incorporating the Kairi Relative Index into trading strategies can enhance performance and generate more profitable trades. Here are some tips for algorithmic traders:


Prior to implementing the Kairi Relative Index in live trading, it is crucial to conduct thorough backtesting. This involves testing the indicator on historical data to assess its performance and validate its effectiveness. Backtesting helps traders understand the strengths and weaknesses of the indicator and optimize its parameters for better results.

Optimize Parameters

Algorithmic traders should experiment with different parameters of the Kairi Relative Index to find the optimal settings for their specific trading strategies. The choice of the moving average period and the sensitivity of the indicator can significantly impact its performance. By fine-tuning these parameters, traders can maximize the accuracy and profitability of their trading algorithms.

Combine with Other Indicators

To further enhance trading strategies, algorithmic traders can combine the Kairi Relative Index with other indicators. By leveraging multiple indicators, traders can generate more robust trading signals and increase the overall effectiveness of their algorithms.

Monitor Market Conditions

Algorithmic traders should regularly monitor market conditions and adjust their trading algorithms accordingly. The Kairi Relative Index is not a standalone indicator and should be used in conjunction with other market analysis techniques. By staying updated on market trends and news, traders can make informed decisions and adapt their algorithms to changing market dynamics.


The Kairi Relative Index is a valuable tool for traders, providing insights into market conditions and helping identify potential trading opportunities. By understanding its definition, the biography of its developer, and the formula used to calculate it, traders can effectively incorporate the Kairi Relative Index into their trading strategies. By combining it with other indicators and following the advice provided, both individual and algorithmic traders can enhance their trading performance and achieve greater success in the financial markets.
