Kairi Relative Index

The Kairi Relative Index is a technical indicator of Japanese origin that measures how far the current price has deviated from its simple moving average (SMA), expressing that deviation as a percentage. It is calculated by subtracting the SMA from the current price, dividing by the SMA, and multiplying by 100. A positive result indicates the price is trading above its average — potentially overbought — while a negative result indicates it is below the average — potentially oversold. The indicator is conceptually similar to the percentage price oscillator and serves as an early precursor to more modern mean-reversion tools.

The Kairi Relative Index is interpreted through fixed threshold levels. When the index rises above a certain positive percentage, the asset is considered extended to the upside and a sell signal may be generated. When it falls below a certain negative percentage, the asset is considered oversold and a buy signal may be triggered. These thresholds vary depending on the asset and time frame — a highly volatile cryptocurrency will require wider thresholds than a more stable asset. The indicator is most useful in ranging markets where prices oscillate around a central mean, consistently generating reversal signals at the extremes.

For automated crypto trading, the Kairi Relative Index provides a clean and transparent measure of price extension relative to trend. Its simplicity is both a strength and a limitation: it works well in mean-reverting conditions but can generate false signals during sustained trending markets where the price stays consistently above or below the moving average for extended periods. Bot traders often use it as a secondary filter within a larger strategy — for example, confirming entries only when both the Kairi Relative Index and a momentum oscillator like RSI simultaneously signal oversold conditions, reducing the risk of catching a falling knife during a genuine downtrend.
