Klinger Oscillator

The Klinger Volume Oscillator (KVO), developed by Stephen Klinger, is a technical indicator that uses volume and price to determine the long-term direction of money flow while remaining responsive to short-term price movements. It calculates "Volume Force" by combining price trend direction with volume and the daily price range (high-low), then applies two exponential moving averages (typically 34-period and 55-period) to create the oscillator. A 13-period EMA of the KVO serves as the signal line. The oscillator fluctuates above and below zero: positive values indicate buying pressure dominates, negative values indicate selling pressure. Buy signals occur when the KVO crosses above its signal line (especially when below zero — buying emerging from oversold territory), and sell signals when it crosses below (especially when above zero). The indicator is particularly valuable for identifying divergences: when price makes new highs but the KVO makes lower highs, it warns of weakening buying pressure and potential reversal. The Klinger Oscillator is most effective when combined with trend-following indicators to filter signals in the direction of the prevailing trend.
