Creator of the Klinger Volume Oscillator

Stephen J. Klinger

Stephen J. Klinger, CMT, is a technical analyst who designed the Klinger Volume Oscillator to track long-term money flow while staying responsive to short-term swings in volume. He described it in 'Identifying Trends With Volume Analysis' in Technical Analysis of Stocks & Commodities in December 1997.

What they argue

  • Volume is a proxy for money flow and reveals the internal strengths and weaknesses of price action.
  • The most powerful signal is an extreme reading above or below zero that reverses, warning that the trend is exhausted.
