The Klinger Volume Oscillator (KVO, also named Klinger Oscillator) was developed by Stephen J. Klinger . Learning from prior research on volume by such well-known technicians as Joseph Granville, Larry Williams , and Marc Chaikin, Mr. Klinger set out to develop a volume-based indicator to help in both short- and long-term analysis.
Developed by Donald Dorsey, the Inertia Indicator is an extension of Dorseys Relative Volatility Index and is used to define the long-term trend and how far it has extended. Its name refers to the physics term and its reference to direction and mass of motion. Dorsey states that a trend is simply the “outward result of inertia” and as such, the market will require much more energy to reverse its direction than to extend the ongoing move.
