An ultimate oscillator program for the HP-41C(V) by Charles F. Johnson
Johnson describes the stochastic oscillator program he uses on his Hewlett-Packard HP-41C(V) hand-held calculator.
Relative strength and related types of indicators have long been used by the investment community to
reveal potential overbought and oversold levels of price movements. In oscillator form, such indicators
can sometimes be helpful in predicting a change in direction of price movement. Divergences between a
properly designed oscillator and the price of the stock or commodity may have predictive value at "tops"
and "bottoms" of price movements. Obviously, such indicators are not the sole basis for an investment or
In the August, 1985 issue of Technical Analysis of Stocks & Commodities magazine, Larry Williams
outlined an "Ultimate Oscillator." (The October, 1985 issue contained an addendum to the method of
computation on page 6 under "Correction.") In this article and in the brief note in the October, 1985
issue, the computation of the oscillator is discussed. This oscillator uses "buying units" and "total
activity." The change in buying units (BU) in relation to the level of total activity (TA) results in
overbought (top) or oversold (bottom) conditions.
