Chebyshev probability models determine Buy-Sell-Stop probabilities and Buy-Sell signals. The Chebyshev Theorem describes the percentage of data that falls within a given number of standard deviations of the mean. Simply enter the stock and transaction amount and press GO to obtain up to four Buy-Sell scenarios including number of shares, entry and exit prices and transaction probabilities with Buy-Sell signals. The Buy-Sell prices, gain and trend are obtained through pivot point linear regression at the four Fibonacci time periods.
