/// This is a reversal strategy that uses stochastic oscillators and price action to identify and capitalize on reversals in price.
/// This strategy checks the price action of the underlying symbol to ensure price has started to move in the desired direction and uses stochastic oscillators to determine whether the symbol is currently oversold or overbought.
/// A long signal is generated when price has increased over the most recent two bars, the %K line is below the %D line, and the %K line is below the specified trigger level.
/// A short signal is generated when price has decreased over the most recent two bars, the %K line is above the %D line, and the %K line is above the specified trigger level.
/// This strategy was originally developed and discussed by Ulf Jensen in his 1994 book, “How I Tripled My Money In The Futures Market.”
///
/// Trading Rules:
///
/// Long Entry: A buy market order is generated when the Close price has increased over the most recent two bars, the %K line is below the %D line, and the %K line is below the specified trigger level.
/// Long Exit: A sell market order is generated when the Close price has decreased over the most recent two bars, the %K line is above the %D line, and the %K line is above the specified trigger level.
///
/// Short Entry: A sell short market order is generated when the Close price has decreased over the most recent two bars, the %K line is above the %D line, and the %K line is above the specified trigger level.
/// Short Exit: A buy-to-cover market order is generated when the Close price has increased over the most recent two bars, the %K line is below the %D line, and the %K line is below the specified trigger level.
