Parameters ------------------ Signal         The entry/exit signal to evaluate. The signal parameter does not need to be formatted to be displayed as a signal to be used in this function. Function Value ------------------------ If the signal is currently a short signal, it returns the current value of the signal. A short signal is defined to be an enter short signal or an exit short signal. If it is not a short signal, it returns the value from the last evaluation.
