This function evaluates the calculated values from an indicator using a parabolic function. After the optimum is reached the it stays at its plateau.
evaluate_parabolic(x, x.top)(numeric) The values of a calc function to be converted to an evaluation
(numeric) The value at which x reaches the plateau
A transformed variable after applying a parabolic evaluation function. A numeric value.
