Adaptive Kalman Filter returns filtered (smoothed) data, transferred in the Price parameter. The Length parameter, defining the filtering period, is similar to the Length parameter in the moving averages, for example, in EMA. The sharpness influences the smoothness and its value is set as a value within the range from 1 to 10. The greater this parameter is, the higher will be the smoothness of the resulting data. The recommended value is 2,3.
