Sorry I am new to this. Alpha (how fast the curve reacts to the price movement by giving higher weightage to recent prices), and gamma (trend component adapts to change in data) . What is the range of values for both alpha and gamma? Are both alpha and gamma length range from from 1 - 100? The recommended value to be 20 for both alpha and gamma values? Thanks in advanced.
Thanks in advanced.
