VAMA (Velocity and Acceleration Moving Average).

There are three adjustable parameters:

• Period - calculation period;
• Applied price - the calculation price;
• Double smoothing - enable or disable double smoothing (Yes/No).

D1[i] = EMA[i] - EMA[i-Period/4]  D2[i] = EMA[i] - 2 * EMA[i-Period/4] + EMA[i-Period/8]  D3[i] = EMA[i] - 3 * EMA[i-Period/4] + 3*EMA[i-Period/8] - EMA[i-Period/12]
