The HWMA indicator (Holt-Winter Moving Average) is a three-parameter moving average using the Holt-Winter method; these three parameters should be selected to obtain predictions.

The indicator has four input parameters:

 HWMA[i] = F[i] + V[i] + 0.5 * A[i]

Where:

 F[i] = (1-nA) * (F[i-1] + V[i-1] + 0.5 * A[i-1]) + nA * Price[i]
V[i] = (1-nB) * (V[i-1] + A[i-1]) + nB * (F[i] - F[i-1])
A[i] = (1-nC) * A[i-1] + nC * (V[i] - V[i-1])
