The FIR (finite impulse response) Hamming is an indicator that filters the data to find the balance between the simple moving average's filtering capability and its lagging. This filter uses a weighting system for data points: the first and the last data point are by default assigned a weight equal to sin10° (so-called pedestal), and data points between them are assigned weights consistent with sinewave half-cycle, peaking in the middle of the indicator length. Thus, most of the weight is given to data around the middle of the indicator's length, and least of the weight is given to data points at the beginning and the end of it. 

The calculation of this filter is consistent with the formula of the Hamming window function.
