When smoothing data there is always a trade-off between lag and removal of noise. Gaussian filter has a consistently low lag and a very smooth curve.
This filter works for poles higher than the 4 (usual usage). Mathematically maximum poles is 15 after which coefficients are too high to see any difference.
By tuning Lag and number of Poles you can achieve a very smooth MA with least lag possible. It's just as good as 3rd gen moving averages and can be used as input feed for other indicators.
