This indicator allows to select averaging algorithms out of ten possible versions:

1. SMA - simple moving average
2. EMA - exponential moving average
3. SMMA - smoothed moving average
4. LWMA - linear weighted moving average
5. JJMA - JMA adaptive average
6. JurX - ultralinear smoothing
7. ParMA - parabolic smoothing
8. T3 - Tillson's multiple exponential smoothing
9. VIDYA - smoothing with the use of the Tushar Chande's algorithm
10. AMA - smoothing with the use of the Perry Kaufman's algorithm

It should be noted that Phase parameters for different smoothing algorithms have completely different meaning. For JMA it is the Phase external variable changing from -100 to +100. For T3 it is the smoothing ratio multiplied by 100 for better visualization, for VIDYA it is the CMO oscillator period and for AMA it is the slow EMA period. In other algorithms these parameters do not affect smoothing. For AMA, the fast EMA period has a fixed value and is equal to 2 by default. The ratio of raising to the power is also equal to 2 for AMA.

The indicator uses SmoothAlgorithms.mqh library classes (must be copied to the terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
