Smoothed ATR, recalculated as price chart points.

It uses color to show whether the trend strengthens or weakens. The red color corresponds to the trend strengthening, the yellow color corresponds to the trend weakening.

Indicator input parameters:

```//+-----------------------------------+
//| Indicator input parameters        |
//+-----------------------------------+
input int ATRPeriod=12;                   // ATR period
input Smooth_Method XMA_Method=MODE_JJMA; // Smoothing method
input int XLength=5;                      // Smoothing depth
input int XPhase=15;                      // Smoothing parameter
input int Shift=0;                        // Horizontal shift of the indicator in bars ```

You can change averaging algorithms out of ten possible options in the indicator:

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

It should be noted that Phase parameters for different smoothing algorithms have completely different meaning. For JMA, it is an external Phase variable that varies from -100 to +100. For T3, it is a smoothing coefficient multiplied by 100 for better visualization. For VIDYA, it is a CMO oscillator period. And for AMA, it is a slow EMA period. These parameters do not affect the smoothing in other algorithms. For AMA, the fast EMA period is a fixed value and is equal to 2 by default. The powering coefficient for AMA is also fixed at 2.

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