ATRPivot - indicator for MetaTrader 5

ATRPivot generates support and resistance levels considering Average True Range (ATR) indicator.

The idea of this indicator was formed based on the ATR Channels indicator code developed by Luis Guilherme Damiani.

The presented variant of this indicator allows to select the smoothing algorithm displayed as a smoothing line out of ten possible variants:

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 Tushar Chande's algorithm;
10. AMA - smoothing with the use of Perry Kaufman's algorithm.

It should be noted that Phase parameter has completely different meaning for different smoothing algorithms.

• For JMA it is an external Phase variable changing from -100 to +100.
  
• For T3 it is a smoothing ratio multiplied by 100 for better visualization;
  
• For VIDYA it is a CMO period, for AMA it is a slow EMA period;
  
• For AMA fast EMA period is 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".
