Keltner channels are made with the draw_fill style and appear as a colored background fill.

Indicator input parameters:

//+------------------------------------------------+
//|Indicator input parameters |
//+------------------------------------------------+
Input Smooth_Method MA_Method1= Mode_SMA ; // The first smoothing method
Input integer length 1= 40 ; // first smoothing depth
Input integer stage 1 = 15 ; // first smoothing parameter
Enter Smooth_Method MA_Method2=MODE_JJMA; // The second smoothing method
Input integer length 2= 20 ; // second smoothing depth
Input integer stage 2 = 100 ; // second smoothing parameter
Input integer Keltner period = 20 ; // Keltner smoothing period
Enter double ratio = 2.0 ; // first level ratio
Input application_price_IPC= PRICE_CLOSE ; // application price
Enter integer shift = 0 ; // horizontal movement of the indicator in bars
Input integer price movement = 0 ; // vertical movement of the indicator in points

The indicator center line is made using an algorithm with two smoothings, and each of these two smoothings can be selected from a dozen possible versions:

It should be noted that the Phase1 and Phase2 parameters have completely different meanings for different smoothing algorithms. For JMA, it is an external phase variable that varies from -100 to +100. For T3, it is the smoothed ratio multiplied by 100 for better visualization; for VIDYA, it is the CMO oscillation period; for AMA, it is the slow EMA period. In other algorithms, these parameters do not affect smoothing. For AMA the fast EMA period is a fixed value, equal to 2 by default. For AMA, the ratio of raised powers is also equal to 2.

The indicator uses the SmoothAlgorithms.mqh library class (must be copied to terminal_data_folder\MQL5\Include). The use of the class "Average price series for intermediate calculations without using additional buffers" is described in detail in the article.
