XMA-XN - MetaTrader 5 Script | Forex Indicator Download - MT4/MT5 Resources - MetaTrader 5 Resources

A fan formed by one hundred XMA moving averages.

Indicator buffers are declared with the simplest class for code optimization:

//+------------------------------------------------------------------+
//| Array of variables for creating indicator buffers |
//+------------------------------------------------------------------+
ClassCIndicatorsBuffers
  { People : Double IndBuffer[];
  }; //+------------------------------------------------------------------+
//|Indicator buffer creation |
//+------------------------------------------------------------------+ CIndicatorsBuffers Ind[LINES_TOTAL];

If you want to change the number of lines on the chart, you should only change the value of the LINES_TOTAL constant:

//+------------------------------------------------+
//| Constant declaration |
//+------------------------------------------------+
#Define LINES_TOTAL 100 // Constant number of indicator lines

The indicator allows choosing a smoothing type from ten possible versions:

It should be noted that the Phase type parameters of different smoothing algorithms have completely different meanings. 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.

Indicator input parameters:

//+------------------------------------------------+
//| Indicator input parameters |
//+------------------------------------------------+
Input integer steps = 10 ; // interval step size
Input Smooth_Method xMA_Method=MODE_JJMA; // Average method
Input integer x length = 3 ; // smooth depth
Input integer x phase = 100 ; // smoothing parameter
Input Application_Price_IPC= PRICE_CLOSE ; // Price constant
Enter integer shift = 0 ; // horizontal movement of the indicator in bars
Input integer price movement = 0 ; // vertical movement of the indicator in points
input integer color width = 40 ; // palette width (changed from 0 to 131)

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.
