Indicator Heiken_Ashi_Smoothed_VolatilityStep without rounding, multiplied by the averaged volumes.

//+----------------------------------------------+  //|  INDICATOR INPUT PARAMETERS                  |  //+----------------------------------------------+  input Smooth_Method     HMA_Method=MODE_T3;        // Smoothing method  input uint              HLength=12;                // Depth of averaging                      input int               HPhase=100;                // Parameter of averaging,  3//---- for JJMA within the range of -100 ... +100 it influences the quality of the transition process;  //---- for VIDIA it is a CMO period, for AMA it is a slow average period  input ENUM_APPLIED_VOLUME VolumeType=VOLUME_TICK;  // volume   input int               Shift=0;                   // horizontal indicator shift in bars  

The indicator uses SmoothAlgorithms.mqh library classes (copy it to <terminal_data_folder>\MQL5\Include). The use of the classes was described in detail in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
