iVolumes

The function returns the handle of the Volumes indicator.  It has an only one buffer.

int  iVolumes(    string               symbol,             // symbol name    ENUM_TIMEFRAMES      period,             // period    ENUM_APPLIED_VOLUME  applied_volume      // volume type for calculation    )

Parameters

symbol

[in] The symbol name of the security, the data of which should be used to calculate the indicator. The NULL value means the current symbol.

period

[in] The value of the period can be one of the ENUM_TIMEFRAMES values, 0 means the current timeframe.

applied_volume

[in]   The volume used. Can be any of the ENUM_APPLIED_VOLUME values.

Return Value

Returns the handle of a specified technical indicator,  in case of failure returns INVALID_HANDLE. The computer memory can be freed from an indicator that is no more utilized, using the IndicatorRelease() function, to which the indicator handle is passed.

Example:

long currentbar_volume = iVolume(NULL,0,0);
long previousbar_volume = iVolume(NULL,0,1);

Please, could anyone help me?

I'm trying to use the code below, but always return 0

int vol_filter()
   {
    int volumes = iVolumes(_Symbol,PERIOD_M30,VOLUME_REAL);
    double vol_buffer[];
    int result;
    result = CopyBuffer( volumes ,0,0,1, vol_buffer );
    if (result == -1)
      return (0);
    else 
      result = vol_buffer[0];
      return (result);
         
         
   }
