GetVolume

Description

This formula accesses the volume of a daily bar. Use the index parameter to specify the bar, or daily session, you want to access. 0 is the current session, 1 is yesterday's session, etc.

Formula

GetVolume(instrument, index)=begin

  targetBar = index - 1

  retval = vchart(instrument.volume[targetBar])

end

Parameters

instrument

The instrument argument specifies which instrument to evaluate.

index

The index parameter enables you to specify the bar for which you want to retrieve volume. Use 0 to specify the current bar, 1 to specify the first bar back, 2 to specify the second bar back, etc.

Return Value

The volume of the specified daily bar.

Examples

MoneyFlow_1(instrument, Length)=begin

  pmf = 0

  nmf = 0

  avp = 0

  volVal = 0

  MoneyRatio = 0

  MoneyFlow = 0

  for i = 0 to (Length - 1) begin

    avp = AvgPrice(instrument, i)

    pavp = AvgPrice(instrument, (i + 1))

    volVal = avp + GetVolume(instrument, i)

    if avp > pavp then pmf = pmf + volVal + avp else nmf = nmf + volVal

  end

  if nmf != 0 then MoneyRatio = pmf / nmf else MoneyRatio = 0

  if (1 + MoneyRatio) != 0 then MoneyFlow = 100 - (100 / (1 + MoneyRatio)) else MoneyFlow = 0

  MoneyFlow

end
