Syntax
public MoneyFlow(Bars bars, string description)
public static MoneyFlow Series(Bars bars)
Parameter Description
Description
Money Flow returns the average price multiplied by volume. Money Flow is the core component of the
Money Flow Index (MFI) indicator. This is not really an indicator, but a mathematical function used to construct other indicators.
Interpretation
See the
Money Flow Index (MFI) indicator and the example strategy application below.
Calculation
Money Flow is the average price multiplied by Volume.
Money Flow = Volume x
