Money Flow calculates the typical price multiplied by volume. Money Flow is the core component of the Money Flow Index (MFI) indicator. Money Flow itself is not an indicator, rather a mathematical function used to construct other indicators.
How this indicator works
See the Money Flow Index (MFI) definition and application
