Money Flow Index (MFI)

Created by Quong and Soudack, the Money Flow Index is a price-volume oscillator that shows buying and selling momentum. [Discuss] 💬

// C# usage syntax
IEnumerable<MfiResult> results =
  quotes.GetMfi(lookbackPeriods);

Parameters

lookbackPeriods int - Number of periods (N) in the lookback period. Must be greater than 1. Default is 14.

Historical quotes requirements

You must have at least N+1 historical quotes to cover the warmup periods.

quotes is a collection of generic TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Response

IEnumerable<MfiResult>

• This method returns a time series of all available indicator values for the quotes provided.
• It always returns the same number of elements as there are in the historical quotes.
• It does not return a single incremental indicator value.
• The first N periods will have null MFI values since they cannot be calculated.

MfiResult

Date DateTime - Date from evaluated TQuote

Mfi decimal - Money Flow Index

Utilities

• .Condense()
• .Find(lookupDate)
• .RemoveWarmupPeriods()
• .RemoveWarmupPeriods(qty)

See Utilities and helpers for more information.

Chaining

Results can be further processed on Mfi with additional chain-enabled indicators.

// example
var results = quotes
    .GetMfi(..)
    .GetRsi(..);

This indicator must be generated from quotes and cannot be generated from results of another chain-enabled indicator or method.
