FTB-C000560 / Implementation concept

MFI Warm-Up Window

MFI warm-up window is the history required to classify the first complete set of flows.

Definitions

In plain terms

A 14-period MFI needs a prior typical price for each of 14 classified changes.

Technical

For period 14, the first ready index is 14 because 15 typical prices are needed to form 14 comparisons.

Scope

Off-by-one readiness errors shift every early value and must be tested explicitly.

Examples

  • A reviewer computes MFI Warm-Up Window from a small OHLCV fixture and checks readiness, units, and edge cases before publication.

Common misconceptions

  • Off-by-one readiness errors shift every early value and must be tested explicitly.

  1. Money Flow Index (MFI) TradingView · official platform documentation

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: Common overbought/oversold zones are descriptive conventions, not probabilities or guarantees.

  2. Money Flow Index technical note TA-Lib · first party technical publication

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: A library note does not settle application-specific edge cases or locale wording.

  3. Volume indicators function group TA-Lib · first party technical publication

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: Library compatibility does not by itself prove a project's seed, warm-up, or missing-data policy.

  4. Closing Price Investor.gov · official standard

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: A close is not automatically an adjusted close and may vary by market session convention.
