CMF Ratio-of-Sums

CMF ratio-of-sums divides summed money-flow volume by summed volume.

Definitions

In plain terms

The ratio is calculated after summing the window, not by averaging individual multipliers equally.

Technical

CMF_t = (Σ MFM_i V_i)/(Σ V_i), which preserves volume weighting across bars.

Scope

A simple mean of MFM values can differ materially when bar volumes differ.

Formula

CMF_t = (Σ MFM_i V_i)/(Σ V_i)
LaTeX: CMF_t = \frac{\sum MFM_iV_i}{\sum V_i}

Examples

  • A reviewer computes CMF Ratio-of-Sums from a small OHLCV fixture and checks readiness, units, and edge cases before publication.

Common misconceptions

  • A simple mean of MFM values can differ materially when bar volumes differ.
