Definitions
In plain terms
This oscillator applies the McClellan fast-versus-slow comparison to trading volume assigned to advancing and declining issues instead of to issue counts.
Technical
For volume-difference input V_t = UV_t - DV_t, compute the 10% and 5% recursive trends under one declared initialization policy and return MVO_t = T10_t(V)-T5_t(V).
Scope
The volume-input and 10/5 trend relationship are sourced; volume eligibility, allocation, units, corporate-action treatment, seeding, revisions, and missing sessions require explicit package policies.
Formula
V_t = UV_t - DV_t; MVO_t = T10_t(V) - T5_t(V)V_t=UV_t-DV_t,\quad MVO_t=T^{10}_t(V)-T^{5}_t(V)| Symbol | Meaning | Unit |
|---|---|---|
UV_t | Up Volume at t | share-volume units |
DV_t | Down Volume at t | share-volume units |
V_t | Volume-difference input | share-volume units |
MVO_t | McClellan Volume Oscillator | share-volume units |
Output unit: share-volume units
Examples
- If the ready fast volume trend is 1.8 million shares and the slow trend is 1.5 million shares, the oscillator is 0.3 million shares.
Common misconceptions
- The Volume Oscillator is not the issue-count McClellan Oscillator multiplied by total market volume.
