In plain terms
This version first scales the advance-decline difference by the number of issues that actually moved, then compares fast and slow trends of that normalized input.
Technical
Define r_t = 1000(A_t-D_t)/(A_t+D_t) when A_t+D_t is nonzero, apply the 10% and 5% recurrences under one initialization policy, and compute RAMO_t = T10_t(r)-T5_t(r).
Scope
Unchanged issues are excluded from this denominator by methodology; zero-denominator status, eligibility, seeding, revision handling, and rounding remain explicit package policies.
Formula
r_t = 1000*(A_t-D_t)/(A_t+D_t); RAMO_t = T10_t(r) - T5_t(r)r_t=1000\frac{A_t-D_t}{A_t+D_t},\quad RAMO_t=T^{10}_t(r)-T^{5}_t(r)| Symbol | Meaning | Unit |
|---|---|---|
A_t | Advancing issue count at t | issues |
D_t | Declining issue count at t | issues |
r_t | Ratio-adjusted breadth input | scaled breadth points |
RAMO_t | Ratio-Adjusted McClellan Oscillator | scaled breadth points |
Output unit: scaled breadth points
Examples
- With 600 advances and 400 declines, the ratio-adjusted input is 200 before the two trends are updated.
Common misconceptions
- Ratio adjustment does not make the oscillator a percentage; the conventional input is scaled by 1000.
