Definitions
In plain terms
It tracks whether advancing or declining securities have accumulated more volume over time.
Technical
The recurrence needs aligned volume inputs, a declared starting level, chronological order, missing-session policy, and revision handling.
Scope
Its absolute level depends on the chosen start and is not directly comparable across implementations.
Formula
ADVL_t = ADVL_(t-1) + UV_t - DV_tADVL_t=ADVL_{t-1}+UV_t-DV_t| Symbol | Meaning | Unit |
|---|---|---|
ADVL_(t-1) | prior cumulative line level | shares or contracts |
UV_t | current up volume | shares or contracts |
DV_t | current down volume | shares or contracts |
Output unit: shares or contracts
Examples

Common misconceptions
