Definitions
In plain terms
It provides a boundary that was knowable before the current bar completed.
Technical
At row t it uses the aligned channel state from t-1, with its own complete lookback and no current-row contamination.
Scope
Lagging the boundary changes comparison timing but does not redefine the underlying current-inclusive channel.
Examples
- A reviewer traces Prior Completed Channel from aligned inputs through its first-ready row and edge cases before accepting a displayed value.
Common misconceptions
- Lagging the boundary changes comparison timing but does not redefine the underlying current-inclusive channel.
