What it does
Maintains a stateful sum, max, min, average, or count of the source, with optional include and reset gates.
What happens
Each candle the value updates per its mode; it persists across bars and only resets when the reset gate fires.
When to use
Cumulative metrics — count signals, running totals, session aggregates.
Gotchas
- Without a reset gate it accumulates for the whole run.
- Pick the mode deliberately — sum, avg, and count behave very differently.
