What it does
Fires once, on the bar where A transitions from ≤ B to > B.
What happens
Evaluated each candle using the current and previous values of both inputs; emits true only at the crossing bar, false otherwise.
When to use
Entry triggers — e.g. fast EMA crossing above slow EMA.
Gotchas
- Only true at the crossing bar, not while A stays above B — use Compare for a level.
- Needs a previous bar; it can't fire on the very first candle.
