What it does
Fires once, on the bar where A transitions from ≥ B to < B.
What happens
Evaluated every candle over its resolved inputs and emits true or false. A missing input is treated as false, never an error.
When to use
Exit or short triggers — e.g. fast EMA crossing below slow EMA.
Gotchas
- Only true at the crossing bar; needs a previous bar to evaluate.
