# forge.signals.count

```python
forge.signals.count(condition: np.ndarray | ConditionTree, /, *, over: int) -> np.ndarray
```

The number of bars among this bar and the ``over - 1`` before it where the condition is true.

``count(rsi > 50, over=3) >= 3`` means above 50 for the last three bars. A comparison of the
result gives a True/False array, so it combines like any condition.
