+#### has_any_lower_then_threshold
+
+The `has_any_lower_then_threshold` function checks if any value in a given column is lower than a specified threshold within the last N data points. This is useful for detecting when an indicator or price falls below a critical level.
+
+```python
+def has_any_lower_then_threshold(
+    data: Union[pd.DataFrame, pl.DataFrame],
+    column,
+    threshold,
+    strict=True,
+    number_of_data_points=1
+) -> bool:
+    ...
+```
+
+Example
+
+```python
+import pandas as pd
+from pyindicators.indicators.utils import has_any_lower_then_threshold
+
+# Example DataFrame
+prices = pd.DataFrame({
+    'Close': [100, 98, 97, 99, 96, 95, 97, 98, 99, 100]
+})
+
+# Check if any of the last 5 closes are below 97
+result = has_any_lower_then_threshold(prices, column='Close', threshold=97, number_of_data_points=5)
+print(result)  # Output: True
+```
+
+Below is a chart showing the threshold and the points where the condition is met:

+![has_any_lower_then_threshold](https://github.com/coding-kitties/PyIndicators/blob/main/static/images/indicators/has_any_lower_then_threshold.png)
+
+In this chart, the red line represents the threshold, and the highlighted points are where the `Close` value is below the threshold in the last N data points.
