# Alerts

Momentum Concepts offers specialized alerts for trend shifts, signals, and statistical reversal signatures.

### Available Alert Types

1. **Momentum Signals**:
   * **Any Buy Signal**: Triggered when any level of buy signal (L1, L2, or L3) occurs.
   * **Any Sell Signal**: Triggered when any level of sell signal (L1, L2, or L3) occurs.
2. **Reversal Probabilities**:
   * **Bottom Probability**: Triggered when the KNN Bottom Reversal Engine confirms a bottoming pattern.
   * **Top Probability**: Triggered when the KNN Top Reversal Engine confirms a topping pattern.

### Advanced Alert Strategy

For maximum efficiency, you can set an alert on the **Any Alert() function call**. This will send a notification for:

* Standard, Strong, and Elite signals.
* Confirmed machine-learning reversals.

### Alert Content

Alerts are pre-configured with descriptive text (e.g., "Momentum Buy Signal (L2) detected") so you can identify the setup directly from your mobile device or desktop notification without opening the chart.

### Frequency

Most alerts are set to **Once Per Bar Close**. This is essential for KNN and Signal analysis to ensure the bar has finished calculating and the momentum transition is sustained.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.candelacharts.com/oscillators/momentum-concepts/alerts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
