The **OHLC Expansion Map** is a comprehensive suite of tools designed to provide a 360-degree view of market statistics. It operates by layering multiple layers of data on your chart, all calculated relative to specific "Opening Prices."

It provides a multi-layered view of the market, integrating high-timeframe projections, precision session mapping, and ICT macro windows to identify high-probability institutional interest zones.&#x20;

By layering behavioral levels with dynamic volatility and real volume data, the map transforms raw price action into an objective, data-driven framework for anticipating daily and session-based expansions.

## 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/statistics/ohlc-expansion-map/overview.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.
