# Sessions

<figure><img src="/files/zY5W4ooZhYqd5wRmvXHa" alt=""><figcaption></figcaption></figure>

The market moves in cycles of time. The **Sessions** component of the OHLC Expansion Map provides precision mapping for specific trading windows where institutional volatility is highest.

### Predefined Sessions

The indicator comes with several industry-standard sessions pre-configured:

* **Asia Session (AS):** 20:00 - 00:00 (NY Time). Often characterized by accumulation or consolidation.
* **London Open (LO):** 02:00 - 05:00 (NY Time). The "Killzone" where the daily high or low is often formed.
* **NY AM Session (NYAM):** 09:30 - 11:00 (NY Time). High-intensity expansion following the equities open.
* **NY Lunch (NY LA):** 12:00 - 13:00 (NY Time). Typically a period of retracement or consolidation.
* **NY PM Session (NYPM):** 13:30 - 16:00 (NY Time). Late-day distribution or trend continuation.

### Custom Sessions

If you trade specific markets (like London Equities, Crypto, or Forex pairs with specific news events), you can use the **Custom Session** slot. Simply enter the time in `HHMM-HHMM` format.

### Features

#### NY Midnight Open

For all session-based statistics, you have the option to anchor the "Daily Open" to the New York Midnight price. This is critical for ICT-based trading strategies where the "True Day" begins at 00:00 EST.

#### Dynamic Zone Extension

* **End of Period:** Zones extend from the session start to the calculated session end time.
* **Current Bar:** Zones extend dynamically to the current time, providing a live "real-time" view of the expansion.

### Best Practices

* **Color Coding:** Use distinct colors for each session to quickly identify which "Killzone" you are currently trading in.
* **Overlap Analysis:** Look for instances where a Higher Timeframe (TF2) Distribution zone overlaps with a Session (LO) Manipulation zone—these are often high-probability reversal points.

## 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/sessions-1.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.
