# Regular and Electronic Trading Hours

There are two options for displaying trading sessions for CME Group futures contracts:

* **Electronic Trading Hours (ETH)**: This is the full session for the instrument, based on its official specifications.
* **Regular Trading Hours (RTH)**: This reduced session displays data from 08:30am to 3:15pm CT.

To display and edit the ETH/RTH session break lines on the chart, right-click on the chart, select 'Settings,' and then choose 'Canvas.' To enable session break lines, check the box and adjust your display preferences as needed.

**Restrictions:**

* This feature only affects intraday timeframes; daily, weekly, and monthly timeframes remain the same for both ETH and RTH.

## 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://help.topstepx.com/components/tradingview-tm-charts/regular-and-electronic-trading-hours.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.
