# How to add an ACS Button to a control bar?

Some custom studies that are offered at SST use ACS buttons to get a trigger form user interaction (pushing a button). To use these custom studies properly you will need to add an ACS to your control bar.

Let me quickly explain how this is done.

### Menu Settings

In SC menu go to **Global Settings >> Customize Control Bar >> Control Bar**

### Setup window

A setup window will pop-up which allows you to add certain button functionality to your control bar.

### Adding buttons

Select "Advanced Custom Study Buttons" on the left side and click the desired number you wish to add to you bar. Click the "Add" button. The right-hand side of the window shows you the buttons that are currently present on your control bar.

### Reference number

Each ACS button has a certain number. This reference number is used to identify the button. In most cases you will need to use that reference number in the custom study settings that require you to setup and ACS button.

## 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.simplesystemtrading.com/faqs/sierra-chart-faqs/how-to-add-an-acs-button-to-a-control-bar.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.
