# Brokers and Market Makers
Brokers and market makers enter into transactions to generate fees and profit on spreads. Their activity provides liquidity to the market. Often the broker will enter into one or more corresponding trades to keep their positions risk-neutral. Some will offer markets across a wide range of rates derivatives while others may limit their activity to a specific sector or type of swap.

## 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.swivel.finance/other-resources/institutions/rate-profile-optimization/page-untitled-1/5untitled.md?ask=&goal=
```
`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.
