One of the key advantages of derivatives is leverage. Leverage enables financial markets participants to build sophisticated trading and portfolio strategies that utilize multiple financial instruments with lower amounts of capital with not necessarily higher risk.

To increase traders’ liquidity and financing flexibility, OptiFi designs Portfolio Margining. The below section provides an overview of our unique OptiFi margin and risk management system designed specifically for DeFi, an introduction to portfolio margin calculation approach, and liquidation framework for account risk management:

## 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://optifi.gitbook.io/optifi/optifi-in-depth/margin-requirements.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.
