# Phase 4: Settlement

**Position Updates**

* New position states calculated
* Funding payments accrued
* Realized PnL computed
* Margin requirements updated

**On-Chain or Commitment** Position state updates are either:

* Written directly to chain (lower throughput, maximum transparency)
* Recorded as verifiable commitment to state root (higher throughput, still verifiable)

**Funding Settlement** Premium between mark price and index price is settled based on time-weighted average.

## 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.opaldex.com/order-lifecycle/phase-4-settlement.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.
