Period	Description	Period
Submission period	Time window for the data provider to report the outcome	7 days following pool expiration
Challenge period	Time window for position token holders to challenge a reported value (only applicable if the option to challenge was given by the data provider)	3 days starting from the time of a final value submission by the data provider
Review period	Time window for the data provider to react to a challenge and report a new outcome	5 days starting from the time of the first challenge
Fallback submission period	Time window for the fallback provider to report a value	10 days starting from the expiration of the submission period

The timelines represent initial values and can be updated by the DIVA Protocol owner at a later stage with values ranging from a minimum of 1 day to a maximum of 15 days. Further, it's important to note that any changes made will exclusively impact new pools and will not have any effect on existing outstanding pools. The settlement process is illustrated below and discussed in more detail in the following sections. Also, refer to the official [smart contract documentation](https://github.com/divaprotocol/diva-protocol-v1/blob/main/DOCUMENTATION.md#settlement-process) for more details.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.divaprotocol.io/introduction/what-is-diva-protocol/how-it-works/settlement/timelines.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.
