Once connected, you can **fetch the Net Asset Value (NAV)** from your selected provider using the **Fetch** button in the **Valuation Form**, helping reduce manual data entry and keeping valuations consistent and up to date. #### Key Features * Connect supported external portfolio or custody providers. * Fetch NAV data on demand directly from the Valuation Form. * Reduce manual input errors and streamline the valuation workflow. #### Supported Providers The **Supported Providers** subpages contain the full list of available Portfolio Value Providers. Each provider page includes detailed instructions explaining how to connect and configure the integration. --- # Agent Instructions: 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.
