# GET /private/change_margin_model

`GET /private/change_margin_model`

Changes the margin model for the authenticated account or a specified subaccount. Margin models determine how margin requirements are calculated (e.g., Standard Margin vs. Portfolio Margin).

Changing the margin model may affect margin requirements, available funds, and trading capabilities. Use the `dry_run` parameter to preview the impact of the change before applying it.
