# Replace position You can edit all the attributes of a position from here: * Add margin * Remove margin * Edit leverage * Switch side, i.e long -> short or short -> long {% hint style="success" %} This is the Swiss-knife feature. {% endhint %} {% hint style="danger" %} This feature doesn’t exist on Hyperliquid — we built it from scratch. To reproduce it there, you would need to close your position and reopen a new one. If that’s required, a message will be displayed informing you that your current position will be closed and a new one opened. This also means you’ll pay fees twice and your PnL will be reset. {% endhint %} {% embed url="" %} Perps - Edit position {% endembed %} --- # 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.
