# Position Buffer Vortex v1 will remain at 1x leverage, but, as USDC is used as collateral, positions are at risk of liquidation. To manage this risk, a percentage of funds are held idle in an address as a **Position Buffer**. This is done to increase the available collateral in the margin account such that the margin account is always overcollateralised, dramatically reducing any liquidation risk. This Buffer is a set size and will be maintained so long as active positions are open. The Buffer can be changed at any time by the Vortex Manager; *remargin()* must be called after the buffer change. {% hint style="info" %} *For more information, on how this is managed during strategy operation see* [*remargin*](/akropolis/developer-documentation/vortex/risk-management/remargin.md) {% endhint %} --- # 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.
