# Cross Margin Cross Margin positions use the full balance as margin and allow the trader to increase the size of the position on the fly allowing for dollar cost averaging. When multiple position openned, the PnL from each position will be counted towards the margin (collateral) of the other cross margin positions (on the same margin currency) {% hint style="info" %} When a user has multiple Cross-Margin positions opens and one position reaches its liquidation price, all cross margin positions for the collateral are liquidated (market closed). This is done in order to protect hedged positions so there is no scenario in which one leg of the hedge is liquidated and the other stays open. {% 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.
