We use the marked price to calculate margin rates to avoid forced closing due to non-liquidity or market manipulation. #### **Ladder maintenance margin rates** In order to prevent large positions from bursting from the impact on market liquidity, resulting in large losses, we use a ladder mechanism to reduce positions. Each ladder corresponds to a different maintenance margin rate, when the system determines that the margin is not enough for the current position of the position of the maintenance margin, it will carry out the operation of reducing the number of positions to the next position in the ladder. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://futuresdoc.gitbook.io/help-center/perpetual/untitled-1/ladder-maintenance-margin-rate.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
