# Margining

Astaria’s margin system is designed specifically for event-linked perpetuals.

Unlike crypto perpetuals, event markets have:

* Prices bounded between `0` and `1`
* Thin liquidity near the extremes
* Discrete resolution into a terminal outcome
* Jump risk that increases near settlement

For that reason, Astaria uses a resolution-aware margin framework.

## Initial Margin

Initial Margin determines how much collateral is required to open a position.

It may include:

* A continuous volatility component
* A jump-risk component
* A size-versus-depth adjustment for large positions

## Maintenance Margin

Maintenance Margin is the minimum account equity required to keep a position open.

If account equity falls below Maintenance Margin, the account becomes eligible for liquidation.

## Leverage

Maximum leverage is dynamic rather than static.

Astaria may reduce available leverage as:

* Resolution approaches
* Market liquidity deteriorates
* Jump risk increases
* The underlying probability moves toward the boundaries of `0` or `1`

## Resolution-Aware Compression

As an event approaches resolution, Astaria can compress maximum leverage toward `1x`.

This is designed to reduce terminal-jump risk and prevent positions from remaining highly levered into final settlement.
