Margin Modes

Scape inherits its margining from HyperCore. All Scape markets are isolated margin only. Collateral is confined to a single position, so a loss in one market cannot cascade into another.

​

Initial Margin and Leverage

Leverage can be set to any integer from 1 up to the market maximum. Maximum leverage is tiered: each market defines position-notional tiers, and the maximum steps down as notional grows. Per-market maximums are listed under Commodities. The margin required to open a position is: $$\text{initial margin} = \frac{\text{position size} \times \text{mark price}}{\text{leverage}}$$ Leverage is checked only when opening a position. Afterward, the trader is responsible for monitoring leverage usage to avoid liquidation. Margin can be added or removed post-open, and unrealized P&L counts as additional margin.

​

Maintenance Margin

The maintenance margin is the minimum collateral needed to avoid liquidation. When account equity (collateral plus P&L) falls below it, the position is liquidated. At each notional tier, the maintenance margin rate is half the initial margin rate at that tier’s maximum leverage. Maintenance margin is computed as $$\text{maintenance margin} = \text{MMR} \times \text{notional} - \text{deduction}$$ with per-tier deductions chosen so the schedule is continuous across tier boundaries.

​

Position Limits

Each market caps the position any one account can hold as a fraction of its open-interest cap. The limit graduates with market-maker tier — see Scape’s Market Maker Specification for the schedule.
