Cross Margin Overview

In cross margin mode, your futures account's available margin is shared across all positions. When a position incurs floating loss, other available margin in the account acts as a buffer to reduce liquidation risk from short-term volatility. Cross margin improves capital efficiency but also requires sound risk management.

Risk notice: In cross margin mode, extreme moves in any single position can affect overall account risk. Please use leverage responsibly.

Higher capital efficiency

Margin is shared across positions, reducing idle capital and improving overall capital utilization.

More flexible risk control

Losses in one position can be covered by total account margin, reducing the chance of liquidation.

Suited to experienced strategies

Cross margin is better for users who can manage position risk holistically and run more complex strategies.

FAQs
What are perpetual contracts?
Perpetual contracts are USDT-settled derivative contracts with no expiry. You can go long or short to capture price moves, and funding rates keep futures prices aligned with the spot index.
How is trading fee calculated?
Fees are based on the exchange fee schedule, usually including open and close fees. See the official site for exact rates.
What is funding rate? How often is it settled?
Funding rate balances long and short positions. It is typically settled every 8 hours; only positions held at settlement time are charged. See Funding Rate for details.
What is the difference between cross and isolated margin?
In cross margin, available margin backs all positions; in isolated margin, each position is risk-isolated. Cross margin uses capital more efficiently but concentrates risk.
When does liquidation occur?
When maintenance margin ratio falls below the required level, the system liquidates to limit further loss. Liquidation price depends on leverage, position size and margin balance.
Why does futures price differ slightly from spot?
Futures prices are based on a multi-exchange spot index and supply and demand. Short-term differences are normal; funding rates help prices stay in a reasonable range.
Is futures trading on Bitbase safe?
Bitbase aims to provide a stable futures environment through clear rules, risk controls and system reliability. All futures trading carries market risk; please assess and bear risk yourself.
