margin and settlement

cross-margin system

durian follows a cross-margin model designed to maximize capital efficiency. all accounts are cross-margined by default, which means your entire account balance serves as collateral for all open positions. profits from one position can offset losses from another, allowing for more efficient use of your capital.

to manage risk and ensure smoother order execution, you can only use up to 90% of your total funds for positions. this buffer helps protect against immediate liquidations during high volatility and ensures you have room for fees and funding payments.

settlement details

all markets are denominated and settled in usdt. this includes fees, funding payments, and pnl. if you have usdt in your account, all settlements will be automatically debited from your usdt balance.

risk management and leverage

leverage controls

maximum leverage is set at the trading pair level, with different trading pairs potentially having different maximum leverage limits. you can choose your desired risk level by setting leverage when placing an order.

lower leverage means you'll need to commit more of your balance as margin to open a position of a specific size, but your position will be less susceptible to liquidation during price fluctuations. higher leverage allows you to open larger positions with less capital, but increases the risk of liquidation if the market moves against you.

isolating risk

if you want to isolate risk between different strategies or asset classes, you can create additional accounts. each account is completely segregated from others, meaning losses in one account cannot affect balances in another. this provides a way to effectively isolate risk while maintaining the benefits of cross-margin within each individual account.

fees and liquidations

funding and fees

perpetual futures contracts use a funding mechanism to keep prices aligned with the underlying market. funding is periodically exchanged between long and short position holders, and all funding payments are automatically settled in usdt.

all trading fees are denominated and collected in usdt. fees are deducted directly from your available balance.

liquidation process

when the value of your positions falls below maintenance margin requirements, the system will begin liquidating your positions. liquidations are executed at market prices. you will still receive durian points for both opening and closing (liquidation) of positions.

the cross-margin system automatically shares margin across all positions within the same account. always monitor your account's overall health rather than individual positions. remember that high leverage significantly increases both potential profits and losses.
