Cross-margin mode and isolated-margin mode are the two primary margin management modes in LBank Futures trading, each with distinct risk profiles and applicable scenarios.

Isolated-Margin Mode

In isolated-margin mode, only a portion of the funds in the futures account is used as margin for a single position. The initially locked margin represents the maximum potential loss for that position. Upon forced liquidation, only the margin allocated to that position is deducted, leaving the remaining available balance in the account unaffected.

  1. Advantages: Complete risk isolation; losses in one position do not impact other positions or the account balance.

  2. Disadvantages: Lower capital efficiency; margin cannot be shared across positions.

Example (BTC Futures, 20x leverage):

Account Balance

100 USDT

Position Margin

10 USDT

Position Size

0.02 BTC 

(assuming BTC price = 10,000 USDT, position value = 200 USDT)

Leverage

20x

Liquidation Price

Entry Price × (1 - 1/Leverage) = 10,000 × (1 - 1/20) = 9,500 USDT

Actual Liquidation Trigger Price

(incl. fees & slippage)

≈10,000 USDT

Loss Upon Liquidation

10 USDT

Remaining Account Balance

90 USDT

Explanation: Upon liquidation, only the 10 USDT margin for this position is lost; the remaining funds remain secure.

Cross-Margin Mode

In cross-margin mode, the entire available balance in the futures account serves as margin for all positions. This reduces the risk of early forced liquidation but exposes the full account balance to potential loss.

  1. Advantages: High capital efficiency; flexibly supports all positions and prevents premature liquidation of individual positions.

  2. Disadvantages: All positions share the same margin pool; a sharp adverse move in one direction may result in total account loss.

Example (BTC Futures, 20x leverage):

Account Balance

100 USDT

Available Margin

100 USDT(full amount utilized)

Position Size

0.2 BTC (assuming BTC price = 10,000 USDT, position value = 2,000 USDT)

Leverage

20x

Liquidation Price

Entry Price × (1 - 1/Leverage × Margin Ratio) ≈ 10,000 × (1 - 1/20) = 9,500 USDT

Actual Liquidation Trigger Price (considering full margin)

≈2,000 USDT (actual depends on platform maintenance margin rate)

Loss Upon Liquidation

100 USDT

Remaining Account Balance

0 USDT

Explanation: In cross-margin mode, the entire account is at risk; a significant price drop can wipe out the full balance.
