How to Calculate Liquidation Price on OKX Futures? Understanding Liquidation Conditions

Understanding Liquidation in Unified Accounts

Under OKX's unified account system, futures liquidation is primarily determined by margin ratio. When a position's margin ratio falls to ≤100%, partial liquidation or full liquidation may occur.

Key Points:

• Traders can use the built-in "Calculator" on the contract trading page to estimate liquidation prices
• For multiple open positions in a unified account, estimated liquidation prices may differ from actual execution prices

• OKX employs graded liquidation to minimize market impact:

  1. Automatic position reduction triggers first
  2. System checks if reduced position meets new tier's maintenance margin
  3. Cycle continues until full liquidation if necessary

Margin Ratio Formulas

1. Single-Currency Margin Mode (Cross-Margin)

Margin Ratio = 
(Currency Balance + P&L - Pending Orders - Option Buys - Isolated Margin Requirements - Order Fees) / 
(Maintenance Margin + Liquidation Fees)

2. Cross-Currency Margin Mode (Cross-Margin)

Margin Ratio = 
Effective Margin / 
(Maintenance Margin + Reduction Fees)

3. Isolated Margin Mode

Long Positions:

Margin Ratio = 
[Position Value - (Debt + Interest)/Mark Price] / 
(Maintenance Margin + Fees)

Short Positions:

Margin Ratio = 
[Position Value - |Debt + Interest| * Mark Price] / 
(Maintenance Margin + Fees)

• Create unnecessary losses
