OKX Adjusts Initial Margin Requirement (IMR) for Futures in One-Way Mode

To enhance your trading experience, OKX will modify how initial margin requirements (IMR) are calculated for futures contracts operating under one-way mode in both spot and futures and multi-currency account configurations. These updates aim to optimize margin efficiency while maintaining platform stability.

Key Implementation Timeline

Start: October 31, 2024 (8:00 am UTC)
End: November 8, 2024 (8:00 am UTC)

Revised Margin Calculation for One-Way Mode Positions

Under cross margin, the new system charges only the highest margin needed between opposing buy/sell orders, reducing overall requirements:

Long Positions

Max [(Position notional value + Buy order value), (Sell order value – Position notional value)] / Leverage

Short Positions

Max [(Buy order value – Position notional value), (Position notional value + Sell order value)] / Leverage

Futures Order Loss Integration

OKX now factors order loss into position costs to mitigate liquidation risks when order prices deviate from mark prices:

USDT-Margined Contracts

Buy Order Loss:
Abs (Contract size × |Number of contracts| × Multiplier × Min [0, (Mark price – Order price)])
Sell Order Loss:
Abs (Contract size × |Number of contracts| × Multiplier × Min [0, (Order price – Mark price)])

Crypto-Margined Contracts

Buy Order Loss:
Abs (Contract size × |Number of contracts| × Multiplier × Min [0, (1 / Order price – 1 / Mark price)])
Sell Order Loss:
Abs (Contract size × |Number of contracts| × Multiplier × Min [0, (1 / Mark price – 1 / Order price)])

Note: Market orders use estimated fill prices for calculations.
