OKX to change initial margin requirement (IMR) for futures under one-way mode in spot and futures and multi-currency account modes

Date de publication : 24 oct. 2024Lecture de 3 min

To improve your trading experience, OKX will be implementing changes to the calculations of the initial margin requirement (IMR) for futures under one-way mode in spot and futures and multi-currency modes. The adjustment will take place from 8:00 am UTC on October 31, 2024 to 8:00 am UTC on November 8, 2024.

Margin requirement for positions and open orders under one-way mode

Under the new calculation, you will only be charged the highest margin required for either the buy or sell side.

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

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

This change will generally decrease the margin required for futures positions and orders when you have orders of opposing directions.

Futures order loss

In addition to the margin required to open a position, futures order loss will now be factored into order cost calculations. In futures trading, when the order price deviates from the mark price, the system will calculate order loss. For example, when your buy order price is higher than the mark price or your sell order price is lower than the mark price, a floating loss will occur if the order is executed. To protect your assets and ensure platform safety, OKX includes order loss as a part of the cost required to open a position to prevent liquidation.

  • 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)])

For market orders, the platform uses an estimated fill price as the order price.
