Calculating margin requirements for perpetual trading on CoinUnited.io.

Updated over a year ago

The margin requirement in Futures trading includes:

  • The margin allocated to existing positions;

  • The margin required to open orders.

Please note that margin is not required when placing stop loss orders or take profit orders on existing positions.

CoinUnited implemented a solid risk control system and liquidation model to support high leverage trading by adopting the Maintenance Margin model.

For more details about leverage and notional value, please refer to the Trading Rules page.

Notional value of existing positions:

  • Notional Value = Position Size (calculated in coin) * Mark Price

Order value of open orders:

  • Limit Order Value = Order Size (calculated in coin) * Limit Price

  • Stop Market Order Value = Order Size (calculated in coin) * Trigger Price

For example:

  • You have an open long ETHUSDT position of 8,000 USDT notional value (5 ETH, mark price 1,600 USDT);

  • You have an existing open long limit order of 2 ETHUSDT, with a limit price set at 1,000 USDT;

  • You have an existing open short stop market order of 3 ETHUSDT, with a limit price set at 1,500 USDT.

  • Total Notional Value of ETHUSDT = 8,000 + 2 * 1,000 + 3 * 1,500 = 14,500 USDT

  • At 400x leverage, the required margin for the position and open orders of ETHUSDT

    = 25 + (14,500 - 10,000) * 0.25%

    = 36.25 USDT

What are maximum notional value, maximum leverage, and Margin%?

The maximum amount of leverage available depends on the notional value of your position — the larger the position, the lower the leverage. You can adjust the leverage according to your risk preference, and all position sizes are calculated based on the contract's notional value. Thus, the Initial Margin is determined by the leverage you selected.

Initial Margin Requirement: When a new order is to be placed, the system will conduct an initial margin check.

  • There will be initial margin checks for open position orders.

  • There is no margin check for a close-position orders, such as market close, take profit and stop loss orders


Open order will be successfully placed when:

  • Available Balance >=0 after the order is placed.

  • Total Account Value >= Maintenance Margin (USD) after the order is placed.

For more details about leverage and notional value, please refer to the Trading Rules page.
