What Are Maximum Position, Maximum Leverage, and Initial Margin Ratio?

• Maximum Leverage depends on the nominal value of the position — the larger the position, the lower the allowed leverage. You can adjust the leverage according to your needs. The size of all positions is calculated based on the nominal value of the contract. Therefore, the initial margin is determined by the leverage you choose.

• Note: You should select the leverage before opening a position (and meet the initial margin requirements). The higher the leverage, the lower the nominal value you are allowed to open; the lower the leverage, the higher the nominal value you are allowed to open.

The system will display the maximum allowed position size for different leverage levels, as shown in the diagram below:

What Is Maintenance Margin?

Maintenance margin is a critical term in trading, especially in futures trading. It refers to the minimum amount of margin that a user must maintain in their account to keep their leveraged positions. The maintenance margin is calculated based on the level of the nominal value of the user's position.

Maintenance Margin = Nominal Value of Position * Maintenance Margin Rate - Maintenance Margin Amount

• Refer to leverage and margin to get the latest information about the nominal value of the position, maximum leverage, corresponding maintenance margin rate, and maintenance amount.
• The maintenance margin is calculated according to the tier of the nominal value of the position. This means that regardless of the leverage level you choose, the calculation method for maintenance margin remains the same for the same nominal value tier. Increasing the nominal value tier does not affect the leverage for previous tiers. The larger the position, the higher the maintenance margin rate.
• At BitMart Exchange, the maintenance margin is typically half of the initial margin.
• It is important to note that the maintenance margin directly impacts the liquidation price. To avoid auto-deleveraging, it is strongly recommended that you close your position before your collateral falls below the maintenance margin.

Maintenance Margin Rate

• The maintenance margin calculation is set by "tiers". Regardless of your leverage adjustments, the method of calculating the maintenance margin does not change. Even if there are changes in the tiers, it will not affect the leverage of previous tiers. To avoid automatic liquidation, you should close your position before your collateral falls below the maintenance margin.
• If your position is in cross margin mode, you can use the [Adjust Leverage] button to increase or decrease the leverage.
• If your position is in isolated margin mode, you cannot decrease the leverage.
