Understanding Position Margin on Bybit

Position margin on Bybit refers to the amount of funds allocated to open and maintain a leveraged trading position. This margin acts as collateral to ensure that traders can meet potential losses from their positions. When you enter into a futures or perpetual contract trade on Bybit, part of your available balance is set aside as position margin, which remains locked for the duration of the trade. The size of this margin depends on several factors, including leverage, entry price, and the quantity of the contract.

This margin is distinct from your wallet balance or available balance. While your wallet balance reflects all funds in your account, the position margin is specifically dedicated to active trades. If the market moves against your position and losses accumulate, Bybit may initiate a liquidation process once the equity in your position drops to the maintenance margin level. Understanding how position margin works is essential to managing risk effectively on the platform.

Difference Between Initial and Maintenance Margin

On Bybit, two types of margin are critical: initial margin and maintenance margin. The initial margin is the percentage of the total position value required to open a trade. For example, if you use 10x leverage, the initial margin would be 10% of the position’s notional value. This amount is drawn from your available balance and becomes your position margin.

The maintenance margin, on the other hand, is the minimum amount of margin required to keep the position open. It serves as a buffer against sudden price movements. If losses reduce your position margin below this threshold, a margin call occurs, potentially leading to liquidation. Bybit automatically calculates both values based on the contract type, leverage, and market conditions. Traders must monitor these levels closely to avoid unexpected closures of their positions.

How to View Your Position Margin on Bybit

To check your position margin on Bybit, log in to your account and navigate to the derivatives trading interface. Select either USDT Perpetual, Inverse Perpetual, or Futures depending on the contract you're trading. Once you have an open position, locate the "Positions" tab at the bottom of the screen.

In this section, you will see detailed information about each active trade. Key fields include:

• Size: The quantity of the asset held in the position
• Entry Price: The average price at which the position was opened
• Leverage: The selected leverage ratio
• Position Margin: The exact amount of funds currently committed to maintaining the trade

This position margin updates dynamically with changes in mark price and funding rates. You can also view the liquidation price, which is directly influenced by your current position margin and maintenance requirements.

Adjusting Leverage and Its Impact on Position Margin

Bybit allows users to adjust leverage before or after opening a position, which directly affects the position margin. Increasing leverage reduces the amount of margin needed to open a position, while decreasing leverage increases it. However, changing leverage does not alter the total notional value of your position—only the margin allocation.

To modify leverage:

• Click on the leverage selector located near the order entry panel
• Choose a new leverage value from the dropdown menu
• Confirm the change when prompted

After adjustment, the position margin recalculates instantly. For instance, switching from 5x to 20x leverage on a $10,000 position reduces the required position margin from $2,000 to $500. Keep in mind that higher leverage increases liquidation risk due to smaller price movements triggering margin calls.

Adding or Reducing Margin Manually

Traders can manually increase or decrease the position margin on existing positions to manage risk exposure. This feature is especially useful during volatile markets to prevent liquidation.

To add margin:

• Go to the "Positions" tab
• Find the relevant open position
• Click the "Add Margin" button
• Enter the desired amount to transfer from your wallet balance
• Confirm the transaction

To reduce margin:

• Locate the same "Positions" tab
• Select "Reduce Margin"
• Input the amount you wish to withdraw
• Approve the withdrawal

Note that you cannot reduce the position margin below the maintenance margin requirement. Attempting to do so will trigger an error message. These adjustments help fine-tune your risk profile without closing the entire position.

Funding Rate and Its Indirect Effect on Position Margin

While funding rates do not directly deduct from your position margin, they influence your overall position equity. On Bybit, funding is exchanged between long and short traders every 8 hours. If you hold a long position and the funding rate is positive, you pay funding to short holders. This payment comes out of your available balance or position equity.

Over time, repeated funding payments can erode the effective value of your position margin, bringing it closer to the maintenance level. Conversely, receiving funding increases your equity slightly. Although funding is not subtracted from the displayed position margin, its cumulative effect impacts your liquidation risk. Monitoring upcoming funding times and rates helps anticipate these shifts.

Frequently Asked Questions

Can I use my position margin for other trades?

No, position margin is locked and cannot be used for opening new positions or placing orders. Only your available balance outside of active positions can be utilized for additional trades.

What happens to my position margin if my trade is liquidated?

Upon liquidation, the position margin is used to cover losses up to its full value. If the loss exceeds the margin, the insurance fund typically covers the deficit. In most cases, the entire position margin is lost during liquidation.

Is position margin the same across all Bybit products?

No, position margin calculations vary between USDT-margined contracts, inverse contracts, and quarterly futures. Each product has different margining rules based on denomination and settlement asset.

Does isolated margin mode affect position margin differently than cross margin?

Yes, in isolated margin mode, the position margin is fixed and limited to the amount allocated. In cross margin mode, the system can use your entire wallet balance to support the position, making the effective position margin variable.
