Your entire Withdrawable Balance can be withdrawn at any time, provided it is above the minimum withdrawal size as stated on the withdrawals page. Available Balance, which includes unrealised profits, cannot be withdrawn until it is realised. If you hold a Cross position, withdrawing from your Withdrawable Balance reduces available margin and affects your liquidation price. See the Margin Terms & Definitions article for more information on Withdrawable Balance.
What is the difference between Withdrawable Balance and Available Balance?
Understanding the distinction between Withdrawable Balance and Available Balance is essential for managing withdrawals on BitMEX. Your Withdrawable Balance represents the portion of your account funds that can be withdrawn immediately. Your Available Balance, on the other hand, includes unrealised profits from open positions, and these funds cannot be withdrawn until the profits are realised by closing the relevant positions.
Available Balance (Cross) = Margin Balance - Order Margin - Position Margin
Available Balance (Isolated) = Wallet Balance - Initial Margin/Order Cost - Order Margin
See the Margin Terms & Definitions article for a full explanation of how these balance types are calculated.
How do withdrawals affect Cross-margin positions?
When you withdraw funds while holding a Cross-margin position, the withdrawal reduces the total margin available to that position. Cross-margin positions use the entire Withdrawable Balance in your account as collateral, so any reduction in the balance directly impacts the margin backing the position. As a result, the liquidation price of the Cross-margin position moves closer to the current market price.
Before making a withdrawal with an open Cross-margin position, review the potential impact on your liquidation price. A withdrawal that significantly reduces your available margin could increase the risk of liquidation if the market moves against your position. BitMEX displays the current liquidation price for each position on the trading interface, allowing you to assess the effect before confirming a withdrawal.
Traders using Isolated-margin positions are not affected in the same way, because Isolated-margin positions have a fixed amount of margin assigned to them, separate from the Withdrawable Balance. Withdrawing funds does not change the margin or liquidation price of an Isolated-margin position.
