The liquidation price of a position is related to your balance, entry price and maintenance margin requirements. As soon as your balance goes below the maintenance margin requirement, the account is liquidated.
The liquidation price moves further away from the entry price as your balance increases. You can ensure that you have enough funds to cover the maintenance margin by allocating more BTC to the sub-account associated with the open position.
You can also reduce the size of any open positions to reduce the likelihood of liquidation. For example, if you are long 100,000 BTC-PERP contracts and close to liquidation, you can sell 60,000 BTC-PERP contracts to reduce your overall position to be long 40,000 BTC-PERP contracts. Reducing the size of a position effectively decreases your maintenance margin.
Finally, you can use stop orders to cut losses before the market reaches the liquidation price. For instance, if you have a short position and the liquidation price is $10,300, you can place a stop order to buy at $10,200 to ensure that the position is not liquidated. Once the mark hit exceeds $10,200, your stop order will be executed and your position will be closed.
