Liquidation is the forced reduction or closure of a leveraged futures position when account equity can no longer satisfy maintenance requirements. It protects the trading system, not the trader, and should never be used as a planned stop-loss.
What moves liquidation price?
Entry price, position size, leverage, maintenance-margin tier, fees, margin mode and collateral value all matter. Cross margin may draw on more account equity, while isolated margin contains assigned collateral. The platform estimate can change after adding orders or positions.
Mark price versus last price
Many platforms use mark price for liquidation calculations to reduce the impact of isolated abnormal trades. Last price shows the latest execution, while index price reflects external spot markets. Stops may use a different trigger, creating gaps between stop activation and liquidation risk.
Liquidation sequence and costs
When margin becomes insufficient, orders may be canceled and the risk engine can reduce or close exposure. Exact procedures, liquidation fees, insurance funds and auto-deleveraging rules should be read in current contract documentation.
How to reduce the probability
- Use smaller positions and lower leverage.
- Keep a buffer above maintenance margin.
- Set an invalidation exit before liquidation.
- Avoid volatile collateral for correlated trades.
- Monitor funding and open orders.
Adding margin is not always the answer
More collateral moves the estimated liquidation point but increases the capital exposed to a failing thesis. Reassess why the trade is losing before adding funds. The most reliable defense is deciding the maximum loss first and sizing the position so an ordinary stop can exit well before forced liquidation.
Worked liquidation scenario
Two traders take identical $5,000 positions, but one posts $1,000 and the other $250. The second position has less room for adverse movement and reaches maintenance requirements sooner. Adding a volatile collateral asset may change the estimate again. This demonstrates why leverage settings alone cannot describe risk.
Frequently asked questions
Can a stop execute after liquidation?
If liquidation criteria are reached first, the risk engine may act before the stop fills.
Does cross margin prevent liquidation?
No. It can use more equity, potentially exposing a larger account balance.
Is the displayed liquidation price fixed?
No. Fees, funding, margin and other positions can change it.
Final takeaway
Plan exits well before forced closure, keep a margin buffer and size from maximum acceptable loss. Prevention begins before the order is opened.
