Margin is the collateral supporting a leveraged position. Liquidation is the emergency process that reduces or closes the position when available equity is no longer sufficient.
The safest objective is not to calculate how close a trade can operate to liquidation. It is to structure the position so that a planned stop exits first.
What Is Margin?
Margin is the collateral committed to support a leveraged position. Instead of paying the full notional value of the position, the trader deposits only part of it.
The position's profit and loss are still driven by the full exposure. Margin does not reduce the market value of the trade; it only changes how much capital supports that value.
Initial Margin
Initial margin is the minimum collateral required to open a position at the selected leverage.
Higher leverage reduces the initial margin needed for the same position value, but it also reduces the equity buffer available to absorb adverse price movement.
This simplified example does not include fees, maintenance requirements, market-specific tiers, or additional platform rules.
Maintenance Margin
Maintenance margin is the minimum equity required to keep the position open.
As unrealized losses reduce equity, the account moves closer to the maintenance threshold. When the requirement is no longer satisfied, liquidation can begin.
Maintenance requirements can vary by market, position size, leverage limits, and margin tiers.
Margin Balance and Account Equity
Account equity changes as unrealized profit and loss, fees, and funding affect the value supporting open positions.
A position can move closer to liquidation even when no new order is placed. Losses, funding debits, and trading costs can all reduce the available buffer.
What Is Liquidation?
Liquidation is the forced reduction or closure of a leveraged position when equity is no longer sufficient to satisfy the maintenance requirement.
The process exists to prevent an undercollateralized position from continuing indefinitely.
Liquidation is not a planned trade exit. It occurs because the account has lost enough margin capacity that the risk system intervenes.
Why Liquidations Happen
How a Highly Leveraged Position Becomes Vulnerable
Imagine a trader opens a $20,000 position using approximately $1,000 of margin.
The full $20,000 position reacts to market movement. A relatively small move against the trade can therefore create a large loss compared with the $1,000 margin.
How Leverage Changes Liquidation Distance
Higher leverage means less margin supports the same position value.
Because the equity buffer is smaller, a smaller adverse market move can bring the position closer to maintenance requirements.
| Position value | Leverage | Approx. opening margin | Relative buffer |
|---|---|---|---|
| $10,000 | 2× | $5,000 | Larger |
| $10,000 | 5× | $2,000 | Smaller |
| $10,000 | 10× | $1,000 | Much smaller |
| $10,000 | 20× | $500 | Very small |
Mark Price vs Last Price
The last price is the most recent matched trade. The mark price is a separate reference intended for risk calculations.
Liquidation logic commonly relies on mark price rather than the most recent trade. Traders should therefore monitor the correct reference instead of assuming that only the visible candle close matters.
Last price
The price of the most recent executed trade.
Mark price
A reference used for margin, unrealized P/L, and liquidation calculations.
Cross Margin vs Isolated Margin
Cross margin
- • Shares eligible collateral across positions.
- • Can improve capital efficiency.
- • One losing position can affect more account equity.
- • Requires portfolio-level monitoring.
Isolated margin
- • Allocates collateral to one position.
- • Separates that position from other isolated trades.
- • Makes allocated exposure easier to see.
- • May require active margin management.
Long vs Short Liquidation
Long and short positions are liquidated in opposite directions.
| Position | Adverse move | Squeeze risk |
|---|---|---|
| Long | Price falls | Long liquidations can accelerate selling |
| Short | Price rises | Short liquidations can accelerate buying |
How Funding and Fees Affect Margin
Funding payments and trading fees reduce the net equity supporting the position.
A trade that appears safe based only on entry and liquidation price can move closer to risk over time if funding remains unfavorable.
Frequent entries and exits also accumulate fees, which matters more when the account is small or leverage is high.
Why a Stop Loss Must Come Before Liquidation
A stop loss defines where the trade idea becomes invalid. The stop should normally be reached before liquidation becomes relevant.
A liquidation price describes when the margin system may act. It does not describe where the trade thesis is logically wrong.
Stop-loss exit
Planned, risk-based, and connected to invalidation.
Liquidation exit
Forced, margin-driven, and often associated with severe loss.
Position Sizing Must Come Before Leverage
The safer process starts with the acceptable account loss and logical stop distance.
Position size is then calculated from those two values. Leverage is selected afterwards to determine how much margin is required.

Frequently Asked Questions
What is margin in perpetual futures trading?
Margin is the collateral supporting a leveraged position. It allows a trader to control a position larger than the capital directly committed to that trade.
What is initial margin?
Initial margin is the minimum collateral required to open a position at the selected leverage.
What is maintenance margin?
Maintenance margin is the minimum equity required to keep a position open. Falling below the requirement can trigger liquidation.
What causes liquidation?
Liquidation occurs when the account or position no longer has enough equity to satisfy maintenance-margin requirements.
Does high leverage move the market against me?
No. High leverage does not influence market direction. It makes the same price movement have a larger effect on the margin supporting the position.
Why does higher leverage reduce liquidation distance?
Higher leverage means less margin supports the same position value, so a smaller adverse move can consume the available equity buffer.
What is the difference between mark price and last price?
The last price is the most recent traded price. The mark price is a reference used for risk calculations, unrealized profit and loss, and liquidation logic.
Can a position be liquidated before the chart touches the last-price level I expected?
Yes. Liquidation calculations may use mark price rather than the last traded price, so traders should monitor the correct reference.
What is cross margin?
Cross margin shares available collateral across eligible cross-margin positions, which can improve capital efficiency but also connects the risk of multiple positions.
What is isolated margin?
Isolated margin restricts allocated collateral to one position, helping separate that position's risk from other isolated positions.
Can I lose more than the margin assigned to a position?
The answer depends on margin mode, account equity, platform rules, liquidation execution, and extreme market conditions. Traders should not assume the displayed margin is always the maximum possible account impact.
Is liquidation the same as a stop loss?
No. A stop loss is part of a planned trade exit. Liquidation is an emergency mechanism that acts when margin becomes insufficient.
Can adding margin prevent liquidation?
Adding margin can increase the equity buffer and move the liquidation threshold, but it also commits more capital to a losing position and does not repair a weak trade thesis.
Do funding payments affect liquidation risk?
Yes. Funding and trading fees can reduce account equity over time, which can move the position closer to maintenance requirements.
What is the safest way to reduce liquidation risk?
Use conservative leverage, calculate position size from the stop distance, place a stop before liquidation, maintain sufficient collateral, and reduce exposure during volatile conditions.
Liquidation Should Never Be the Plan
Margin makes leveraged trading possible, but it also creates the conditions for forced closure.
A disciplined trader defines invalidation first, calculates position size from acceptable loss, chooses conservative leverage, and keeps the stop well before liquidation.
