How Perpetual Futures Works
Frequently Asked Questions
How do liquidations work in perpetual futures, and what determines my liquidation price?
Liquidation occurs when position losses consume entire collateral. If you deposit $1,000 with 10x leverage (controlling $10,000 position), a 10% price move against position consumes $1,000 collateral. Any further decline triggers liquidation. Liquidation price depends on entry price, leverage, and collateral: lower leverage = higher price movement tolerance before liquidation. Exchanges calculate liquidation prices precisely shown in position details. When liquidation triggers, exchanges force-close position at market price, often at worse prices than liquidation prices due to market impact. Liquidation cascades occur when many positions liquidate simultaneously—sudden supply/demand imbalance creates sharp price moves liquidating more positions. Understanding liquidation mechanics is critical—many traders lose positions to liquidation, not fundamental reversals.
What are funding rates and how should I use them in trading decisions?
Funding rates are payments between long and short position holders, settling every 1-8 hours (exchange-dependent). Positive rates mean longs pay shorts; negative rates mean shorts pay longs. High positive funding (>0.1% per 8 hours) indicates many traders leveraged long—reveals dangerous imbalance suggesting potential crash when longs liquidate. Low or negative funding indicates balanced positions or short dominance—suggests potential squeeze when shorts cover. Professional traders monitor funding rates as market sentiment indicator: extreme positive funding precedes crashes, negative funding precedes rallies. Use funding rates to identify dangerous imbalances: consider reducing long exposure during unsustainably high positive funding.
Should I use perpetual futures or spot trading for cryptocurrency exposure?
Choice depends on goals and risk tolerance. Spot trading involves buying actual cryptocurrency—simple, no liquidation risk, no funding costs, but requires capital equal to position size. Perpetual futures enable leverage—smaller capital controls larger positions, amplifying returns and losses. For capital-efficient speculation, perpetual futures suit aggressive traders. For long-term holding, spot trading suits risk-averse investors. Professional traders often combine: spot positions for long-term core holdings, perpetual futures for short-term leveraged speculation. Perpetual futures introduce liquidation risk spot trading avoids. Never use leverage you cannot afford to lose—liquidation occurs faster than you can react.
Common Misconceptions About Perpetual Futures
Perpetual futures enable unlimited profit potential—10x leverage means unlimited 10x profits.
Leverage amplifies gains but liquidation limits them. You cannot profit more than available collateral times leverage multiplier. A $1,000 account with 10x leverage on Bitcoin can profit maximum ~$10,000 (entire liquidation if price doubles), not unlimited. More importantly, liquidation prevents capturing entire move—positions liquidate before reaching theoretical maximum profit. Additionally, leverage costs (funding rates, exchange fees) reduce net profits. 10x leverage on 1% moves seems attractive until you realize 1.1% adverse move liquidates you. The leverage profit potential is real but constrained by liquidation mechanics.
Perpetual futures are safer than spot trading because you can't lose more than your collateral.
Both carry loss risks but differently. Spot trading risks losses up to position size (if holding crashes to zero). Perpetual futures risk liquidation at specific prices causing total collateral loss. However, liquidation liquidates at market prices potentially worse than calculated liquidation prices, creating additional losses. Additionally, funding rates represent ongoing costs draining account. Extreme moves can exceed liquidation speeds causing exchange-specific issues. Perpetual futures introduce liquidation timing unpredictability spot trading avoids. Neither is definitively safer—both present risks requiring respect and proper position sizing.
I can hold perpetual futures positions indefinitely without closing because there's no expiration date.
While no expiration exists, several factors force or discourage long-term holding: continuous funding rate costs reduce profitability (sometimes paying 30%+ annual funding rates), exchange liquidation risk persists indefinitely, capital efficiency worsens over time (funding erodes gains), and leverage compounds risks—extended holding increases probability of adverse moves exceeding tolerance. Traders holding perpetual positions weeks/months accumulate substantial funding costs. For true long-term positioning, spot trading is more economical—no funding rates, no liquidation risk. Perpetual futures suit short-to-medium-term positions (days to weeks), not indefinite holdings.
