一覽

Perpetual futures are leverage-enabled derivative contracts that track spot prices but never expire (unlike quarterly futures). You can be long or short indefinitely, paying/receiving a funding rate every 8 hours. Key challenges: funding rate swings (can be 0.01% to 1% per day, costing/earning fortunes), mark-to-market margin, forced liquidation when leverage depletes capital. Popular on Binance, Bybit, Deribit. Mastery takes 4-6 months. Professional traders earn 15-25% premium because perpetual trading requires discipline (risk control, funding rate arbitrage) and most retail traders lose money.

什麼是 Derivatives Perpetual Futures

Perpetual futures (or perpetuals) are cryptocurrency derivative contracts that track spot prices but have no expiration date. You buy/sell 1 BTC perpetual at 10x leverage, controlling $65,500 of exposure with $6,550 of capital. Unlike quarterly futures (that expire), perpetuals stay open indefinitely. To keep the perpetual price close to spot, a funding rate is exchanged every 8 hours between longs and shorts. If perpetuals are trading above spot (demand > supply), longs pay shorts, incentivizing new shorts and discouraging new longs (price falls). This mechanism keeps perpetuals synced with spot.

❓ 常見問題

What's a funding rate and why does it matter?
Funding rate = payment between traders to keep perpetual price in line with spot price. If perpetual is trading above spot, longs pay shorts (rate is positive). You're long, rate is 0.1% per 8 hours = 1.2% per day = 30%+ annualized cost. High funding rates = expensive to hold positions. Traders exploit: long at high funding rate = earn funding, hedge with short spot (arbitrage).
How is mark price different from index price?
Index price = average spot price across exchanges (BTC/USD might be $65,500). Mark price = fair value estimate for the perpetual (usually close to index, but can deviate during extreme volatility). Your position is marked at mark price (not index). This prevents liquidations from flash crashes.
When do I get liquidated?
When maintenance margin falls below 0%. Example: $100K account, $1M position (10x leverage), 2% adverse move = -$20K loss = $80K remaining capital = 8% maintenance margin (safe). 5% move = -$50K loss = $50K remaining = 5% maintenance margin (warning). 6% move = -$60K loss = liquidation engine closes position at market price (slippage possible).
Can I use perpetuals for hedging?
Yes. Own 1 BTC spot, short perpetuals 1 BTC. Spot falls, perp short gains offset. Hedge cost: funding rate and trading fees. If funding rate is 0.05% per 8h, cost is 0.15%/day = 55%/year. Only makes sense if you expect spot downside and funding is cheap.
What's the difference between isolated and cross margin?
Isolated margin: each position has separate capital, separate liquidation price. One position blows up, others survive. Cross margin: all positions share capital. One position blows up, it eats capital from others, risking cascade liquidation. Isolated is safer for learning.
