What is a safe position size for crypto futures trading?

Professional traders typically risk 1-2% of their account balance per trade. With a $10,000 account, that's $100-$200 maximum loss. To calculate position size: divide your max loss by the distance to your stop loss. Example: $100 max loss, stop loss 2% below entry = $100 / 0.02 / entry price = position size in coins. The position size calculator above automates this calculation.

How is the liquidation price calculated in crypto futures?

For isolated margin longs: Liquidation Price ≈ Entry Price × (1 - 1/Leverage + Maintenance Margin Rate). For shorts: Entry Price × (1 + 1/Leverage - Maintenance Margin Rate). At 10x leverage with 0.5% maintenance margin, a long position liquidates approximately 9.5% below entry. Cross margin uses your entire account balance as collateral, so the exact liquidation price depends on your total equity.

What is a funding rate in crypto futures and how much does it cost?

Funding rates are periodic payments between long and short traders on perpetual futures contracts. When positive (common in bull markets), longs pay shorts. Payments typically occur every 8 hours. At 0.01% funding on a $10,000 position: $1 per funding period, $3/day, $90/month. MEXC offers 0% funding fees on select perpetual pairs. OKX uses hourly funding intervals on some pairs instead of 8-hour.

Q: How do I calculate crypto futures P&L?

P&L = (Exit Price - Entry Price) × Position Size for long positions. For short positions, it's reversed: (Entry Price - Exit Price) × Position Size. With 10x leverage, a 1% price move produces a 10% gain or loss on your margin. Example: long 0.1 BTC at $65,000, exit at $68,000. P&L = ($68,000 - $65,000) × 0.1 = $300. Always subtract trading fees from your final P&L.

Q: Which crypto exchange has the lowest futures trading fees in 2026?

MEXC leads with 0% taker fees and 0% funding on select perpetual pairs. Bybit offers -0.01% maker rebates and 0.06% taker fees on futures. OKX charges 0.02% maker and 0.05% taker. Bitget and Phemex charge -0.01%/0.06% maker/taker. For holding positions long-term, MEXC's zero funding fees make it the cheapest option. For active market-making, Bybit and OKX maker rebates can generate income.

💸 How funding works: When rate is positive and you’re long, you pay the rate to shorts. When short with positive rate, you receive it. Funding incentivizes traders to keep perpetual prices close to spot. MEXC offers 0% funding on select pairs.

Frequently Asked Questions

How do I calculate crypto futures P&L? +

P&L = (Exit Price − Entry Price) × Position Size for long positions, reversed for shorts. With leverage of 10×, a 1% move in price produces a 10% gain or loss on your margin. Example: you enter long BTC at $65,000 with 0.1 BTC and exit at $68,000. P&L = ($68,000 − $65,000) × 0.1 = $300. Always subtract trading fees from your P&L — use our fee calculator for exact fee amounts.

What is a safe position size for crypto futures? +

Most professional traders risk 1-2% of their account per trade. With a $10,000 account, that’s $100-$200 maximum loss per trade. The position size calculator above computes this automatically given your entry, stop loss, and leverage. Higher leverage doesn’t increase the size of your position — it reduces the margin required while keeping the nominal exposure the same.

How is crypto futures liquidation price calculated? +

For isolated margin longs: Liquidation Price ≈ Entry × (1 − 1/Leverage + Maintenance Margin Rate). For shorts: Liquidation Price ≈ Entry × (1 + 1/Leverage − Maintenance Margin Rate). At 10× leverage, a long position is liquidated when price drops roughly 8.5-9.5% from entry (depending on maintenance margin and fees). Cross margin is more complex as it uses your entire account balance as collateral.

What is a funding rate and how much does it cost? +

Funding rates are periodic payments between long and short traders on perpetual futures. When the rate is positive (most common during bull markets), longs pay shorts. At a typical 0.01% rate every 8 hours on a $10,000 position, that’s $1 per funding period, $3/day, $90/month. MEXC offers 0% funding fees on select pairs, making it the cheapest platform for holding long-term leveraged positions.
