Newbies often ask: What is the most reasonable leverage for perpetual contracts? The core of this question lies in understanding the essence of leverage—it is a tool for amplifying returns, but also a double-edged sword for amplifying risk. As a trader with years of experience in contracts, I will break down the optimal solution from three dimensions: fund efficiency, risk control, and practical strategies.
I. The Underlying Logic of Perpetual Contracts
Unlike futures contracts, perpetual contracts achieve the 'no expiration date' feature through a funding rate mechanism, allowing positions to continue indefinitely. However, the core risk comes from leverage: 1x leverage means 100% margin (no leverage), while 100x leverage only requires 1% margin (risk exposure increases 100 times). Leverage essentially uses margin to leverage positions, and the key lies in matching margin with volatility space.
II. Core Influencing Factors of Leverage Multiples
Fund Utilization Rate Comparison
Taking BTC as an example (current price 30,000U):
100 times leverage: 1 contract margin 300U (30,000U × 1%)
50 times leverage: Margin 600U (30,000U × 2%)
10 times leverage: Margin 3,000U (30,000U × 10%)
Key Point: Low leverage (like 10 times) seems safe but occupies a lot of funds (3,000U only opens 1 contract), high transaction fee proportion (single transaction fee about 10U, accounting for 0.3% of principal); high leverage (100 times) uses 300U to open 1 contract, fund efficiency increases 10 times, and transaction fee proportion drops to 1/10 of 0.3%.
Risk Tolerance Threshold
Leverage multiple = 1 / Margin rate, 100 times corresponds to a 1% margin rate, meaning a 1% price reverse movement will trigger liquidation. However, in practice, a 'buffer zone' must be reserved:
In isolated position mode, it is recommended to have a margin rate ≥ 3% (corresponding to 33 times leverage), reserving 2% volatility space to cope with spikes.
Full position mode requires more conservatism, with a margin rate of 5%-10% (10-20 times leverage) to avoid overall account liquidation.
Market Volatility Adaptability
Volatile Market Conditions (daily volatility ≤2%): Moderately increase leverage (50-100 times) to profit from narrow fluctuations.
Trendy Market Conditions (daily volatility ≥5%): Reduce leverage to 20-30 times, reserve enough margin to withstand pullbacks.
Extreme Market Conditions (Black Swan Events): Recommended leverage ≤ 10 times, or switch to spot mode directly.
III. Practical Leverage Strategy: 'Three-Three Rule' Golden Rule
Basic Position Allocation
Single position opening should not exceed 30% of total funds, corresponding to leverage ≤ 33 times (margin rate 3%).
Example: 10,000U principal, single position margin ≤ 3,000U, can open 10 contracts (300U / contract × 10 = 3000U) under 100 times leverage.
Dynamic Adjustment Mechanism
When profitable: For every 20% gain, reduce leverage by 1 level (like 100 times → 50 times) to lock in profit.
When losing: Upon hitting the 10% stop-loss line, increase the leverage multiple by 1 level (like 50 times → 100 times) to maintain the same position with smaller margin (must ensure sufficient margin).
Risk Hedging Combination
Simultaneously open long and short hedging positions (ratio 1:1), with leverage set at 20 times to lock in interval fluctuation profits.
Before extreme market conditions, switch 50% of the position to 10 times leverage, and convert the remaining 50% to spot, creating a 'balanced offense and defense' portfolio.
IV. Three Major Misconceptions Newbies Must Avoid
'Higher leverage makes liquidation easier' is a fallacy.
Liquidation is essentially 'insufficient margin'. A 100 times leverage with a 3% margin reserved (3 times safety cushion) has stronger anti-drawdown ability than a 20 times leverage with 1% margin (no safety cushion).
Blindly following 'fixed multiples' is not advisable.
The optimal leverage for 5,000U principal and 500U principal is different: the former can open 10 contracts at 30 times leverage (margin 1,500U), while the latter needs 100 times leverage to open 1 contract (margin 50U). The core idea is 'the proportion of margin determines risk'.
Neglecting the cumulative effect of funding rates.
Under high leverage, if holding positions continuously, longs need to pay a daily funding fee of 0.01% (under 100 times leverage, the daily fee for 10 BTC contracts is 3U). Long-term positions need to reserve 10% of funds to cover cost.
V. Ultimate Advice for Ordinary Investors
Small funds (<1000U): Directly use 100 times leverage, open 1-2 contracts per position, keep margin control at 50-100U (5%-10% ratio), accumulate principal using the 'small bets for big returns' strategy.
Medium funds (1,000-10,000U): Use 50 times leverage, margin ratio 3%-5%, daily profit target 50-100U (0.5%-1% of principal), take profit once reached.
Large funds (>10,000U): Leverage ≤ 30 times, divided position operations (≤ 2% of total funds per trade), combined with spot hedging, aiming for 'monthly average stable returns of 15%-20%'
Core Principle: There is no absolute 'reasonable multiple' for leverage, only 'multiples that match your fund size, risk tolerance, and market understanding.' Always remember: Before opening a position, first calculate 'whether you can bear the liquidation loss in the worst-case scenario' before deciding on leverage.
Finally, emphasize: The key to contract profitability is never the leverage multiple, but executing strict stop-loss and take-profit disciplines under the correct leverage. 100 times leverage is not scary; what is scary is using 100 times leverage without 1% risk awareness—this is the true root of liquidation.
