#交易类型入门 Why do contract trades always lead to liquidation?

It's not bad luck; it's that you fundamentally don't understand the essence of trading! This article condenses ten years of trading experience into low-risk principles that will completely overturn your understanding of contract trading — liquidation is never the market's fault, but rather a time bomb you set yourself.

Three major truths that overturn perceptions

Leverage ≠ Risk: Position size is the lifeline

Using 1% position with 100x leverage, the actual risk is only equivalent to 1% of a full spot position. A student operated ETH with 20x leverage, investing only 2% of the capital each time, with three years and no liquidations. Core formula: Actual risk = Leverage multiplier × Position ratio.

Stop-loss ≠ Loss: The ultimate insurance for your account

In the 312 crash of 2024, 78% of liquidated accounts shared a common trait: losses exceeded 5% without setting a stop-loss. A professional trader's iron rule: single trade losses must not exceed 2% of the capital, which is equivalent to setting a "circuit breaker" for the account.

Rolling position ≠ All-in: The correct way to unlock compound interest

Step-wise position building model: First position 10% for trial and error, adding 10% of profits to the position. With a capital of 50,000, the first position is 5,000 (10x leverage), adding 500 to the position every time profits increase by 10%. When BTC rises from 75,000 to 82,500, the total position only increases by 10%, but the safety margin increases by 30%.

Institution-level risk control model

Dynamic position formula

Total position ≤ (Capital × 2%) / (Stop-loss range × Leverage multiplier)

Example: With 50,000 capital, 2% stop-loss, and 10x leverage, the maximum position calculated is = 50000 × 0.02 / (0.02 × 10) = 5000.

Three-stage profit-taking method

① Close 1/3 at 20% profit ② Close another 1/3 at 50% profit ③ Move stop-loss for remaining position (exit if below the 5-day line)

In the 2024 halving market, this strategy allowed a capital of 50,000 to grow to a million during two trends, with a return rate exceeding 1900%.

Hedging insurance mechanism

When holding positions, use 1% of the capital to buy Put options, which can hedge against 80% of extreme risks. In the April 2024 black swan event, this strategy successfully saved 23% of account net worth.

Data evidence of deadly traps

Holding a position for 4 hours: Liquidation probability increases to 92%

High-frequency trading: Monthly average of 500 operations loses 24% of capital

Greed for profit: Failure to take timely profits results in an 83% account drawdown

Fourth, the mathematical expression of the essence of trading

Expected profit = (Win rate × Average profit) - (Loss rate × Average loss)

When setting a 2% stop-loss and 20% take-profit, only a 34% win rate is needed to achieve positive returns. Professional traders achieve an annualized return of over 400% by strictly enforcing stop-losses (average loss of 1.5%) and capturing trends (average profit of 15%).
