Why do contracts always get liquidated?

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

Three major truths that overturn understanding

Leverage ≠ Risk: Position size is the life-or-death line

Using 1% position size 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 size ratio.

Stop-loss ≠ Loss: The ultimate insurance for accounts

During the 2024 March 12 crash, 78% of liquidated accounts shared a common characteristic: losses exceeded 5% but still did not set stop-losses. Professional traders' iron rule: a single loss should not exceed 2% of the capital, which is equivalent to setting a "circuit breaker fuse" for the account.

Rolling positions ≠ All-in: The correct way to compound

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