#交易对 Trading Type Introduction: Why Do Contracts Always Liquidate?

It's not bad luck; it's that you don't understand the essence of trading! This article, condensing 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, but rather a time bomb you planted yourself.

Three Major Truths That Challenge Conventional Wisdom

Leverage ≠ Risk: Position Size is the Lifeline

Using 1% position size with 100x leverage, the actual risk is only equivalent to 1% of a fully invested spot position. A certain student operated ETH with 20x leverage, only investing 2% of the principal each time, with three years of no liquidation records. Core formula: Real Risk = Leverage × Position Ratio.

Stop-Loss ≠ Loss: The Ultimate Insurance for Your Account

During the 312 crash of 2024, 78% of liquidated accounts shared a common trait: losses exceeded 5% without setting a stop-loss. The iron rule for professional traders: a single loss must not exceed 2% of the principal, equivalent to setting a "circuit fuse" for the account.

Rolling Positions ≠ All-In: The Correct Way to Compound

Ladder Positioning Model: First position 10% trial and error, add 10% of profits to the position. With a principal of 50,000, the first position is 5,000 (10x leverage), adding 500 for every 10% profit. When BTC rises from 75,000 to 82,500, the total position only expands by 10%, but the safety margin increases by 30%.
