#交易流动性 Trading Type Introduction: Why Do Contracts Always Liquidate?

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

Three Major Truths That Disrupt Understanding

Leverage ≠ Risk: Position Size is the Lifeline

Using 1% position 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, investing only 2% of the principal each time, with three years of zero liquidations. Core Formula: Real Risk = Leverage Multiplier × Position Ratio.

Stop Loss ≠ Loss: The Ultimate Insurance for the Account

During the 312 crash in 2024, 78% of liquidated accounts shared a common feature: losses exceeded 5% without setting stop losses. Professional trader's iron rule: single transaction losses must not exceed 2% of the principal, equivalent to setting an "electrical circuit fuse" for the account.

Rolling Positions ≠ All In: The Correct Way to Compound

Step-by-Step Position Building Model: Start with 10% for trial, then add positions with 10% of the profits. With a principal of 50,000, the initial position is 5,000 yuan (10x leverage), adding 500 yuan for every 10% profit. When BTC rises from 75,000 to 82,500, the total position only expands by 10%, but the margin of safety increases by 30%.
