#交易类型入门 Introduction to Trading Types Why Do Contracts Always Liquidate?

It's not bad luck; you simply haven't understood the essence of trading! This article, encapsulating ten years of trading experience and low-risk principles, will completely overturn your perception of contract trading — liquidation is never the market's fault, but a time bomb you planted yourself.

Three Major Truths that Disrupt Understanding

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 operates ETH with 20x leverage, investing only 2% of the capital each time, with three years of zero liquidation record. Core Formula: Actual Risk = Leverage Multiplier × Position Size Ratio.

Stop Loss ≠ Loss: The Ultimate Insurance for Your Account

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

Rolling Position ≠ All-In: The Correct Way to Compound Returns

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