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

It's not bad luck; you simply don't understand the essence of trading! This article, encapsulating 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 set yourself.

Three Major Truths to Overturn Your Understanding

Leverage ≠ Risk: Position Size is the Lifeline

Using 1% position size with 100x leverage results in actual risk equivalent to 1% of a full spot position. A certain student operated ETH with 20x leverage, only investing 2% of the principal each time, and has maintained a zero liquidation record for three years. Core Formula: Actual Risk = Leverage Factor × Position Ratio.

Stop Loss ≠ Loss: The Ultimate Insurance for Your Account

During the March 12, 2024, crash, 78% of liquidated accounts shared a common trait: losses exceeding 5% without setting stop losses. A professional trader's rule: single trade losses must not exceed 2% of the principal, which is equivalent to setting a "circuit fuse" for the account.

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

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