#交易类型入门 Why does playing contracts always lead to liquidation?

It's not bad luck; it's that you fundamentally 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 planted yourself.

Three Major Truths That Change 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 used 20x leverage to trade ETH, investing only 2% of capital each time, with three years of zero liquidation records. Core formula: Actual Risk = Leverage Ratio × Position Size.

Stop Loss ≠ Loss: The Ultimate Insurance for Your Account

During the 312 market crash in 2024, a common characteristic of 78% of liquidated accounts: losses exceeded 5% but still did not set a stop loss. Professional traders' iron rule: single losses must not exceed 2% of capital, equivalent to setting a 'circuit fuse' for the account.

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

Stair-step Positioning Model: First position 10% for trial error, then increase position by 10% of profits. With a capital of 50,000, the first 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 only expands by 10%, but the safety margin increases by 30%.
