#订单类型解析 Trading Type Introduction Why Does Contract Trading Always Lead to Liquidation?

It's not bad luck; it's that you fundamentally don't understand the essence of trading!

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 the principal each time, with three years of no liquidation records. Core formula: Real Risk = Leverage Multiplier × Position Ratio.

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

During the 312 crash in 2024, the common characteristic of 78% of liquidated accounts: losses exceeding 5% but still no stop-loss set. Professional trader's iron rule: 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

Stepwise Positioning Model: First position 10% for trial and error, increase position by 10% of profits. With a principal of 50,000, the first position is 5,000 (10x leverage), adding 500 to the position 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%.
