Why do contracts always get liquidated? It's not bad luck; it's that you fundamentally don't understand the essence of trading! This article condenses ten years of trading experience into low-risk rules that will completely overturn your understanding of contract trading — liquidation is never the market's fault, but a time bomb you buried yourself.

Three major truths that overturn cognition

Leverage ≠ risk: position is the line between life and death

With 100x leverage and using 1% position, actual risk is only equivalent to 1% of spot full position in Bitcoin. A student used 20x leverage trading ETH, investing only 2% of capital each time, with three years of no liquidation record. Core formula: Real risk = Leverage multiple × Position ratio.

Stop loss ≠ loss: the ultimate insurance for the account

In the 312 crash of 2024, the common characteristic of 78% of liquidated accounts: losses exceeded 5% but still did not set stop losses. The iron rule of professional traders: single loss must not exceed 2% of capital, equivalent to setting an "electrical circuit fuse" for the account.

Rolling positions ≠ all in: the correct way to open compound interest

Ladder building model: first position 10% trial error, use 10% of profits to increase position. 50,000 capital initial position 5,000 yuan (10x leverage), increase position by 500 yuan for every 10% profit. When BTC rises from 75,000 to 82,500, the total position only expands by 10%, but the safety margin increases by 30%.

Institution-level risk control model

Dynamic position formula

Total position ≤ (capital × 2%)/(stop loss margin × leverage multiple)

Example: 50,000 capital, 2% stop loss, 10x leverage, maximum position = 50000×0.02/(0.02×10)=5000 yuan

Three-stage profit-taking method

① Take profit 1/3 at 20% profit ② Take profit another 1/3 at 50% profit ③ Move stop loss for remaining position (exit when breaking the 5-day line)

In the 2024 halving market, this strategy increased 50,000 capital to one million during two trends, with a return rate exceeding 1900%

Hedging insurance mechanism

Use 1% of capital to buy Put options when holding positions, tested to hedge 80% of extreme risks. In the black swan event of April 2024, this strategy successfully saved 23% of account net worth.

Deadly trap data empirical evidence

Holding position for 4 hours: liquidation probability increases to 92%

High-frequency trading: average 500 operations per month, 24% capital loss

Profit greed: failure to take profit on time results in 83% profit return

IV. Mathematical expression of trading essence

Expected profit and loss = (Win rate × Average profit) - (Loss rate × Average loss)

When setting a 2% stop loss and 20% profit taking, only a 34% win rate is needed to achieve positive returns. Professional traders achieve annual returns of 400%+ through strict stop losses (average loss of 1.5%) and trend capturing (average profit of 15%).

Ultimate rule:

Single loss ≤ 2%

Annual trading ≤ 20 transactions

Profit and loss ratio ≥ 3:1

70% of the time holding no position waiting

The essence of the market is a probability game; smart traders risk 2% to capture trend dividends. Remember: control losses, and profits will run by themselves. Establish a mechanical trading system to let discipline replace emotional decisions, which is the ultimate answer to sustained profitability.
