Why does #交易类型入门 always get liquidated in contracts?
It's not bad luck; you simply don't understand the essence of trading! This article, condensing ten years of trading experience into low-risk principles, will completely overturn your understanding of contract trading—liquidation is never the market's fault, but a time bomb you set 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 a full spot position of 1%. A certain student operated ETH with 20x leverage, investing only 2% of the capital each time, with three years of zero liquidations. Core Formula: Real Risk = Leverage Multiplier × Position Ratio.
Stop Loss ≠ Loss: The Ultimate Insurance for Accounts
During the 312 crash in 2024, 78% of liquidated accounts shared a common trait: they did not set stop losses despite losses exceeding 5%. Professional traders' iron rule: a single loss should not exceed 2% of the capital, equivalent to setting a "circuit fuse" for the account.
Rolling Positions ≠ All In: The Correct Way to Compound
Stair-step Positioning Model: Start with a 10% trial position, then add 10% of the profits to the position. Starting capital of 50,000, initial position of 5,000 (10x leverage), add 500 for every 10% profit. When BTC rises from 75000 to 82500, the total position only increases by 10%, but the safety margin increases by 30%.
Institution-level Risk Control Model
Dynamic Position Formula
Total Position ≤ (Capital × 2%) / (Stop Loss Range × Leverage Multiplier)
Example: For 50,000 capital, 2% stop loss, and 10x leverage, the maximum position calculated is = 50000 × 0.02 / (0.02 × 10) = 5000.
Three-stage Profit Taking Method
① Close 1/3 at 20% profit ② Close 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 the capital of 50,000 to a million during two trends, with a return rate exceeding 1900%.
Hedging Insurance Mechanism
When holding positions, use 1% of the capital to purchase Put options, which can hedge 80% of extreme risks. In the April 2024 black swan event, this strategy successfully saved 23% of the account's net value.
Deadly Trap Empirical Data
Holding a position for 4 hours: the probability of liquidation rises to 92%
High-frequency trading: averaging 500 operations per month results in a 24% capital loss
Profit Greed: Failure to take profits in time leads to an 83% profit drawdown in accounts.
Four, Mathematical Expression of Trading Essence
Expected Profit = (Win Rate × Average Profit) - (Loss Rate × Average Loss)
When setting a 2% stop loss and a 20% take profit, only a 34% win rate is needed to achieve positive returns. Professional traders achieve annual returns of over 400% by strictly setting stop losses (average loss of 1.5%) and capturing trends (average profit of 15%).
