When trading contracts, do you think opening a full position is safer? I have a friend who turned $3,000 into $12,000 in half a month last year, thinking he had found the way.
One night, he used a full position with 10x leverage to go long on Ethereum, with $9,800 in his account, and he bet $9,000.
He thought a 20% fluctuation would trigger a margin call, feeling very "safe".
But at three in the morning, Ethereum plummeted 8% in five minutes; he didn’t even have the chance to add margin, watching helplessly as his account went to zero in an instant.
That wasn’t just a number; it was his money prepared for withdrawing to buy a phone.
Many people mistakenly believe that a full position = resistance to volatility = invincibility, forgetting that it is more like a double-edged sword —
it can give you a little more breathing room during fluctuations, but it can also cut off all escape routes when you go all in.
With the same full position and 10x leverage, why do some people survive while others are wiped out in one go?
The key is not the leverage ratio, but how much "life" you are betting.
For example, if you have 10,000U in your account:
· If you open a 50x position with 1,000U and your direction is wrong, you stop loss, and you still have 9,000U to come back.
· But if you open a 10x position with 9,000U, even with just a 10% fluctuation, you will be out directly.
What truly determines life or death is not whether you choose a full position or a partial position, but whether you have left yourself an escape route for the possibility of being wrong.
I also use a full position now, but I have set three iron rules for myself:
· Single position ≤ 20% of total assets
· Stop loss set within 3% of the entry capital
· Absolutely never bet heavily on direction in a fluctuating market just because "I feel it will rise/fall"
If you want to survive in the contract market, it’s not about praying for the market to go as you wish,
but about being fully aware of how much loss you can bear and never crossing that line.
The true meaning of a full position is not to gamble everything at once,
but to allow you to respond to uncertainty more flexibly within a controllable range.
