Many beginners enter the market with contracts, and their first reaction is to turn on full position mode. The reasoning sounds smooth: it can withstand fluctuations and is less likely to be wiped out by orders. But this is actually a big misconception. Full position is never a "casual add-on" shield; using it incorrectly can lead to faster ruin.

The real purpose of full position is simply to leave more room for maneuver in your account, not to mean you can pile all your funds into a single trade.

I've seen too many people make this mistake. An account with only a few thousand yuan dares to use ninety percent of its funds for a short-term trade, comforting itself that this is more stable. But what happens? Slight market reversals can instantly wipe out the margin, trigger forced liquidation, and the account can go to zero immediately—without even a chance for manual intervention.

Why do some people survive with the same leverage while others are wiped out? The answer is painfully simple: it’s not about how accurate your market prediction is, but whether you’ve calculated your position size in advance.

Some people notice the wrong direction early, reduce their position to stop losses, and keep losses within a tolerable range. Others, holding onto the hope of "it will come back if I wait," stubbornly endure, only to have their funds completely swallowed. The difference isn’t huge, but the outcomes are worlds apart.

Here’s a real-world example. Suppose your account has only 1,000 yuan, and you use only 100 yuan to open a high-leverage position. Even if your judgment is completely wrong, you still have 900 yuan of buffer, and your account can continue to operate without issue. But if you directly commit 800 yuan or more— even if the leverage isn’t extremely high—a normal market fluctuation can easily cause your entire account to spiral out of control.

Leverage is essentially an amplifier; it magnifies your gains and, proportionally, your losses. What truly determines life or death is never how high the leverage is, but how much principal you are risking on that single trade.

So stop obsessing over the false question of "how many times leverage is safe." First, ask yourself three practical questions: what percentage of my total account funds does this trade occupy, where exactly is my stop-loss level, and if the market moves completely against me, can I accept this loss?

Answering these three questions clearly is more effective than any trading technique. Full position mode itself isn’t a safety net; the real safety net is strict position management and trading discipline. Staying alive is always more important than anything else.
