1000U at 10x versus 2000U at 5x: on the surface, these are two different ways to set up a trade, but at their core, they ask the same question: how many chances do you have left?

Let’s lay out the numbers first. Either way, your notional position can reach 10,000U, and a 1% market move would mean roughly 100U in profit or loss. In other words, what really determines how your gains or losses feel isn’t whether you put up 1,000U or 2,000U in margin—it’s the size of your total position. Leverage doesn’t change your potential profit; it changes how close you are to liquidation.

With a 10x long, a roughly 10% drop in the asset puts you on the edge of a cliff. With a 10x short, a roughly 10% rally is just as dangerous. At 5x, the buffer widens to around 20%. In real trading, fees, funding payments, and maintenance margin will gradually eat into that room, but the overall scale stays the same.

Now consider how many mistakes you can absorb. Say you have 10,000U. If you put up 1,000U at 10x each time, in theory you can be wrong about 10 times. If you put up 2,000U at 5x each time, you have about 5 chances. The profit ceiling may not differ much, but your number of chances to survive is cut in half. Which should you choose? The answer isn’t in the market—it’s in how well you can handle being wrong.

Many people treat analysis as the whole of trading, as if getting the direction right guarantees a win. But getting it right is only your entry ticket. What you do after entering—how you add, reduce, and exit—determines whether you stay at the table or get carried out. Position management boils down to two things: how you allocate your money and control risk; when and how much to add; where and how much to reduce.

There’s no one-size-fits-all formula, but there’s one thing you mustn’t do backward: only consider adding in the direction of the trend after unrealized profits have moved your entry cost out of danger, and add less with each step. Your initial position should do the heavy lifting; later additions are just supplementary. When you’re losing, gradually reduce your position—don’t keep adding as the price falls and mistake averaging down for courage. Only those who can manage both risk and returns have a chance of making it to the next round. Those who focus only on profit are often taken out by a single wick.

So don’t fixate on 10x versus 5x. Ask yourself first: if this trade gets liquidated, how many chances will I have left? If the answer is one, then no matter how accurate your analysis is, you’re gambling. I’ve written about how to match leverage with position size at @鑫鹰说财 .
