When you first entered the crypto world, terms like opening and closing positions confused you, and only later did you realize what they really mean. Today, I want to talk about these common terms, especially the meaning of closing a position, because many beginners are still a bit unclear about this.

Let's start with the basics. Opening a position means establishing a new trade in the market; simply put, it means you are entering the market. If you think a coin will go up, you buy to open a long position; if you think it will go down, you sell to open a short position. When opening a position, you need to put up margin to cover potential losses.

Next, let's discuss what closing a position means. Closing a position means you are closing out an existing trade, which is essentially deciding to exit. If you previously opened a long position, closing it means selling; if you opened a short, closing it means buying back. The purpose of closing is either to realize your profit target or to cut your losses. It’s important to emphasize that closing a position simply means ending a trade and locking in your gains or losses.

Holding a position means you are currently maintaining a trade. After buying or selling a coin, you are in a holding state. The profit or loss of the position will fluctuate with the coin’s price, which is why many people keep a close eye on the market.

How are these calculated? It’s actually not complicated. The cost of opening a position is the transaction price multiplied by the quantity. The profit or loss when closing depends on whether it’s a long or short position. For longs, the profit/loss equals (current price minus opening price) times the quantity; for shorts, it’s the opposite, (opening price minus current price) times the quantity. The calculation for unrealized profit or loss of a position is the same as for closing, just that you haven’t exited yet.

In simple terms, closing a position means your trade is finished. In derivatives trading, these concepts appear repeatedly, and mastering them helps you better manage risk. My advice is to decide when to close based on market conditions and your risk tolerance, rather than blindly chasing gains or cutting losses. Also, remember to control your risk and avoid letting a single loss wipe you out.

If you’re still exploring, you can look at real-time market data on exchanges, practice while observing, and gradually understand the meaning of closing a position and the entire trading process.
