When you first enter the crypto world, the most intimidating thing is those technical terms. Opening a position, closing a position, holding a position—these three words probably confuse many newcomers. Let me talk to everyone about these concepts; they’re actually not that complicated.

Let's start with opening a position. Simply put, it means establishing a trading position in the market. If you believe a certain coin will go up, you buy it—that's called opening a long position. Conversely, if you think it will go down, you sell it—that's opening a short position. When opening a position, you need to prepare margin, which is the funds you use to cover potential losses.

What is closing a position? It means shutting down the position you’ve already opened. When you feel the price has reached your target, or if the market moves against you and you want to cut losses, you can close the position. If you are long, you sell; if you are short, you buy back. Basically, closing a position is ending the trade and realizing your profit or loss.

Holding a position means you are still maintaining your current position. If you bought but haven't sold yet, or if you shorted but haven't bought back, you are holding a position. The profit or loss of a position depends entirely on how the coin's price moves, which is why many people keep an eye on the market.

Regarding calculation, there are actually four key elements: the price at opening, the current price, the trading volume, and the profit or loss amount. For example, if you buy 1 coin at $100, and now the coin price is $120, your profit from the position is (120 - 100) × 1 = $20. If you are shorting, the logic is reversed.

The profit or loss when closing a long position = (current price - opening price) × quantity; for a short position, it’s (opening price - current price) × quantity. The calculation for holding profit or loss follows the same logic.

Honestly, the question of what closing a position means seems simple, but truly understanding when to close is the core of trading. Many people lose money because they don’t time their closings well. Some are too greedy, refusing to close even when the market weakens; others are too hasty, closing early before reaching their target.

My advice is to always decide based on your risk tolerance and market conditions. Don’t follow the crowd blindly, and don’t hold on stubbornly. The key to opening, closing, and holding positions is risk management. Enter when it’s right, exit when it’s right—that’s how you can survive longer in the crypto space.
