I just noticed that many beginners in crypto ask what exactly PNL is. So here’s my explanation without too much technical jargon.

Look, the meaning of PNL in finance is pretty simple: it’s the difference between what you paid for an asset and what you got when you sold it. End of story. PNL stands for Profit and Loss, and it’s literally your financial thermometer for each trade.

The formula is almost obvious: Sale price minus purchase price, multiplied by the amount you bought, minus exchange fees. That’s it. If the number is positive, you made a profit. If it’s negative, you lost.

Let me give you a real example: imagine you bought 0.1 BTC at $40,000 — you spent $4,000. An hour later, you sold it at $42,000 and received $4,200. Your gross profit is $200, but after subtracting the platform fee, you’re left with about $198. That’s your positive PNL.

Now, here’s where it gets interesting. There are two types of PNL you need to know: unrealized PNL, which is what you gain or lose while the position is still open, and realized PNL, which is what you’ve already closed and is in your pocket or out of it.

Many people confuse PNL with ROI, but they’re not the same. ROI is the percentage return on your initial investment, while PNL is simply the amount of money you gained or lost.

When trading with margin or leverage, PNL becomes much more volatile because you’re amplifying both your gains and your losses. That’s why it’s important to understand this concept well before playing with those instruments.

In summary: PNL is your final result. Understanding it well is the foundation of any serious trading strategy. Without knowing exactly how much you’re earning or losing on each move, you’re trading blind.
