Recently, someone asked me what PNL really means in the stock markets, and I realized that many new traders are not clear on it. So here is my explanation without too much technical jargon.

Basically, PNL is your financial thermometer in each trade. It tells you exactly how much you gained or lost. The thing is simple: it’s the difference between what you paid for an asset and what you sold it for. That’s, in essence, what PNL is in finance.

Look, the formula is very straightforward: Sale price minus Purchase price, multiplied by the amount you bought, and then subtract the commissions charged by the exchange. If the number you get is positive, congratulations, you made a profit. If it’s negative, well, that’s part of the game.

I’ll give you a real example that probably sounds familiar. Imagine you bought 0.1 BTC when it was at $40,000, so you invested $4,000. Then the price went up and you sold it at $42,000. You received $4,200. In theory, you made $200, but the exchange takes its commission, so your actual PNL was about $198. That’s what it means to see gains in crypto finance.

Now, there’s something important you should know: there is unrealized PNL, which is when you still have the open position and the value goes up and down constantly. And then there’s realized PNL, which is the one you’ve already closed, the one that’s already yours.

Volatility plays a key role here. When the price moves a lot, your PNL can change drastically in minutes. That’s why some traders talk about volatile PNL, especially in markets like these where everything moves quickly.

To understand it better, it’s like buying a coffee for 50 and selling it an hour later for 70. Your profit is 20. That’s your PNL. If you had sold it for 40, your PNL would be negative, a loss. In the stock market, it’s exactly the same, only instead of coffees, we’re talking about thousands of dollars, and prices change every second.

What you must remember is that understanding what PNL is is fundamental for anyone who wants to trade seriously. It’s not just a number; it’s the real reflection of whether your strategy is working or not.
