Hey, if you're new to crypto trading, there's one fundamental thing you need to understand: PNL. It's literally your profit or loss on each trade. End of story.

Here's how it works in practice. You buy BTC at $40,000, say 0.1 BTC, so you spend $4,000. A few hours later, the price rises to $42,000 and you decide to sell. You get back $4,200. The difference? $200 profit, minus platform fees. That’s your PNL: around $198 after commissions. It’s that simple.

The basic formula is just: selling price minus purchase price, multiplied by the quantity, minus fees. If the result is positive, you played it well. If it’s negative, well, you lost money on that trade. It’s basically the thermometer of your trading, honestly.

But wait, there’s an important nuance. There are two types of PNL you need to know if you really want to master your game. Unrealized PNL is when your position is still open; you don’t know yet if you’ll win or lose because you haven’t closed the trade. Realized PNL is when you’ve already sold and know the actual result. It’s the difference between dreaming of a profit and actually having it in your portfolio.

To visualize it better, just imagine you buy a coffee for $50 and sell it an hour later for $70. Boom, you make a $20 PNL. If you had sold it at $40, it would have been a $10 loss. In crypto markets, it’s exactly the same, except the numbers move faster and you’re trading thousands of dollars instead of coffees. That’s why understanding your trading PNL is crucial to avoid messing up.

One last thing: leverage can really amplify your PNL, in both directions. So be careful with that.
