I just realized that many people are still confused about what PNL means in trading. In fact, this is the most basic thing you need to understand before starting serious trading.

So, PNL stands for Profit and Loss, which simply shows how much money you profit or lose from each transaction. Basically, it's like a thermometer for your trading financial health. If PNL is positive, it means you're making a profit. If it's negative, it means you're at a loss.

The calculation is actually very simple. Just take the selling price minus the buying price, then multiply by the amount of assets you sold. Don't forget to subtract transaction fees too. The formula looks like this: PNL = (Selling Price – Buying Price) × Quantity of Assets – Fees. That's it.

For example, you buy 0.1 BTC at $40,000, so you spend $4,000. Then you sell at $42,000, meaning you receive $4,200. The difference is $200, but after deducting exchange fees, your PNL becomes +$198. That means you made a profit $198 from that transaction.

But it's very important to understand the difference between Unrealized PNL and Realized PNL. Unrealized PNL is the profit or loss that hasn't actually happened yet because your position is still open. Meanwhile, Realized PNL is the profit or loss that has definitely occurred after you close the position. This is a big difference because prices can change at any time before you sell.

There’s also the term Volatile PNL, which happens when your profit or loss changes drastically due to price fluctuations. This is common in volatile crypto markets. You can make big gains within hours, or suffer big losses too.

Let me give you an easier analogy. Imagine you buy coffee for 50,000 IDR, then an hour later, you sell it to a friend for 70,000 IDR. The difference is plus 20,000 IDR—that's your PNL. But if you sell it for 40,000 IDR, your PNL becomes minus 10,000 IDR. In crypto exchanges, the system is exactly the same, only the numbers change faster, and what’s at stake isn’t coffee but thousands or even millions of rupiah.

So, basically, understanding PNL is the first step to becoming a smarter trader. Don’t trade without knowing how much you’re actually making or losing. Keep monitoring your PNL, both realized and floating. This is the key to managing risk well and making more informed trading decisions.
