I've noticed that many beginners in crypto get confused with PNL and don't understand how to properly calculate their profits and losses. I decided to take a closer look at this issue because it's really important for any trader.

So, PNL essentially indicates how much money you've earned or lost on your trades. It sounds simple, but there are some nuances. When I first started trading, I didn't pay attention to this metric, and then I realized it was a serious gap in my approach.

In general, PNL is not just a number on the exchange interface. It's a real tool for assessing whether your strategy is working or not. There are two types: realized and unrealized. Realized is when you've closed a position and locked in the result. Unrealized is often called paper profit because it's the potential income from open positions that haven't been closed yet. The second fluctuates with the market, while the first is your actual result.

When calculating PNL, you can use different methods. FIFO — the most common, where you sell the oldest purchased assets first. LIFO works the opposite way and can be useful during volatility. There's also the weighted average cost method — if you've made many purchases at different prices, this method provides a more objective picture. And percentage-based calculation, which shows your return relative to your initial investment.

Why is this so important? First, by analyzing your PNL, you see which strategies actually make money and which don't. Second, it helps with risk management. If you track losses, you can set stop-losses or close positions in time to avoid losing everything. Third, it protects you from emotional decisions. Instead of acting under the influence of fear or greed, you look at the numbers and make informed decisions.

Tracking PNL over time helps identify patterns. Maybe you trade better on certain pairs or at specific times of the day. Maybe your best trades are those where you hold a position longer. Or, conversely, short-term movements suit you more. Only by monitoring results will you understand this.

Most exchanges have built-in PNL tracking right into the trading interface, so you see results in real time. There are also third-party apps that integrate with multiple exchanges and give a complete picture of your portfolio. If you want maximum control, you can calculate everything manually using spreadsheets, but that's for the very meticulous.

In general, PNL is not just boring accounting. It's your personal indicator of success in crypto. Without understanding this metric, you're just guessing whether your trading is profitable or not. And if you want to trade seriously and earn steadily, analyzing PNL is an essential foundation. Start tracking your results, and you'll quickly see where you're making mistakes and what needs to change in your approach. On Gate, you can track all this well once you get familiar with the interface.
