I've been involved in trading for a while, and one thing I see many beginners don't understand is PnL. So I'm going to try to explain what PnL is in finance in a practical way.

Basically, PnL ( which in Spanish means Profit and Loss ) is your actual result in each trade. Did you win? Did you lose? That’s your PnL. It sounds simple, but here’s the important part: most people don’t track this correctly.

At first, I made the mistake of only looking at whether the position was in the green or red at the moment. But that’s not enough. What really matters is understanding your performance over time. Your accumulated PnL tells you whether you’re actually making money or just getting lucky.

Many novice traders think the goal is to win on every trade. Mistake. The reality is that even professionals lose trades. The difference is that they manage their losses well. When they understand what PnL is in finance and monitor it constantly, they can adjust their strategy before everything falls apart.

The key is that your total gains exceed your total losses in the long run. Point. It’s not about win percentage; it’s pure math. A trader with a 40% win rate can make more money than one with 70% if they manage risk properly.

That’s why on Gate or any exchange where you trade, you should review your PnL regularly. It’s not just a pretty number to show off; it’s your health thermometer as a trader. If you see your accumulated PnL remaining negative after months, it’s time to rethink everything. If it’s steadily increasing, then yes, you’re on the right track.

The discipline of monitoring your PnL is what separates those who last in this from those who disappear after losing their savings. Without this control, you’re basically playing blind.
