I just saw that many in the community still don't really understand what PnL means in trading, so let me share my perspective on this.

PnL is basically your Profit and Loss, the number that tells you whether you made or lost money on your trades. It seems simple, but here’s the important part: most novice traders only look at whether they won or lost on a single trade, without seeing the full picture.

What really separates those who know what PnL in trading means from those who don’t is that professionals understand it’s not about winning all the time. Impossible. What matters is that your accumulated gains surpass your losses in the long run. That’s it.

I spend quite a bit of time reviewing my monthly and yearly PnL, not just per trade. Why? Because it gives you a real snapshot of how your performance is going. If you’re not checking this regularly, you’re basically trading blind. No data, no feedback, no way to improve.

Here comes the key point: controlling your PnL forces you to think about risk management. And risk management is literally what differentiates a professional trader from someone who just bets. You need to know how much you’re willing to lose on each trade, what your win-loss ratio is, and how to adjust your strategy based on your actual numbers.

If you still don’t understand what PnL in trading means or how to interpret it, I recommend you start documenting every trade. You’ll quickly see where your mistakes are and where your strategy works. That’s what makes the difference.
