I've been seeing novice traders check their charts every 5 minutes but have no idea what PnL in trading is. Bro, that's a problem.

Look, PnL stands for Profit and Loss, basically your gain or loss on a trade. Sounds simple, but it's the most important thing you need to understand if you want to stop losing money. When you close a position, the PnL shows you exactly how much you gained or how much you burned. Without that, you're trading blind.

What many don't understand is that PnL isn't just a number. It's your mirror. It tells you whether your strategy works or if you're throwing money away. I know people who trade for months without really reviewing their accumulated PnL. Spoiler: it ends badly.

Now, here’s where it gets interesting. Understanding what PnL is in trading is the first step, but the real skill is interpreting those numbers. It’s not about winning every trade. Believe me, the best traders I know lose trades all the time. The difference is that their profits outweigh their losses in the long run.

That’s risk management. That’s what separates those who struggle their whole lives from those who truly build wealth in crypto. An amateur sees a negative PnL and panics. A professional adjusts their strategy, reviews what went wrong, and keeps going.

My advice: review your PnL every week. Not obsessively, but with discipline. Look for patterns. Do you lose more at certain times? With certain pairs? That’s valuable data. Controlling your PnL is controlling your future in trading.
