Been trading for a while now and I see the same pattern over and over — people are absolutely obsessed with checking their PnL every single day. Like, refresh the app, check the number, refresh again. It's kind of wild to watch honestly.

Let me break down what is PnL first for anyone just getting into this. Profit and Loss, right? Green number means you're making money, red number means you're bleeding. Seems straightforward enough. But here's the thing nobody talks about — that number is probably the worst thing you can be staring at constantly.

Why? Because the moment you start watching your PnL daily, emotions take over. You see a loss and panic hits. You see a gain and suddenly greed kicks in. Before you know it, you're making trades based on how you're feeling that day, not based on your actual strategy. I've seen solid traders blow up this way.

The other problem is tunnel vision. You stop looking at charts, stop reading market news, stop thinking about what's actually happening in the market. Instead you're just glued to that one number on your screen. It's like driving a car while only staring at the speedometer. Completely defeats the purpose.

Here's what actually matters — what is PnL really supposed to be? It's the end result of consistent execution over time, not a daily scoreboard. Your strategy is what counts. The PnL just follows if you stick to the plan.

So what should you actually do? Check your PnL maybe once a week, or honestly even once a month if you're serious about long-term gains. Instead spend your daily energy on actual analysis, learning new things, tweaking your approach. That's where the real work happens.

The traders who actually make it aren't the ones crushing it every single day. They're the ones who play the long game systematically. That's the mindset that builds real wealth in this space.
