How do you accurately track P&L and other statistics outside exchanges?

Is anyone else struggling with exchange P&L tracking? I’ve been getting more and more frustrated with this lately. I’ll open a trade, close it in profit, and then the exchange shows completely different numbers than what I actually made. It just doesn’t line up at all.

What really annoys me is the daily P&L. For example, I open a trade late at night (around 11pm), it dips a bit, I go to sleep, and then it hits TP at like 2–3am. In my head, that’s clearly a winning trade. But the exchange logs it as a loss for the previous day because of how they split P&L. Makes no sense when you’re trying to track performance.

The UI doesn’t help either — everything feels messy and hard to interpret. I genuinely don’t feel like I have a clear picture of how I’m actually doing.

Is this just me or are others dealing with the same thing? Have you found any tool or method that actually gives you clean, accurate tracking?
