It could be hard to track if you are using different coins in trading and especially when you are doing a day trading. But I don't think it was very important to have it track since I believe that you are a full-time trader and you are watching it all over the day, unless if you have another job.
This is when crypto trading tracking platforms that use exchange API keys come in handy. Everything is automatic. I use 3commas and Bituniverse but i have never had to pay a fee to tracking my trades, Profit and losses. The fee only comes in when i want to use their bots for automated trades.
