Although I am not enforcing you to do the same, many of the top traders I know, whether in stocks or forex, such as @Trader Dante, CryptoCred and some of the members on RealDayTrading Reddit, have always suggested it, regardless of whether you are a newbie or not. On top of that, the data or the history recorded on the platform won't be enough because it lacks the information that a customized trading journal has including some notes on why you enter a trade, notes during your trade management, and the likes.
It is not a waste of time, it's about having your due diligence to reflect on your trades.
