I have just started trading and was looking for some platform to keep track of my trades to see if I made profits or losses in the long run.
There are some portfolio managers, but they just track the different crypto coins and their current prices.
Is there any such tool or just google sheets that you are aware of that might be of help to me?
What exchanges are you using? Most exchanges have a built in system for this. If you go under your account information, you should be able to find a list of all of the orders you have ever placed in there somewhere. I've been able to go back and see orders from a few years ago on a few different exchanges. This is really all I ever use. You'll be able to see what price you bought the coin at and what price you sold it at.
