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?
If you trade on a decent exchange like Binance, Bittrex, Poloniex, or actually I believe all exchanges should have this featured called "trade history." From there alone you should be able to see your total buys, total sells and even trading fess all of which are enough to compute anything you would want to track.
However, if you really want to do it outside, I'd suggest taking at the "Delta" portfolio app.
