Looking for a Paper trading platform - Help!

I am trying to help my elderly father with his crypto. He has a little dementia and after recently being hacked and having over $2000 of BTC stolen, we have moved his coins to a cold wallet.

However he really wants to be able to look at them on a more than daily basis. I have looked at CryptoHopper to see if I can load his coins into that platform as a paper trading situation so he could look at the charts and see how the coins are trading. This is what he wants to do.

But I can not figure out how to load the coins in the paper side and don't know how to proceed. Is there an easier platform that I can load a variety of coins that will provide the charts and allow me to set up this 'test' portfolio? I checked Cryptohopper's FAQ and have no clue how to proceed, it seems to be focused solely on creating bots to trade without input and track that progress.

Any help?
