In a way your family is doing the same thing I'm doing, they deposited in a fund and you trade for them, and I basically deposited in a fund that the trader trades for me (it's all automated).

But yeah, it's not sustainable long term. I'm going to increase my portfolio in this copy trading account to $10k, after it I'll put some on the side to trade in the market and start learning a bit, probably going to use your indicator too :)
