That's cool, but what I'd really like to see would be some form of tool to define different strategies and visualize how they would've worked.

I mean, probably professional traders have tons of these to do back-testing, but it would be nice to have something simple that people could use to check basic strategies.

Just as an example, when I was still into BTC my "strategy" was to buy $100 very month, and in the end of the year I would sell just enough to get my money back and only if the average price went up in the year. It worked well for the bull years, and losses (if I was forced to realize them) were capped at $1200/year.

I think a tool like that should be good not just for crypto, but also to help those understand that sensible investing is not about timing the market and picking the right lottery tickets.
