Built a little game with Muse called Hindsight Capital. Eight anonymized real historical companies; you read the financials as they were at the time, decide to invest or pass, then live through the actual crisis that came next. You then see how you did.
Just built a simple but pretty useful dashboard with Muse. It goes through my trade confirmation emails and then benchmarks all of my trades against SPY performance since the trade. Buys earn positive alpha when the stock beats SPY and sells earn positive alpha when SPY beats the stock. Then it plots the aggregate alpha weighted by notional value over a time-series chart. I can also see alpha by every single trade. I actually used to maintain such a trade execution journal with a spreadsheet, but gave up due to sheer laziness as I had to manually input my trades. Well, not anymore😀
