    Paul Graham Retweeted Conrad Barski

    This is a genuinely good startup idea. Not so much in itself as for the beachhead it could give you. But if you work on it you probably owe it to Conrad to write it in some dialect of Lisp...https://twitter.com/lisperati/status/1175061642020892675 …

    Someone do a startup that simply takes past stock trading docs from your broker, cleans em up & generates rigorous/bayesian stats as to whether your trades outperform the markets (not so easy) Would be useful service for people who truly care if they're just "fooling themselves"

        I built integrations to @TwitterAPI and @Stocktwits . Applied ml/text analytics to surface buy n sell signals. It's a pet project of mine.

        This could be built quickly using Plaid’s investments product.

        And to make the analysis actionable automatically into transactions, connecting with @AlpacaHQ https://alpaca.markets  trading API is the easiest.

        I’ll bite. What makes it good? The market is small and there’s no moat around the castle. This looks like feature that others could quickly add, not a product. P.S. We wrote a blockchain in Lisp at Emotiq.

        It would appeal to fanatics, who are the ideal early adopters.

        In my experience, folks who claim to outperform the markets have little interest in whether the Sharpe and Sortino ratios of their performance validate that claim

        I agree your statements holds multiple truths (1) many of those people are probably fooling themselves at some level (2) Sharpe/sortino are perhaps the wrong metrics (3) not enough education tells them that they have reason to care.
