      I stopped believing the stock market meant anything ever since computerized high-frequency trading became a thing.

        HFT is about faster price discovery and often is just arbitrage between exchanges.

        If the New York Stock Exchange price of AAPL is $1 more than the Chicago Exchange, then a HFT detects that and buys the Chicago Exchange’s AAPL + sells NYSE AAPL, bringing price discovery to the masses.

        That’s why HFT is, in practice, allowed. Because the vast, vast, vast majority of HFT is important arbitrage between our collection of exchanges in the USA.


        These “dumb” price differences need to be fixed, and it makes sense for the people who discover these differences to profit from them. It also provably makes the markets smoother and better for everyone involved. (New York can know that the price changes over in Chicago will affect them within milliseconds, keeping all the exchanges across the country nearly in sync).

          That may be how it is now. AI will be employed to make stock trades independently very soon if it hasn’t started yet.

            Have you even used ChatGPT? Its slow as fuck.

            HFT is trading within milliseconds. Not trading within dozens-of-seconds.

              That is because you are relying on connecting to their servers rather than having your own extremely powerful ones.

              Also, this would be a completely different sort of AI than a glorified chatbot.

                Uh huh. So you’re just spitballing I take it.

                Name the algorithm. What’s the AI algorithm that’s about to take over the high frequency trading world? A .pdf or citation to a journal would also be nice, something that explains why this new hypothetical algorithm you’re talking about is better than the HFT / Arbitrage that I talked about earlier.

                  Yes, of course I’m spitballing. Because I said it likely hasn’t happened yet. I’m not sure why you would expect me to name the algorithm for something that hasn’t happened yet.

                  Are you under the impression that it’s not possible?

        The stock market is based upon human behavior and however flawed and irrational it is. Even HFT works to exploit human behavior so I bundle it into the same category.

      Oh that much is very true and this and reddit pretty much show it. Though I can’t say I’m not trying to at least profit off of reddit’s insanity. Play the absolutely shitty game.

    I’m still left wondering how it isn’t election interference if a foreigner invests in DJT.

    Anything is worth exactly what you can sell it for. Currently, who the hell would pay a nickel for that POS platform? Of course, I’m sure that Elon has a doppelgänger somewhere.

    I’ve never used it, don’t know anybody who uses it, and can’t even tell you the URL.

    Then again I currently only use Lemmy.
