A market is a market, is it not?

no, securities aren't the same as retail products

Most things are different from each other. Why does that difference matter in this case? It looks a lot like traders trading in a market. That isn't manipulation.

Isn't the problem that this allows for all kinds of forms of insider trading? > Insider trading—the practice of buying or selling a company's securities based on material, nonpublic information—has long been a contentious issue in financial markets. https://www.investopedia.com/terms/i/insidertrading.asp There's also a question of whether they are good for the health of the overall market: https://www.cbsnews.com/new…

It stands to reason that if the buyer/seller are seeking private rooms there is something unfavorable for them about "lit" trading. That alone should raise red flags.

That raises red flags that the standard market regulations are bad - they are signalling that they believe an exchange with different rules is better for both traders. That would be bad for all the traders stuck on the exchange with inferior rules, but the solution is to reform the standard exchange.

Probably trying to get away from HFT if I were going to guess blindly.

>I suspect that this is the absolute core of "dark pool" strategy. Any trade that happens behind closed doors that "doesn't impact prices" means that an index fund is buying or selling at a price other than the "real" price meaning that dark pools are functionally a wealth transfer from grandma to an institutional trader.

Is there evidence for this, or this all baseless speculation?

It is not clear to me what nefarious things people believe are going on there that we should be worried about. All the article says is that people are doing things we don't know about, but implies that somehow we should feel not-okay about this. I don't know what's going on in my neighbor's house either, and it could certainly be bad stuff, but that's doesn't mean that it is bad or that I should start spying on them.

For me stock market should be about transparency of trades.

Of course small trades aren't relevant, but big ones should be visible.

Ban high frequency trading, ban instant transactions (put them on hold for some time before buying/selling (hours minmum, longer for larger quantities), make the held transactions public, and tax the profits on a time-owned scale. This would turn "investments" into investments again... you really believe that company XY will do something good? Buy stocks and keep them for few years until they grow. Politican John Bob…

HFTs/market makers are competing for pennies on the dollar. They do not hold risk (long term), they exist to readily provide liquidity to your buy/sell orders. HFTs can be quite profitable, but that doesn't make them inherently evil.

Can you elaborate why those bans will improve the market and what the issues are with HFTs in your eyes?

It's actually the other way around. As a big fund looking to trade a large number of shares in the public market, you'll quickly realize that the market tends to move away from you, and statistically, you're more likely to get a bad deal than a good one. Even if you try to be smart about execution by splitting your orders into chunks, randomizing order sizes, and similar tactics, there is still a huge information asymmetry between you and more sophisticated players. In many cases, they can classify your orders based on different characteristics of your order flow (such as latency profile), distinguishing them from so-called toxic flow from other HFT firms.

The purpose of these private rooms is to separate your orders from those players so that you trade against other uninformed parties, making your chances of getting a good or bad deal closer to 50/50.

I've been wading through terabytes of financial data over the past month. (I'm an ML/AI software engineer trying to create a trading bot that makes me more consistent income during times of uncertainty that are outside my control.) This is some of the data I'm looking at. NVDA price on a particular day vs. average position of trades in bid ask spread aggregated over 10 seconds, on all the exchanges it is being traded…

There might be other ways to know about the data in advance? Some kind of flaw somewhere that lets us sniff the “dark rooms”?

There might be other ways to know about the data in advance?

Yeah, just have lunch with a few of the insiders. That's the issue and will always be the issue.

Depends on the volume

Fine, is OpenAI doing "manipulation" when they buy 10k H100s from nvidia directly, rather than on the open market?

If it causes "no liquidity" in the open market because nvidia (tsmc) can only produce so many GPUs / month and that causes nvidia's other cards to have a street price of 2x MSRP due to lack of availability? I would say yes.. It's just that "H100" or "RTX 5090" is not a registered stock with the SEC, so there aren't specific laws / penalties for manipulating the GPU market.

Same as "10 per store" limits when PS5s or whatever are in short supply, but then the CEO calls up the warehouse to get one for every student in their kid's class.
