I think I understand your view that low latency trading is fair competition. I see that from the perspective of traders, it's unfair skimming that's literally impossible to compete with. (Compare in more corrupt days, you could li

That's the term the SEC uses to explain why a fair market is important. If ordinary investors and traders believe that low latency traders have systematic advantages over them, they will lose confidence in the market and choose not to

In context, I mean that the fastest trader takes all of the profit associated with the price correction in response to new information. Your example isn't relevant since you placed your order without access to the new information. In f

Thanks for the thoughtful response. I'm still reading through the efficiency analyses. I note that none of your sources refute the fairness argument. Source [3] concedes it, concluding that "HFTs impose adverse selection costs on

The problem with HFT is that it's unfair and discourages investor participation. A batch auction system would level the playing field. Obviously, HFT is currently legal and profitable; I'm talking about reforming the market.

I don't want to argue semantics. I would like a straight answer on why you think that "fastest trader takes all" is a level playing field, or conversely, why implementing a batch auction format would be nonsensical. I'm

True, it's easier to prosecute insider trading as a breach of fiduciary duty to the company. But why were insider trading laws passed, and why is insider trading prosecuted? The SEC answers that "moral imperatives have driven the

The more expansive view of front running was most famously argued in Flash Boys , where "Lewis concludes that HFT is used as a method to front run orders placed by investors".[1] Under this definition, yes, why should traders nee

> HFTs and investors [don't compete] I started with an example where investors lose money due to adverse selection from HFTs, and I don't think that you've really addressed that argument.

I said compare insider trading. I'm aware that it doesn't involve insider information; the point is that some information advantages can be unfair. We want the market to reward real research, and not front-running.

I just found the SEC's official justification and amended my original comment above. I don't think you're going to win an argument against the SEC.

You're right, it was a poor example and I have deleted it. Perhaps we can agree that fairness would be an adequate justification for making insider trading illegal, and by analogy, that it would be an adequate justification for switchi

How are batch auctions more complex? You still use the same rules for resolving priority. How can the rules be gamed? Investors do not have any unfair advantages over technical traders. They take different approaches for price discovery, bu

I can rephrase without that assumption. The argument is that high speed traders are able to trade before others can receive or react to information. The time advantage therefore translates to an unfair information advantage. Compare insider

You claim that batch auctions are the same without addressing the arguments in the article, namely that (1) HFT is unfair to smaller traders, and (2) HFT is an arms race where the costs (materials, labor, and brainpower) exceed the benefits
