> Am I missing something here? Yes. By paying relatively small amounts to high frequency market makers in return for enhanced liquidity and price discovery, you won't be overpaying by 1% (or more). I also challenge the idea that i

That's not the point. The point is that the industry is vanishingly small compared to Wall Street proper, yet it has an outsize target on its head due to FUD and emotional appeals like the ones presented in the article. Furthermore, in

That article has two reasons, though it spreads "amplification" out among several factors. In fairness, I do agree with the problem of flash crashes, whether they are caused by algorithms moving too quickly or too similarly. I&#x2

Yes, and this is happening. The low hanging fruit in HFT is effectively gone, and you can no longer compete on just speed. The industry has been shrinking since the early 2010s.

Okay, fair enough. But do you believe these happen often enough, or will increase in the future, to outweigh the improvements to liquidity provided by HFT?

High frequency trading is not front running. It's becoming truly kafkaesque how often this claim comes up on Hacker News.

Your comment, while snarky, isn't a refutable statement. As it stands you seem to be endorsing some position, which I'm inferring is in favor of Sanders and maybe in opposition to HFT. I can't really tell what you're get

I didn't read that out of The Tangled Web. It did cover attacks, but it was also a solid guide on shoring up defenses for developers. To circle back to your question - nginx is fairly robust out of the box, but The Tangled Web will

I'll echo what the sibling comment said about CTFs. Those are a great way of drilling the theory in the same way you need to drill problems to really cement mathematical maturity. Practically speaking, read through each chapter and the

I'll clarify - I consider Security Engineering and TAOSSA to be landscape volumes - they cover a great deal of depth. Security Engineering is more on the defensive/development side while TAOSSA is on the offensive/a
