What exactly do you mean when you say this: > IIRC they can legally front-run your orders. I doubt this is true, but there are definitions attached to front-running.

How far have you tried to tell, and do you buy/sell stocks? There's someone on the other side of your trade when you want to trade something. You're more likely than not choosing to interact with an HFT player at your price.

This comment, and its posters' subsequent comments, are so filled with anger, much misguided, that it's hard to really respond. Jane Street has some good people. Harvard has some good people. Both have some bad people. I don'

Hard to speak for HFT in general. Like in software, different firms have different levels of hygiene. About half of your bullet points were true of my previous employer, at my time of leaving.

I can see how you can come to this conclusion from this sentence, but it's a vague sentence with slightly-wrong premises, which leads you to this conclusion. If you're a programmer, I think you may appreciate this situation when

I'm going to have to jump in here and say, no, HFT can and does not front-run your trade. There are reasons why your execution on RH is not as good as professionals, but it's not because of front-running.

Agreed with the rest, you should just look at job descriptions. Different firms use different technologies, but a devops person will probably be building tooling for monitoring live trading, or GUIs for themselves and traders. These tend t

I have to disagree, I know that HFT != electronic trading. HFT is also not equivalent to arbing over latency.

You were replied to, but I'm going to ask some questions of this moralizing. > Many HFT jump out when things get volatile, when liquidity is actually required. This feels almost like a "no true Scotsman" situation. Why is

++ this. If they haven't tested this in actual trades and measured results, it's probably worthless. Even backtested strategies at actual firms observe decays (or don't work) when they get put live. And those are places where

(1) -- ok, sure (2). That is not what I said. To sell at P+dP, you need to buy up all the shares at P+dP as well. That's because of price-time priority, which almost all the major markets have (with some exceptions, most notably NYSE

This doesn't sound right. Some points: - A trader looking to buy futures is almost certainly not going to send their order to several exchanges. The main exchanges list distinct contracts (with, I believe, some cross-exchange listing

I'm in HFT (as per my handle). Exchanges like NYSE, NASDAQ, etc. sell stock data to firms but not before they get processed . The only way you get front run is if the broker that you submit through (ETrade, Schwab, etc.) notes your o

I think it's pretty clear that HFT has a big role in this. If you look at the order books of US equities, most of the most aggressive orders on the book are ones that look like they come from high frequency strategies. Furthermore, i

In response to situation (2), I want to first tighten the language - as it stands, I'm not sure if it's even possible. By computers, I think you mean exchanges (for example, Nasdaq, BATS, etc.) So somebody wants to trade 50 shar

The industry doesn't really make that much money. Estimates for this past year were in the $1-2 billion range. That's not big for the finance sector, or any industry. That being said, it doesn't take that many people to ru

I can't reply to that thread (maybe it's because it was too long ago), but you draw a difference between someone moving a large block (as described in yummyfajitas' post), and someone trading a small size (50 shares). So let

Where does this assertion come from? If you take a look at the market book, then you might see that yes, most market-makers (liquidity) in the equity markets are high-frequency orders.

Maybe he's not a sinister person, but he tells narratives in which his side is unambiguously good. What happened in this book was lazy research and poor journalism. There have been plenty of factual critiques, which should set off
