First look is still not front running. Unless you are able to get your order in before other orders, it’s not front running. Get it? Being the first to look at new orders is nice, but the orders are in the queue so there is no way to get in front of them. Here is a link to help you: https://www.investopedia.com/terms/f/frontrunning.asp It’s very well-defined in the industry and when you complain about something compl…

Again, this is exactly the behavior I mentioned in the above post. When the general public raises the important question of how much extractive behavior there is in HFT and asks whether the benefits outweigh the value lost by disadvantaged parties, they get brushed off and told that they’re ignorant. Your response focuses on one specific technical allegation while casually admitting that yeah, maybe there’s another t…

i wonder this; if there is a stop loss already on the books at x price and a HFT enters a market order at that price when a stock is falling, which order will get filled first? i feel like answering this question would sort of answer the argument you guys are making?

as for useful work... we should really just be honest with ourselves/each other [and machine learning/ai might help us to do this] about what is actual useful work. it begs to challenge freedom, but ultimately i think we're headed for an efficiency level that will make the most efficacious worker look lazy af...

Kilowatts? wtf So much for that hobby. Where were those links supposed to go anyhow?

Maybe there's a hobby in receiving their trading data and having software react to it — following milliseconds behind their trade.

Milliseconds are an eternity.

I see where you are going here, but it seems to be many orders off magnitude off in time relative to HFT.

its highly counterintuitive to see the modern system in the same terms as the capital markets of last millennium. and I'm convinced the system isn't perfect, I'm sure there are things that should be changed. I'm merely suggesting that the market sped up as people learned to do market stuff faster, and that market stuff is ultimately a process of allocating capital resources.

I haven’t seen any claims that HFT is allocating capital in better directions. They’re mostly reacting to the same signal and trying to trade the same asset at the same price, right? That’s the only case where the latency matters, because the market uses order time to break ties.

One does not need a lot of bandwidth to trade successfully. In fact, a limited number of signals agreed upon ahead of time is enough. E.g. signal “A” could mean “buy 10 contracts”, signal “B” - “sell 100 contracts”, etc. And you can of course wrap 256 such signals into one byte. So transmitting a single byte at an opportune time let’s you control your trading on the other continent in a quite precise fashion. If you…

All you really need to do is to beat the trade you just saw enter the system so you can buy the trade out from under them and mark it up while their bits are still stuck in glass. You know, "provide liquidity".

That’s not at all how it works.

How much time does encryption take? I'd wager the fastest links are close to plaintext.

I'm sure I'm not the only one who would like to see the whole HFT industry be deleted. What a waste of human intellect.

For sure. There needs to be a cost charged by the exchanges (federally required) which decreases with time.

Nearly every symbol traded on exchanges trades with “price/time” priority meaning that the order that rests the longest at a price fills first. This provides a very big incentive to keep orders on exchanges for a long time.

The only time there is a speed race in these symbols to _place_ an order is when they are filling in a missing level. That is providing quotes at better prices. Why would you want to make that more expensive?

Think I found them.

Using the update from the bottom of the page:

> … and M-Wave is authorized the 14-14.99 MHz at 16 kW.

I found this petition from M-Wave Networks, LLC for permission to build 4 towers in Kane County, Illinois: https://www.countyofkane.org/FDER/Zoning%20Petitions%20Docum...

The location in the petition is approx. 41.82907908782928, -88.4940281199101, which is about 16 miles (27 km) from the center coordinate of the TDOA map (41.60, -88.60). Not bad given the caveat of "the above location is likely accurate to only a few 10s of km at best."

The e-mail address in the petition has the domain tower-research.com, which is a high-frequency trading firm.

The only thing I'm confused about is that the zoning petition was discussed at the meeting on Dec 8th 2020. If it was approved, it seems remarkably fast to build a tower given that the article was from Dec 15th.
