Tower Research has hired Marvin Arteaga from Millennium as head of mid-frequency trading strategies
Arteaga spent 12 years at Millennium, mostly as head of algo execution technologies. Before that he spent seven years in algo development at Bank of America.
He is based in New York. Millennium hired Tower CTO Alexandre Fournier earlier this year to work on low-latency tech. Tower's co-head of IG credit trading, Wesley Chen, joined Millennium as a PM in June.
MFT positions run from minutes to days. Jane Street and Hudson River Trading are building out the same capability.

What good does regulation do when there is no exchange enforcement?
I asked @CMEGroup CEO Terry Duffy if, in his view, there are literally any laws anymore when it comes to financial regulation.

Some day people will realize that financial markets can be manipulated on a massive scale. A firm needs to be able to identify the tails, understand how they interact, and have the power to wag them all.
Jane Street is that firm.
Great test to find wisdom-less nerds who would never question if the trading strategy that they were working on was market manipulation.
Jane Street pays new graduates $400K+ a year, and the hardest question in the interview isn't a math problem. It's "why?"
They might ask you to make a market on two dice, push back on every number you give, and then change the setup halfway through to see if you can adjust without starting over.
A lot of people can find the answer. Far fewer can stay exact while the problem keeps moving under them.
Below are 31 questions in that style, written to match how these interviews work rather than taken from any firm. Give yourself 45 minutes and no calculator.
Answers with the reasoning are in the comments, and if you got one right but can't explain why, count it as wrong.

Anthropic has to figure out Quantization. So frustrating when models turn into retards before a new release.

A Jane Streets broker could only handle ONE firm executing the “trading strategy” they were doing. When another firm executed the same strategy, Jane Street was shut down.
Wonder if massive risk and a massive loss was foreseeable🤪

Not a single fact-based insight or statement. Just emotional and meaningless dribble. Useless scoundrels like Ro have done more damage to our Country than anyone.
Ro Khanna: Elon Musk is an arrogant, dangerous demagogue who doesn't care about society. He also claimed that Musk got radicalized, possibly because of his trans child and his desire to belong.
Ro Khanman was on NPR discussing his likely run for President. Hopefully he runs so he can see how much people can't stand him. He spent the entire past year on grifts and stunts, all for his upcoming campaign. He is the ultimate fraud.
Khanman said that unlike Musk, Rockefeller cared about society, as evidenced by his name being on libraries. 😂

Candace Owens explained…
We are witnessing the end of Candace Owens.
Not only is she factually incorrect and exposing herself as a liar and a lunatic, look at her nervous and manic behavior.
Her body language is defensive, hostile, and lacks confidence. She is nervous and constantly looking at PBD for approval and for him to save her, only for her to be exposed as a fraud.
It’s time for Candace and her cultists to give it up. It’s over. All of you were duped by a psychotic grifting demon, and it’s time for this circus to end.
Yeah can’t let people see the manipulation.

For most younger people in America, technology encourages them to measure themselves against manufactured realities, breeding jealousy and distorting their perception of where they actually stand in the world.
Great environment for the false hope of Socialism to thrive.
America is extremely rich.
In terms of household final consumption per capita, every state is richer than every foreign country.
Sub in anyone, and they'd be in 51st place. In fact, plenty would even be behind American territories like Puerto Rico.

cc @DRWTrading how much do you guys currently pay for faster access in your private deal?
The Trump family’s media group is asking large trading firms to pay for ultrafast access to the US president’s often market-moving posts on Truth Social. ft.trib.al/LarKSxb

This is truly remarkable & equally dumbfounding given the current dynamic around these events.
Is it possible they were caught giving priority access and this is their convoluted response to level the playing field?
