Why do the estimated births/deaths per second counters have so much flicker? Surely you don't actually believe that the expected number of births/deaths per second fluctuates at 1dp precision multiple times per second?
> The continuously updating global population counter is based on current aggregate birth and death rates (approximating values such as those from the U.S. Census Bureau International Database or UN DESA). The "live" births and deaths per second are statistically generated fluctuations around these averages to enhance the dynamic feel.
Ok, so you added high-frequency random noise to the estimated averages to make it feel more realistic. To me, this makes it feel less realistic.
Anyway, don't mean to gripe, this is a cool project!
Jane Street's kvetching about Millenium showed the spotlight and now everyone will be getting the hammer ("iss hamam mein sabh nange hain"). Jane Street was also dumb enough to do this during the General Election, so now Indian regulators have to do something. This plus the Adani prosecution is a quick win to restore confidence in SEBI.
Millennium and Citadel are both hedge funds, who do not engage in market making at all. They are most similar to other multi-strategy hedge funds like Balyasny or Point72.
You may be thinking of Citadel Securities, who are a market making firm and do engage in high frequency trading. Other large and well known HFT firms include Hudson River Trading, Tower Research, Jump Trading, Virtu, IMC and Optiver.
