How does this compare with the LEAN engine[1] and QuantConnect[2]?

Interesting choice to be using CPython. Very impressed with the completeness, and in particular the Risk Engine. Not having delved in too deeply yet, it does have the basics, but the markets are very highly regulated, and automated trading is always in the microscope. At Goldman, my team's whole job was to make sure the automated trading desks have all the checks implemented. It's a little spoilsport, but anyone seriously looking to use this, it's not gonna be very plug and play, at least while comlying with the market regulations.

I know FINRA has regulations but the CFTC proposed regulations were shelved. Are little guys who are not FINRA members encumbered by regulations here too?

A long time ago I figured out the difference between a Trader and Investor and realized I am very much the latter. After a few years this realization lead to my wealth increasing.

I just have to say your post starts out just like those bots do on youtube finance video comments, esp with the caps. I sorta felt like replying in their style to you really

Interesting stuff. I'm a bit confused on several points though.
If your strategies care so much about performance, can you really achieve the same or comparable performance with Cython? At that point, wouldn't those strategies be better suited for a custom "re-implementation"?
I suppose I'm not exactly sure how "high performance" and "low latency" this project is. Are there any latency stats on this project?

I wouldn't be surprised if this is sponsored by trading platform in order for customers to lose all money in record time...

I think the trading platforms earn more money if you make more trades. So it's in their interest that you trade for as long as possible.

I read it does exists trading platforms were if you earn money they lose it because they launched the order internally between their affiliates, and not to the external central trading computers (or whatever they are called). This if they even really launch the orders...
We can not see the traders' internal code so anything can happen. I think they look like money-collecting machines. Take care guys.
Edit: Wow, that downvote sounds very interesting, as the first that I pointed is widely known.

The website does say they're partners with OKX, nothing better than bringing more retail customers (that will promptly lose their money).
I've seen stats from other crypto exchanges that are something like "90% of the retail customers lose 90% of their funds in 90 days or less".

Trading platforms would make more money if you made just enough money to continue to trade long term. Especially the bucket shops crypto and forex exchanges that make most of their money front-running customer orders.
Unregulated exchanges are just a way to bring back the bad old days of "boiler room" penny stock scammers of the 80's. Most of the people making money are running 40 year old scams on 20 somethings who don't know better yet.
Finally, a way for me to lose all of my money automatically. What an exciting time to be alive!
More seriously, for anyone else who was curious below is a list of the existing integrations.
