Who cares about how many hours of work they are putting in. As long as tasks are getting done on time, it shouldn't matter what I am doing with my "hours".
Can you talk more about this? I personally have a Dell R720 and about 90TB available for use, and use 40TB of it for my media server. I'm wondering if that's some use case I want to look into.
DISCLAIMER: I don't really know what I'm doing. My knowledge of trading basically amounts like a few Coursera classes.
I wanted to play with paper trading strategies. I listen on websocket streams of cryptocurrency and stock ticker stuff [1], and the service listening on that socket just plops it into Kafka, with the partition key being the ticker name.
The reason I bother adding Kafka largely comes down to the ability to use the Kafka Streams API. Kafka Streams allows me to do time windows of different trades, or lets me do a sql-style join across two different streams, or lets me filter out data that I don't think is relevant.
Kafka Streams gives you most of the fun of a map-reduce framework, but without having to administer a map-reduce server; it's even smart enough to handle internal state by creating intermediate topics and/or creating local RocksDB instances. It's pretty cool.
There's also has the advantage of allowing me to set retention, so I don't have to worry about doing any kind of manual cleanup; I only have to worry about having N days of stuff on the server, and it's trivial to change that.
Also, I have a number of topics, each with 32 partitions, meaning that if I do find any kind of strategy that works, I can very easily scale it up without changing any code.
I'm basically using Kafka as a streaming-only database. I think it's neat but I haven't actually found any strategies that make or lose money. It's just been a fun way to play around with different bits of server stuff.
Awesome! Yeah, seems like a great learning opportunity. I did 2 Coursera courses during Covid of trading as well, but didn't touch it after creating one strategy, mostly using RSI, Moving Avg etc lol. Will give this a try, thanks.
Yeah, I had no delusions I would become a billionaire from anything I did. I just find that I learn stuff better if I have a direct goal instead of just dealing in abstracts.
I can read about all the fun theory behind trading math and for distributed systems, and that has some value, but I will understand stuff a lot better if I give myself a real project to do stuff with. I guess I am more of an engineer than a mathematician.
