I would strongly recommend building something that you yourself think is cool, and not feeling that you have to conform to what other people tell you to do.
As someone who has played with writing trading bots but never traded them with real money, some advice: if your results seem too good to be true, they probably are. Your trading bot may be doing unrealistic things or its results may not be reliable if the following are true: - You are trading in a market with low liquidity or one that is controlled by a small number of market participants. I'm not an expert but I thi…
Replace widget with liquidity and factories with traders and you should immediately see why most traders are losing money. They are operating in markets where their liquidity simply isn't needed.
If you want to make money off of trading then you have to find a market with low liquidity where having more traders is actually welcome but why do hard work if you can just invest your money and still get good gains without working?
Earlier quoted context omitted.
I tried making a bitcoin trading bot and almost all of the money (about 10 bucks, not no big problem). My main mistake was using the historical trades instead of the historical offers as a testing dataset.
did it work at the end? I want to make a crypto trading bot seems simpler than stock one
This article is aimed towards students. It's great advice for students who are in college, know very little, and want to improve their CS skills. It's poor advice for someone who already has a STEM degree and wants to build something useful and profitable. If you already know how these things work, your time is better spent on the "edge of the circle": http://matt.might.net/articles/phd-school-in-pictures/ which appl…

I worked on a unique HFT system which was capable of starting the response packet before the incoming packet's final byte had arrived. Negative latency. If it mispredicted the future, it would simply scramble the trailer and cause the packet to fail UDP checksum. It didn't make money in the real world because the quality of decision that could be made at that speed wasn't good enough.
Failing the checksum was sort of common as well, but exchanges don't like it.
These days most tricks have to do with avoiding as much serialisation time as possible, e.g. by sending ahead part of the TCP payload and filling in with some innocent order if there was no opportunity.
What do folks think about implementing a web crawler that you can send to a website and it indexes every internal url on the site. I remember sitting down to write one 100 years ago now, and finding it to be much trickier than I thought it would be.

You should grow a second spike. I'm at the point where visual design skills are a greater bottleneck than my computer science skills. I can build purely functional CAD models but man, making them functional AND look good is the real challenge.
How about designing your own virtual memory system

Which is why lists like this help.

that's interesting. grab only the URLs, not the content?
