Has anyone been able to successfully create a project that s/he runs on the side to predict stock prices? If so, what tech and what data did you use? And if not, could you share some of the learnings?
I do it to trade options successfully. I use technical analysis and it's definitely possible. It's not a side project, it's my income.<p>I only use PHP although the cool thing now is Python and has built in libraries. I don't need near instant execution and I started a long long time ago so rewriting everything is not something I want to undertake.<p>I use minute based data with all sorts of different indicators based on the stock, it's market, and competitors.<p>It's not something I think you can do as a side project as you have to refine it each day, I think if you aren't spending 8 hours a day looking at charts it will be hard to adapt/evolve.<p>Current stance is the market is bullish. I was bullish in December also.
Long back I tried something similar, but not successful.
Here it is in my Github:

The idea behind this project was to fetch information from twitter like social media sources and provide "popularity" info (not exactly stock price prediction) about stock of interest.
Sure they have. They used monkeys and a dart board.<p><a href="https://www.marketwatch.com/story/how-hedge-fund-geniuses-got-beaten-by-monkeys-again-2015-06-25" rel="nofollow">https://www.marketwatch.com/story/how-hedge-fund-geniuses-go...</a>
