I wrote a bot that watched twitter for stock symbols and then applied a social sentiment index based on the tone of the tweet. The historical stock quotes were downloaded, and the stock was added to a polling system to capture future quotes. The social sentiment could then be turned into an indicator to determine when to buy/sell especially if used with other indicators.
Well I forgot about the system then twitter changed their api rules. When I went back it had captured data for 2 years. I backtested the trades and I found that it sucked for indexes/etfs, worked mmokay for pop stocks (think Tesla, bynd, suneq) but really shined for pump and dump stocks. With Twitter out I added stocktwits, Reddit, and tradingview. I now have twitter again and all of these feeds are run on various dedicated servers feeding into a mothership
NB: the system was originally written for a stock pumper who disappeared after a month of development
