![]() The company plans to double down on these predictive smarts. OpenBB: Natural language processing (NLP) is used to correlate the impact of news headlines on companies’ share pricesĮlsewhere, OpenBB can leverage deep learning to predict stock price movement using historical data, though in reality the model can be applied to just about anything, including economic data, crypto, and more. For example, it can look at Apple’s share price over the past week, and then grab news headlines via one of Finnhub’s APIs and derive sentiment from each headline using natural language processing (NLP), and then correlate the impact of news on Apple’s share price. OpenBB leans on machine learning across myriad use-cases. The platform gleans its investment data via publicly available sources, among others that require an API key - these include Alpha Vantage, Financial Modeling Prep, Finnhub, Reddit, Twitter, Coinbase, the SEC, and many more. In its initial guise, OpenBB is deployed via a command line interface (CLI), though plans are afoot to build a proper GUI for regular users. It’s pitched as a “Python-based integrated environment for investment research,” allowing any trader to access data science and machine learning smarts to unpack raw, unrefined data. The newly named OpenBB Terminal is very much an alpha-stage product, one that’s aimed at the more technically minded.
