How it works

In real-time, dxFeed Unusual Options Screener pairs options time, price, size, bid, ask, open interest, daily volume, and more with the stock price, trade volume, and other data. The screener filters out the noise so users can follow the smart money.

dxFeed Unusual Options Screener integrates real-time, high-quality price feeds provided by dxFeed, and uses dxScript, the company’s proprietary scripting language, to define the specific unusual event criteria to be screened for with pinpoint accuracy. On top of that, it also incorporates dxFeed advancements in applied machine learning in finance, and provides an ML calculated unusualness score.

Artificial intelligence-powered filtration

dxFeed’s research team conducted a machine learning study with unsupervised learning to identify unusual trades. For an option sale, one can define its potential profit as execution at maximal (for a call option; or minimal for a put option) underlying price over the lifetime of the option. The research was aimed at filtering out options with revenue magnitudes bigger than the paid premium. Trained over a sample of trades data, the final model has the area Under the ROC curve score at 0.99!
