Options Flow
The real-time stream of options market activity, tracked to identify unusual buying or selling patterns that indicate institutional positioning.
Options flow refers to the continuous stream of options transactions reported through OPRA (Options Price Reporting Authority) from all US options exchanges. Every options trade — from a retail trader buying a single contract to an institution placing a $10 million sweep order — is publicly reported and accessible in real time.
Options flow monitoring focuses on identifying activity that deviates significantly from a stock's historical norms: unusual volume relative to open interest, large dollar-value purchases, short-dated expirations, out-of-the-money strikes, and sweep routing (orders split across multiple exchanges for speed). When these characteristics combine on a single stock within a short time window, the signal is classified as unusual options activity (UOA).
Why Institutions Use Options
Institutional traders frequently express directional views through options rather than stock for several reasons: options provide leverage (a $50,000 options position can control the equivalent of a $500,000+ stock position), options define maximum risk (you can only lose the premium paid), and options provide privacy (a large stock purchase is visible in the public order flow; a large options purchase is less immediately visible to other market participants).
Reading the Signal
The most reliable options flow signals involve call sweeps (aggressive buying across exchanges) with short expirations (1–30 days), out-of-the-money strikes (indicating expectation of a large move), and high dollar values (indicating institutional scale). These characteristics together suggest a sophisticated participant believes a significant price move will occur within the expiration window — often correlated with a known or anticipated catalyst.
What TradeAI News Computes Instead
TradeAI News does not ingest OPRA transaction data, so sweep-level and block-level flow as described above is outside what it detects — that is what dedicated flow platforms resell. What it computes in-house from raw options chains and OCC open interest is implied volatility versus its own recent history, open-interest concentration by strike, and gamma-exposure structure. That context feeds the TMS score alongside the news catalyst and unusual-volume layers.
