TradeHouse FlowAlerts · Buyer resources
Unusual options-volume checker
Live options order-flow alerts built on a forward Alpaca OPRA tape: sweep detection, large prints, dollar-signed put/call skew and unusual-volume ratios. Tiers are Free, Pro $29 and Premium $79 (Premium is bundled with Desk).
Ratio = current volume / 20-day average volume for the same contract. A high ratio does not establish trade direction or profitability.
