TradeHouse FlowAlerts · Buyer resources

Best unusual options activity scanner?

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).

Choose a scanner by coverage, timestamp precision, filtering and alert delivery rather than a universal ranking. Test the same contracts across tools, separate volume from open interest, and check how multi-leg trades are represented. FlowAlerts exposes sweep, large-print and unusual-volume signals.
