FlowAlgo vs Unusual Whales
Prices read from each vendor's public pricing page on 2026-10-21. OptionScout's numbers are the ones the product enforces.
FlowAlgo sells speed and simplicity: sweeps, blocks and dark-pool prints pushed as alerts, with little around them. Unusual Whales sells breadth: the same prints with years of history, GEX pages, heatmaps and institutional holdings. Price works against FlowAlgo unless its alerts are the whole of your process.
