What it does
FlowAlgo is an options and equity order-flow service that distinguishes sweeps, blocks and off-exchange prints. New subscriptions and trials are paused. The company plans to stop new data on 30 October 2026 while rebuilding the service, with a relaunch targeted for the first quarter of 2027.
FlowAlgo’s current access notice comes before its older plan advertising: new customers cannot subscribe or start a trial. New flow, blocks, prints and alerts stop after 30 October 2026. Existing accounts retain access to already collected data until 13 November, free of charge. The planned 2027 relaunch has no fixed date or published new prices.
For existing users reviewing the data, SWEEP marks an order consolidated across multiple exchanges; SPLIT refers to a sweep on one exchange. The help guide describes the options alert feed as ask-side activity and says it excludes trades at the bid or midpoint. Equity blocks require separate interpretation because each transaction has both a buyer and seller. A large print alone does not reveal the surrounding position.
FlowAlgo Levels groups historical block and off-exchange volume by price. Its displayed strength comes from the amount traded at that level, which is different from knowing that a future price will hold there.
Subscriptions cancel automatically on 30 October. The announcement says unused paid time will receive prorated refunds to the original payment method. Members who want to cancel earlier can use the cancellation link on their account page.
