Best FlowAlgo alternatives in 2026 (FlowAlgo is offline)
FlowAlgo tracked options order flow: intermarket sweep orders, option block trades, and equity blocks and dark pool prints, with intraday voice alerts. FlowAlgo's plan page says it went offline on October 30, 2026 while it rebuilds its data pipeline, and that it will open sign-ups again in Q1 2027, when the all-new FlowAlgo launches. It isn't taking new subscriptions or trials right now. If you need options flow in the meantime, here are 8 alternatives we track, with prices checked on each tool's own site.
What happened to FlowAlgo (checked 2026-11-09)
According to FlowAlgo's plan page:
- New customers: FlowAlgo isn't taking new subscriptions or trials. Plans and pricing for the new platform will be announced before launch.
- Current members: subscriptions were canceled automatically on October 30, with prorated refunds to follow.
- Relaunch: Q1 2027. FlowAlgo says existing members will hear the launch date first, by email.
FlowAlgo's homepage still shows its old offer (a 2-week trial for $37, then $149/month), but the plan page says sign-ups are paused. We'll update our FlowAlgo listing when it reopens.
