Buying guide
- Demand a ranked shortlist (UOA-style), not only a scrolling tape—that is what “scanner” should mean.
- Require side/aggressor, premium, trade-type (block/sweep), and DTE filters at minimum.
- Prefer tools that connect option flow to chain structure (OI/walls/GEX), not tape alone.
- Check impact metrics (e.g. DEX/DEI) so large OTM lottery tickets do not dominate the list.
- Trial with your real watchlist for at least one full session.
- Price is secondary to whether you will actually use the rank→tape→structure loop daily.
Frequently asked questions
- What is an options flow scanner?
- A scanner ranks and filters unusual options prints so you inspect a shortlist instead of every tick. In TradingFlow, Rank builds the shortlist and Option Trades is the filtered live tape; chain drawers validate walls and OI.
- Option flow scanner vs options flow tools—what is the difference?
- Searchers use both phrases. The product job is the same: discover unusual flow, filter the tape, validate structure. This page ranks tools on that loop.
- Why is TradingFlow listed #1?
- Because this site builds TradingFlow: we recommend it where the rank→tape→chain workflow matches. We still list peers so you can trial alternatives on the same criteria.
- Do I need options flow tools for investing?
- Not for long-term buy-and-hold. Flow scanners help active options and short-horizon equity traders more than passive investors.
