Buying guide

  1. Demand a ranked shortlist (UOA-style), not only a scrolling tape—that is what “scanner” should mean.
  2. Require side/aggressor, premium, trade-type (block/sweep), and DTE filters at minimum.
  3. Prefer tools that connect option flow to chain structure (OI/walls/GEX), not tape alone.
  4. Check impact metrics (e.g. DEX/DEI) so large OTM lottery tickets do not dominate the list.
  5. Trial with your real watchlist for at least one full session.
  6. 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.
