They solve different problems, so this page is about helping you figure out which one you actually need. Quick disclosure: I build Flow Proof. It is not an options flow tool, so I'll be straight about where it does and doesn't replace Quant Data.

Why Choose Flow Proof
The Wheel Strategy Cycle
Each phase generates income. Assignment isn't a failure — it's the transition to the next income-producing phase.
The wheel strategy generates income at every phase. Phase 1: sell a cash-secured put and collect premium ($150-400/month on a typical $50 stock). Phase 2: if assigned, your cost basis is the strike minus all premiums collected. Phase 3: sell covered calls against your shares to collect even more premium. Phase 4: when shares are called away, you've profited from the put premium, call premiums, and any stock appreciation. Then the wheel restarts.
The Verdict
If you want a clean flow scanner with sweep detection and dark pool prints, Quant Data is a reasonable pick for less than FlowAlgo. Flow Proof doesn't do flow. If your real goal is selling puts or running the wheel, Flow Proof gives you a graded scanner, AI analysis, and a trade blotter for free.
Flow Proof Is Free
Put premium scanner with A to F setup grades, AI trade analysis, and a trade blotter with roll advice. No credit card required.
