Flow Proof vs WhaleStream
WhaleStream is built to spot institutional "whale" options trades. Flow Proof is a free put-selling scanner and trade tracker. If you landed here looking for whale tracking, WhaleStream is the one of these two that does it. Quick disclosure: I build Flow Proof. It is not an options flow or whale tracking tool, so I'll be straight about where each one fits.

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 to follow whale options flow, WhaleStream does that at a lower price than FlowAlgo or Cheddar Flow Professional, and Flow Proof doesn't do it at all. If you're looking at whale flow because you want ideas for selling puts, you probably don't need it. Flow Proof's free scanner grades 25 stocks for put selling, and the blotter tracks the trade once you're in.
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.
