Flow Proof vs Market Chameleon
Market Chameleon is a deep options analytics platform known for volatility research, earnings tools, and screeners. Flow Proof is a free, narrower tool: a put-selling scanner that grades 25 stocks A to F, plus AI trade analysis and a trade tracker. Quick disclosure: I build Flow Proof. Both tools care about implied volatility, so this one is a more direct comparison than most.

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
Market Chameleon is the better research tool, full stop. If you want to dig into volatility history, earnings moves, and custom screens across the whole market, it's worth the $99/month.

How much does Market Chameleon cost?
Market Chameleon Premium is $99/month with a 7-day free trial. They offer a discounted yearly plan if you contact support. A free account gives limited access to some screeners and data.
Which is better for IV analysis?
Market Chameleon, by a wide margin. It has detailed volatility charts, IV history, and earnings vol analysis. Flow Proof shows 52-week IV Rank and IV/HV for its 25 scanned stocks and uses them to grade put-selling setups, which is useful but far narrower.
Is Flow Proof a free alternative to Market Chameleon?
For one job, yes: finding stocks worth selling puts on. Flow Proof grades 25 stocks A to F daily for free. It won't replace Market Chameleon's earnings research, market-wide screeners, or unusual volume reports.
Does Flow Proof track options flow like Market Chameleon's unusual activity screens?
No. Flow Proof doesn't show live options flow or unusual activity. It has free guides on reading options flow and unusual options activity, but the product itself is a put-selling scanner and trade tracker.
Which is better for beginners?
Flow Proof is simpler to start with: a graded shortlist, AI analysis on a symbol, and free guides on IV Rank, the Greeks, and cash-secured puts. Market Chameleon is more powerful but takes longer to learn.
