Best Cheap Options Flow Scanners
You don't need $149/month to see options flow. Several tools have free tiers or cost well under $100. Here's an honest list with what each one costs. Quick disclosure: I build Flow Proof. It is a free put-selling scanner, not a flow scanner, so it isn't on the flow list. I mention it at the end for people whose real goal is selling premium.
Feature Comparison
About Multiple
Lower-cost flow options include Unusual Whales (free tier with delayed data), Tradytics (about $50/month, free account with delayed data), WhaleStream (about $69/month), and Quant Data (about $75/month per third-party listings). For comparison, Cheddar Flow is $85 to $99/month and FlowAlgo is $149/month.
Pricing: Free tiers (Unusual Whales, Tradytics) up to about $75/month for the cheaper paid flow scanners. Real-time data usually needs a paid plan.

Why Choose Flow Proof Over Multiple
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
Start free with Unusual Whales or a Tradytics free account to learn what flow looks like. If you want real-time data on a budget, Tradytics (about $50/month), WhaleStream (about $69/month), and Quant Data (about $75/month) are all well under FlowAlgo's $149. If what you're really after is income from selling puts, you can skip flow entirely. Flow Proof's scanner and trade blotter do that 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.

What is the cheapest options flow scanner?
Unusual Whales has a free tier with delayed data, and Tradytics has a free account with delayed data. For real-time flow, Tradytics at about $50/month is one of the cheaper paid options.
Is cheap options flow data reliable?
The underlying trades come from the same exchanges whatever you pay. What changes is speed (free tiers are delayed), filtering, and extras like dark pool data. Delayed data is fine for learning, less so for trading off it.
Is Flow Proof a free options flow scanner?
No. Flow Proof is a free put-selling scanner. It grades 25 stocks A to F for selling puts and tracks your trades. It has no flow feed, sweep alerts, or dark pool data.
Do I need a flow scanner to sell puts?
No. For selling puts, IV Rank, IV/HV, the chart, and your strike and size matter more than who bought calls this morning. That's the job Flow Proof's free scanner is built for.
