Our Take
ChartMill: ChartMill is the most filter-rich affordable stock screener available, with over 180 filters, 29 chart patterns, 30 candlestick patterns, and proprietary ratings that no competitor replicates. Its coverage of European markets alongside North American exchanges makes it uniquely valuable for traders who operate across both regions. Charting is its weak spot — pair it with TradingView for deep chart analysis. If you trade patterns and want automated setup detection at a fair price, ChartMill deserves a place in your workflow.
Interactive Brokers: Interactive Brokers is the most comprehensive brokerage available for serious traders — delivering unmatched global market access across 170-plus markets, the industry's lowest margin rates, and professional-grade tools that scale from algorithmic strategies to multi-currency portfolio management. The learning curve is real but shrinking with IBKR Desktop. If low costs and global reach matter more than hand-holding, this is the broker to beat.
Pricing Comparison
ChartMill Pricing
ChartMill's pricing structure is notably flexible. The free tier provides 6,000 credits per month — enough for roughly 80 screener runs or 12 analyzer reports — with unused credits rolling over up to a maximum of 60,000. Casual screeners who run a few scans per week may never need to pay. When credits run short, a top-up of 10,000 credits costs 10 dollars. The monthly subscription removes all credit limits at 34.97 dollars per month, while the annual plan brings the effective rate to roughly 25 dollars per month at 299.97 dollars per year — a 29 percent savings. An introductory offer of 13.97 dollars for the first month lowers the barrier further. Compared to Finviz Elite at 39.50 dollars monthly or Trade Ideas at over 150 dollars, ChartMill delivers more screening filters and European coverage at a lower price point. The trade-off is the lack of real-time data, which Finviz Elite provides.
Interactive Brokers Pricing
Interactive Brokers operates a two-tier model. IBKR Lite provides genuinely commission-free trading on US-listed stocks and ETFs with no account minimum — funded through payment for order flow. IBKR Pro offers two pricing structures: Fixed at $0.005 per share with a one-dollar minimum, or Tiered starting as low as $0.0005 per share based on volume. Options cost $0.15 to $0.65 per contract on the tiered plan, and futures run $0.85 per contract. Margin rates between 4.14% and 6.14% are the lowest in the industry. Pro accounts earn interest on idle cash at the benchmark rate minus 0.5%, currently up to 3.14% APY for balances in accounts with $100,000 or more in net asset value.
What Users Say
ChartMill
User sentiment toward ChartMill is positive but quiet — the platform has a smaller public footprint than competitors like Finviz or TradingView. Across blog reviews, it consistently earns ratings between 3.8 and 4.2 out of 5, with praise centered on screening versatility, the proprietary Setup Rating, and the breadth of pre-built screens. On Trustpilot, ChartMill holds a 3.4 score from seven reviews. One reviewer called it "by far the best filter from my experience," comparing it favorably to BarCharts and Finviz. Another described it as "a great research tool for swing traders." The negative feedback clusters around pricing relative to the lack of real-time data and limited API access — one reviewer noted the platform was "technically limited (no Excel API)" for their needs. The small review sample reflects lower brand awareness rather than poor satisfaction, and the absence of any one-star reviews on Trustpilot suggests the platform delivers on its core promise for those who discover it.
Interactive Brokers
Professional review outlets rate Interactive Brokers very highly — StockBrokers.com awards a perfect 5 out of 5 stars, and Benzinga gives 4.5 out of 5. The picture shifts on consumer platforms, where Trustpilot shows a 3.5 out of 5 across more than 5,100 reviews. The divide reflects a consistent pattern: experienced traders praise the low costs, global access, and powerful tools, while less technical users struggle with interface complexity and customer service responsiveness. Common positive themes include appreciation for competitive margin rates, breadth of tradeable assets, and the reliability of the platform over years of use. Negative themes center on account verification difficulties, slow support response times, and occasional platform login issues.
Choose ChartMill if...
- → Swing traders and pattern-focused investors who screen US and European stocks
- → ChartMill is built for swing traders and position traders who screen stocks regularly and want a tool that goes beyond basic filtering.

Value investors will appreciate the Piotroski scores, ROIC variants, and sector-relative percentile rankings that put companies in context against their industry peers. Growth and momentum traders benefit from the pre-built screens modeled on strategies from William O'Neil, Peter Lynch, and Mark Minervini. European traders gain a meaningful advantage here, as ChartMill covers Euronext, Xetra, and the LSE — markets that Finviz ignores entirely. Casual screeners who run only a few scans per week can use the platform effectively without paying, thanks to the 6,000 monthly credit allowance.
Choose Interactive Brokers if...
- → Active traders, global investors, and algorithmic traders seeking the lowest costs and broadest market access

Options strategists get dedicated tools like Volatility Lab, Probability Lab, and Option Lattice.

Portfolio managers tracking multi-asset, multi-currency holdings across global markets will also find the PortfolioAnalyst and Tax Planner tools indispensable.
