## ChartMill

**Technical-plus-fundamental screener with 0–10 ratings, 302 preset strategy screens and point-in-time historical scanning.**

**Best for:** Swing traders and screen tinkerers who want technicals and fundamentals in one tool with preset strategies of famous investors — and do not need real-time data.

Strengths:
- Composite 0–10 ratings on both the technical and the fundamental side, all usable as screener filters
- Historical screening: run any screen as of a past date — rare in this class
- 302 preset screens modelled on named strategies: CANSLIM, Minervini, Zweig, Lynch and more
- Deep alerting: nine alert types, including saved-screen alerts across a watchlist

Trade-offs:
- All market data is 15 minutes delayed even on paid plans, and most screener fields update once a day
- Free-tier limits are undocumented — the credit-system page was removed from their docs
- European fundamentals cover only Xetra and Euronext; London and Nordic listings are price data only
- No mobile apps, and the standard monthly price is high for delayed data

## Koyfin

**Institutional-grade market data and global screening on Capital IQ and Morningstar feeds, at retail prices.**

**Best for:** Data-hungry global investors and finance professionals who want Capital IQ-grade fundamentals, estimates and macro in one affordable terminal — and who work inside the platform rather than exporting from it.

Strengths:
- Institutional data sources (S&P Capital IQ, Morningstar) with genuinely global coverage at retail prices
- Deep screening: 5,900+ criteria and separate equity, ETF, mutual-fund and SMA screeners with templates
- Full-spectrum alerts — price, technical, valuation-level and news — delivered to desktop, email and push
- One of the best-rated mobile apps in the category (4.9★ on iOS), actively updated

Trade-offs:
- No API at all, by the vendor's own admission — and that is a data-licensing constraint, not a roadmap gap
- Export is hollowed out: financials, valuation, estimates and growth columns cannot leave the platform
- Custom formulas work only as watchlist columns — you cannot screen on them
- Key workflows (model portfolios, more formulas, full history) climb quickly into the $79+/month tiers
