A screener narrows a universe; it does not decide for you
A stock screener filters a list of securities according to chosen criteria such as exchange, liquidity, industry or financial metrics. It is an efficient starting point, but a matching filter is not evidence that a company is suitable or that an investment will rise in value.
Brokerage and research tools solve different jobs
A broker handles account services and trade execution under its applicable permissions and terms. Research products may focus on fundamentals, charting, analyst estimates or portfolio analysis. A trading journal records actual decisions and outcomes. Some platforms combine these roles, but the data, fees and export limits still deserve separate scrutiny.
- Discovery: screening rules and coverage
- Research: financial data quality, updates and sources
- Execution: available markets, costs and order types
- Review: journal imports, reports and export rights
Compare data freshness before comparing subscriptions
Free datasets and lower subscription tiers can be sufficient for historical research but unsuitable for time-sensitive trading decisions. Examine update frequency, available exchanges, corporate-action adjustments and whether data can be independently checked.
Keep a reproducible decision record
Save the criteria used to identify a company, the sources used to examine it, and the reason a trade or investment was considered. TradeOffr can help compare tool capabilities, but does not replace financial advice or the broker’s official terms.
Use this guide as a framework for research. Provider-specific facts shown in TradeOffr comparisons are published through the official-source verification gate; unresolved changes stay out of the public comparison.
