Editorial Policy & Product Review Methodology

InvestorStack helps readers compare investing and trading tools. This page explains what our product pages mean, where the information can come from, and what readers should verify for themselves.

Research sources

A product page may combine official product documentation, public information, provider-supplied details, and InvestorStack editorial analysis. Direct product use is described only when it occurred and is relevant to the conclusion. We do not describe third-party ratings as ratings submitted by InvestorStack readers.

What we compare

The criteria depend on the product category. They can include features, supported platforms, pricing model, usability, support, integrations, free-plan availability, and relevant company details. Missing information is not treated as a product advantage or disadvantage.

Ratings

A displayed InvestorStack rating is an editorial score on a five-point scale. Where category scores are available, the page shows the factors considered, such as ease of use, features, value, and support. The overall score is an editorial assessment and may not be a mathematical average. It should be read together with the underlying facts, trade-offs, and the date the information was checked.

Pricing and changing product details

Prices, promotions, eligibility rules, and product features can change without notice. A price on InvestorStack is a reference point, not a quote or guarantee. Confirm current terms on the provider's website before signing up or paying.

Affiliate relationships

InvestorStack may earn a commission when a reader uses an affiliate link. Providers cannot purchase a positive score or conclusion. Read the full Affiliate Disclosure.

Corrections and updates

If you find an outdated price, incorrect feature, broken link, or a conclusion that is not supported by the page, please contact us. Include the page URL and the source supporting the correction. Material corrections should update the page and its verification date.

Financial information

InvestorStack provides general informational content. Product pages, comparisons, and educational articles are not individualized financial, investment, tax, or legal advice.
