Research checklist for United States
Before relying on a broker, product, account, market-hours table, tax explanation, or platform comparison, verify the following items:
Which legal entity serves your country or residency status.
Which regulator supervises the firm or product.
Whether investor-protection coverage applies and what it excludes.
Whether the account type, product, or exchange access is actually available to you.
Whether costs include FX conversion, spread, custody, withdrawal, inactivity, platform, or tax-document fees.
Education and tool links
Model taxable/brokerage assumptions, dividends, futures or options scenarios, market returns, and fees only as learning scenarios. They do not decide suitability, tax treatment, state-specific rules, product permissions, broker access, or risk tolerance. Use the calculators to frame better questions for United States research, then compare the result with official guidance or qualified professional advice before acting.
