| What makes it different | - All figures sourced to their origin: filed statements with formulas and filing dates, or market data with its date
- Nightly re-testing of your investment thesis against new filings, with alerts only when guardrails break
- No investment advice, buy/sell recommendations, or fair value targets; you make all decisions
- Focuses exclusively on long-term investors who research companies; explicitly excludes traders and model-portfolio followers
| - Educational focus with no trading signals or recommendations, designed to teach users to test claims themselves
- Calculations independently verified against TradingView, TA-Lib and manual implementations
- Built-in Test Bench publishing original research studies with full methodology and negative results published transparently
- No look-ahead bias in backtesting: trades fill only at or after rule-triggering candle close
- User's Tiingo key and data never stored on GU Analyser servers, maintaining privacy
