Usage Tips

How reliable are analysis ratings based on the Gann Square of Nine?
The reliability of Square of Nine analysis is significantly disputed in both academic and practitioner circles. Proponents claim that price levels calculated from the Square of Nine frequently align with actual support and resistance levels, but critics argue this is primarily a probability effect—when you project enough geometric relationship price levels from a single number, some will inevitably come close to actual turning points. The lack of large-sample statistical validation is the Square of Nine's greatest weakness. Analytical ratings have some value in showing how well Square of Nine calculated levels match historical prices, but investors should not treat it as a high-precision prediction tool. It is recommended to treat Square of Nine derived levels as reference areas worth monitoring, seeking confirmation from other technical signals near these areas rather than blindly placing orders at these prices.

Getting started

Does this prompt give investment advice or buy/sell calls?
No. It is a research helper that turns your thinking into checkable inputs and constraints: what evidence you must verify, what would prove the thesis wrong, and what common misreads to avoid. Treat the output as a draft, not a signal. Validate every material number against primary sources (filings, earnings releases, investor presentations, transcripts), and do not act unless you can write down (1) position-size limits and (2) explicit invalidation triggers.
What inputs should I provide for a reliable result?
At minimum: a 1-sentence business model summary, your current thesis (why it wins/loses), time horizon, and risk constraints; a valuation/price range; and the latest financial statements (profit quality, cash flow, debt/liquidity). Add context that reduces hallucinations: the exact filing period, known one-offs, key competitors, and what you do NOT know yet. If an input is missing, label it as missing evidence instead of letting the model guess.

Validation and boundaries

How do I validate the output?
Validate falsifiable claims one by one. Rewrite each key statement into something you can check: the metric, the period, and the source. Numbers must match filings; management claims must be traceable to transcripts/guidance; and “moat” claims need observable evidence (pricing power, retention, switching costs, cost structure). Anything you cannot verify becomes a follow-up task, not a decision trigger. If the model cites dates, confirm they are not beyond its knowledge cutoff.
When should I NOT act on the output?
If you cannot write down invalidation triggers, a position-size cap, or primary-source evidence for the key claims behind “Carré de Neuf”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
