Methodology & data
Every score comes from rules you can see and change in the editor. Even AI drafts stay normal, inspectable rules.
Index compositions are applied survivorship-bias-free; earlier periods are marked accordingly.
Fundamentals and prices from a single source, updated daily.
Simulations on historical data are not a guarantee of returns and not investment advice.
Nothing happens automatically: since we never ask for payment details, the trial simply ends and your account continues as Free.
Yes, everything stays saved and nothing is deleted. Items above a Free limit are locked (lock icon): in each area, the entries you created first stay usable within the limit. You can delete locked entries anytime or unlock them again with Premium.
No. A backtest is a model simulation on historical data. Useful for checking rules, but not a statement about the future and not investment advice.
Yes, anytime in your account. When switching to yearly, the month you already paid for is credited proportionally.
