Notes and risks
The maintainer opened the link in a browser on 2026-10-24; whether the code is accepted at sign-up was not tested. Redeeming needs a login, and per the platform's help page the website currently supports Google login only; Tide may change or end its invite rules at any time. Tide is a market-information tool; its own terms say it is not a securities investment advisory business and its content is not investment advice. The operator is described inconsistently: the terms name an individual operator while the footer names 潮汐資訊有限公司, and this site could not verify a company registration. The privacy policy asks users under 18 to have a legal guardian read and agree to it first.
