Editorial Policy
Our standards for accuracy, independence and how we handle corrections.
Accuracy and review
Content is drafted from exchange documentation and established options theory, and reviewed before publication. Each page carries a last-reviewed date and an explicit reminder that exchange conventions change. We distinguish clearly between exchange rules, mathematical facts and rules of thumb.
Independence
ExpiryGyan is independent and educational. We do not accept payment to promote brokers, products or securities, and no page is a recommendation. Any future affiliate links or sponsorship will be disclosed clearly on the relevant page.
Corrections
We fix errors promptly — especially when an exchange changes a rule. If you spot a mistake, tell us via the contact page; material corrections are noted with an updated review date and, where relevant, in our update history.
No investment advice
Nothing on ExpiryGyan is investment, trading, legal or tax advice. We are not SEBI-registered. See the SEBI Disclaimer and Risk Disclosure.
