On a phone
A laptop is easier. On a phone you save the bookmark by hand once, then use it the same way.
Android, Chrome
- Tap Copy bookmark code above.
- Bookmark this page with the ☆ in the ⋮ menu. Then open ⋮ → Bookmarks, press and hold the new bookmark, and tap Edit.
- Change the name to sebifill, replace the URL with the copied code, and save.
- Open the SEBI form. Tap the address bar, type sebifill, and tap the suggestion with the star icon, not the search suggestion.
iPhone, Safari
- Tap Copy bookmark code above.
- Tap Share → Add Bookmark and save it.
- Open Bookmarks, tap Edit, tap the new bookmark, rename it Fill SEBI form, replace the address with the copied code, and tap Done.
- Open the SEBI form, tap the Bookmarks icon, and tap Fill SEBI form.
What the bookmark does, in code
It runs only on SEBI's form, in your own browser. It sets the same dropdowns and radio buttons you would click by hand. It doesn't read your details, send anything anywhere, or submit the form. This is the entire script:
SEBI's public comment process is not a vote. Each answer above is a position on SEBI's proposal, and you're submitting it under your own name. Read the seven questions and change any answer you don't agree with. This is not investment advice, and QuantNifty is not a SEBI-registered Research Analyst or Investment Adviser. See our Terms.
