How we source data

Every date on Tickalyst comes from National Stock Exchange of India (NSE) records, and each event links to the filing it came from.

Where the dates come from

• Dates and terms come from NSE's published list of corporate actions: ex-date, record date, and the amount or ratio.
• The filing link points to the company's own announcement to the exchange: the board's declaration or its record-date notice, as a PDF on NSE's site. Where no matching announcement is found, the link goes to the company's NSE page.
• The company list is the Nifty 500, with NSE symbols and ISINs from NSE and BSE scrip codes from BSE's daily market file.

How often it is checked

The data is refreshed several times a day. Each upcoming event shows when it was last checked.

When a date changes

Companies sometimes move an ex-date or record date. When that happens the event is labelled Date revised, and the company page says what moved and when. We keep every past version of each event.

What we do not publish automatically

If an announcement cannot be read with confidence, for example an unusual ratio or a scheme of arrangement, nothing is published until it has been checked by hand.

What Tickalyst does not do

• No buy, sell or hold recommendations and no price targets.
• No stock prices.
• No grey market premium figures, which have no official source.

Always confirm a date in the linked filing before acting on it. If you find an error, please report it.
