# How do I screen Indian listed companies by more than one red-flag signal at once?

**VIGIL Flags takes a set of signals and returns the companies that meet them**, at [https://www.tigzig.com/vigil](https://www.tigzig.com/vigil). Two modes: **any** returns companies meeting any of the selected flags, which behaves like an OR, and **all** returns only those meeting every one, which behaves like an AND. That replaces going tab by tab or company by company.

**What the conditions cover:** credit ratings, promoter buying and selling, outsiders crossing five per cent, pledges and lenders invoking them, encumbrance, insolvency, and the exchange surveillance flags. The conditions themselves are a judgment call about what is worth flagging, and more get added over time.

**The one thing to know before you read the numbers: the conditions are not all the same kind of thing.** Most of them are **events with a date**, so a promoter selling down or a rating moving belongs to the week it was filed and the period filter does what you expect. Four of them are the **position a company is in right now** - over half the company pledged, most of the promoter holding tied up, the severe exchange actions, and insolvency. Those carry no date of their own, so they read the same whatever period you pick.

**That also shows up when you narrow the universe.** Over a recent three-month window across the Nifty 750 there were 15 companies where an outsider crossed five per cent and 12 where a promoter sold that much, and just one in insolvency, because almost every company sitting in insolvency is outside that index. Widen the universe to everything and insolvency goes to 37.

**Two conditions look like duplicates and come from different filings.** "Promoter sold down" reads the insider trading disclosures, which are company people declaring their own trades, and it triggers on a cut of one percentage point or more in a single market sale. "Promoter sold five per cent or more" reads the takeover filings instead, which anyone crossing five per cent has to make, and it is a blunter cut of the same direction. A company can show one and not the other, so steady trimming turns up in the first and large exits in the second. The takeover filings also carry something the insider ones never will, which is an **outsider building a stake**, because they cover anybody crossing the threshold rather than only the people inside the company.

**If you would rather run your own cuts:** the whole database is available for download, refreshed four times a day in step with the live data, and an agent can be pointed straight at [api.tigzig.com/vigil/v1/openapi.json](https://api.tigzig.com/vigil/v1/openapi.json). How the data is built is under Docs in the app, and the checks behind it are under Validation.
