Ownership signals from shareholding, pledges and filings

[iamsaquib8]

An idea, not planned yet. Track changes in promoter, FII and DII holdings and pledges from NSE's quarterly shareholding filings, follow well-known investors' disclosed holdings, and alert on phrases in filings (for example "resignation of auditor"). insights already reads some of this data. Must stay factual: show changes, never a buy/sell call. Comment if you would use this.

Moved from issue #274 to keep the issue tracker for scheduled work. Upvote or comment if you would use this; ideas with demand go back on the roadmap.
