Would you use a Chrome extension that shows mainland China data when you're viewing Chinese ADRs?

Most of us here hold BABA, PDD, JD, NIO, LI through US ADRs. But the real signal often lives on the mainland — northbound capital flow, A-share supplier prices (CATL, BYD), regulatory filings — and most of it is

   in Chinese.

  I'm a Chinese developer scratching my own itch. Idea: a Chrome extension that adds a side panel in TradingView / Yahoo Finance with:

  \- Mainland / HK dual-listed price

  \- Northbound capital flow (5-day net inflow)

  \- AI-translated earnings call highlights

  \- Recent CSRC / HKEX / SEC 8-K filings (translated)

  Pricing thought: free basic, $4.99/mo for the deep stuff. First 100 get lifetime Pro.

  I'd rather validate before coding. Two questions:

  1. Do you currently cross-reference any mainland data when trading these ADRs? Or is it noise?

  2. Is $4.99/mo reasonable, or should it be one-time / free-with-ads?
