China Lens

About

China Lens shows you the Hong Kong "shadow price" behind Chinese ADRs — without leaving TradingView or Yahoo Finance.

When you open a covered Chinese ADR (like Alibaba/BABA, JD, NIO, Bilibili, PDD and more), a side panel shows:

• The Hong Kong listing's price (the cross-listed shares)
• The ADR/HK premium or discount, auto-calculated from the verified ADR ratio and a live USD→HKD exchange rate
• China-market context — southbound fund flow, or sector-proxy ETFs for names without a direct cross-listing
• Every number's source and delay, shown plainly

Why it exists: investors holding Chinese ADRs usually pay for an expensive terminal, or juggle several browser tabs, just to compare the US listing with its Hong Kong / mainland counterpart. China Lens puts that comparison inside the workflow you already use — for free.

v0 covers 20 hand-curated Chinese ADRs and only activates on TradingView and Yahoo Finance.

Privacy: China Lens reads only the ticker symbol on the page, only on those two sites, to look up public market data. No accounts, no cookies, no browsing history, no analytics, no tracking. See the privacy policy for details.

Note: prices may be delayed and are for reference and comparison only — not for order execution.
