Every market headline, placed next to what the institutional money actually did on that ticker. Dark pool share, max pain, call wall and put floor, put/call ratio and the day's options flow — numbers that normally sit behind a professional terminal. When the story and the money point opposite ways, we mark it. 595 US tickers. 2–3 editions a day. English, Korean, Japanese. Free, no account, no paywall. Information and education only — not investment advice.

Hi Product Hunt 👋 I kept hitting the same wall. A headline says a stock moved on some news — but the numbers that tell you who was actually on the other side of that trade (dark pool share, where the options open interest is stacked, whether the flow was calls or puts) sit behind terminals that cost more per month than most people's rent. Undercurrent puts both on the same card: the headline, then what the money did on that ticker that session. When the two point opposite ways, we mark it — that's the "divergence" tag. Free, no account, no paywall. 595 US tickers, 2–3 editions a day, in English, Korean and Japanese. Two things I'd genuinely like feedback on: 1. Does the divergence mark read as useful, or as noise? 2. The data is dense — is the plain-language read enough, or do you want the raw numbers first? Happy to explain how any of the metrics are computed. (Information and education only — not investment advice.)

We tracked every time the news and the money disagreed. The money is losing.

I build a free app that puts each market headline next to what institutional money actually did on that ticker dark pool share, options positioning, flow. When the story and the money point opposite ways, we mark it a divergence.

The uncomfortable part: we score them. Three days after every divergence, we check who was right and the running tally stays on screen where anyone can see it. As of this morning it reads: money 36, news 42, draw 62.
