InsiderWire is an automated tracker that pulls stock-market signals from several independent sources and flags the ticker when they line up. It does not give investment advice — it surfaces clues. You decide what to do with them.
We pull stock-market activity from multiple sources throughout the day — corporate insiders buying their own stock, mega-fund 13F filings, U.S. Congress trade disclosures, and social chatter. Everything lands in one feed, and when the same ticker shows up across sources — or piles up inside one source — we send Pro users an instant push notification.
The thinking is simple: one buy might be a guess. But five insiders buying the same ticker in a week, or a CEO buy landing the same day Congress is also buying — something is happening. That's the kind of signal you don't want to miss.
Public, freely available data — polled automatically every few minutes. No paid feeds.
When a CEO, CFO or board member of a US-listed company buys shares of their own company, they have to file a Form 4 with the SEC. OpenInsider aggregates those filings into a clean, searchable feed.
Why it matters: insiders know their company better than anyone else. When they put their own money in, they're saying "I think this stock is going up."
openinsider.com →Warren Buffett (Berkshire Hathaway), Ray Dalio (Bridgewater), Bill Ackman, Tiger Global and other billion-dollar funds disclose their portfolios quarterly via 13F filings. Dataroma turns the raw data into a clean buys/sells table.
Why it matters: these investors move markets. Their decisions are typically the result of deep research.
dataroma.com →Members of Congress are required to file Periodic Transaction Reports within 45 days of any trade. We pull them from the House Clerk and the Senate eFD (Electronic Financial Disclosure) systems — both chambers, both buys and sells.
Why it matters: politicians often sit on committees that touch the companies they trade. The disclosures are noisy but occasionally informative — see the Reports page for the actual hit-rate data.
Stocktwits is a social platform for finance-focused users. They publish a real-time list of trending tickers. We pull the US tickers from that list.
Why it matters: this doesn't tell you direction (up or down), but it tells you about attention. Where there is attention, there is movement.
stocktwits.com →Not every blip deserves a notification. The consensus engine groups signals on the same ticker inside a rolling window (default 7 days) and fires one of three event kinds:
Each event gets a score. Higher score = more and fresher evidence. The formula multiplies a per-source quality weight by a logarithmic same-source curve (5 buys score more than 1, but not 5×) and an average recency multiplier (today's buy worth more than last week's), then adds a bonus when several distinct sources agree. Every knob — half-life, curve shape, source weights, push thresholds — lives in config.ts and can be tuned without code changes.
The Quality page reports per source:
The Reports page goes deeper for Congress and Insiders specifically — leaderboard of which politicians / which tickers had the best follow-through, with the full trade detail underneath.
The Backtest page (Pro+) is the scoreboard for the whole system: in plain terms, after each signal fired, did the stock actually go up — and by how much? For every source it shows the win rate (how often the price was higher 1, 7, and 30 days later) and the average move. It's the honest track record — proof of which signals tend to work, not just a promise that they do.
These numbers only become meaningful with time — don't trust a one-week sample. After a few months of accumulated data it becomes clear which source is actually pulling its weight.
Free shows the trending feed (Stocktwits) for the last 24 hours — enough to see what the app feels like.
Pro unlocks the rest: insider buys, 13F moves, Congress trades, 90-day history, the values screen (halal / sin-stock / debt filter), consensus events, Slack alerts, and instant push notifications when a high-scoring event fires.
Pro+ adds the Backtest scoreboard — the historical win rate and average return for each signal source — plus priority support.
