See the move before the crowd sees the story.
WhaleWatcher scans live market activity, large-print flow, insider filings, and historical patterns, then turns the noise into clear research signals you can inspect and paper-test.
It watches unusual market activity, explains the evidence, then tracks what happened next.
WhaleWatcher is a research system built to help members notice unusual activity faster and investigate it without guessing. It combines live large-trade flow, repeat activity, Whale Score, SEC and insider context, historical behavior, alerts, replay tools and paper simulation in one place.
The system scans live market activity for unusually large prints, repeat activity and accelerating flow. Names can move from Watching to Heating Up to Whale Detected as evidence builds.
Whale Score and Why Now? show what contributed to the alert, what is confirmed, what is inferred, and what could invalidate the setup.
Check SEC and insider activity, historical trends, previous whale events and follow-through instead of relying on one flashy signal.
Use the paper simulator and recorded signal history to test ideas with fake money and review results before considering any real-money decision.
Built to watch, record, explain and test.
WhaleWatcher does more than flash a live alert. It records qualifying signals so members can study what happened afterward.
Large-print activity with transparent buy/sell direction proxies, notional size, source, score, tier, and methodology.
Daily and monthly stacks, raw signal ledger, Market Tide, Whale of the Day, heating-up names, and recorded whale price levels.
Track what happened after recorded signals at 5 minutes, 30 minutes, 1 hour, 24 hours, 5 days and 30 days—with sample sizes shown.
Replay a recorded trading day or investigate one ticker using whale history, historical trend context and SEC/insider data.
Save tickers, set Whale Score thresholds, enable browser notifications, and ask WhaleWatcher questions grounded in the recorded dataset.
Run live signals against fake cash with persistent positions, P/L, a full ledger, event history, reset controls and clear-history controls.
Recent insider/SEC context plus long-window trend and seasonality research to put a whale signal in context.
Automatic monitoring keeps market feeds, signal recording, billing, and maintenance healthy behind the scenes without cluttering the member experience.
Know what happened. Know why it matters. Measure what came next.
WhaleWatcher is built to give serious market participants more than alerts. Every important signal is designed to carry evidence, context, limitations and follow-through so members can judge the intelligence instead of blindly trusting a score.
See the evidence behind a signal: notional size, repeat activity, directional proxy, confirmation layers, insider context and historical behavior.
Time-stamped signals create an auditable trail. Review what WhaleWatcher knew at detection time instead of judging a call with hindsight.
Measure follow-through at multiple horizons with sample sizes so members can distinguish repeatable patterns from attractive noise.
Replay signals, inspect SEC and insider context, study historical analogues and paper-test ideas before considering any real-money decision.
