Whale Activity Scanner
WhaleWatcher surfaces unusually large market activity and stores a time-stamped record so traders can evaluate whether a signal actually mattered after the fact.
Open WhaleWatcherWhy history matters
A scanner is more useful when you can go back and inspect what it showed before a move. WhaleWatcher is designed to preserve signal history, not just flash a momentary alert.
What you can study
- Large-trade activity and size
- Up-tick/down-tick directional proxy context
- Signal timing and later price behavior
- Repeat activity in the same symbol
- Paper-simulation outcomes saved to your account
Data caveat
Large-trade direction is an inference from market behavior, not proof of who bought or sold. WhaleWatcher labels these limitations rather than presenting inferred flow as certainty.
