Big moves, a closer look

Signals come from changes in the scanner's largest recorded positions, not a complete trade tape. Size is the change in shares valued at the observed price; buys and sells can be approximate.

Whales move $25K or more. New-wallet activity starts at $5K. The radar also looks for accumulation, thin-market impact, high-scoring traders changing sides and groups entering together.

Positions are usually re-read every 15 minutes; mention markets every 2 minutes. This feed refreshes every minute. Crypto up/down markets and moves at 98¢ or more or 2¢ or less are excluded.
