What counts as a signal on this page?
This view collects the scanner's big move up, big move down signals. Each row states the engine's one-line read — what was flagged and why.
How often does this update?
The scanner runs after every US close; this page is rebuilt every market morning from that scan and always shows the date it was built from. The daily archive keeps every previous board day.
