One chart starts the question. Historical examples help us examine it. We investigate the comparisons and their differences to learn what makes market memory useful for people and AI agents.

See the matches, inspect the differences, and understand what the evidence can tell us.
We matched IONQ's final ten bars to 50 historical moments, then inspected the preceding hour. Elapsed time, missing bars, and the earlier move changed the comparison.
Both charts decline late, but IONQ enters that interval below its hour-start price while PENN enters above it. A follow-up using the original 50 comparisons.
Follow-up on the original sample; outcomes not tested
A case can introduce a setup, examine a misleading lookalike, investigate the event behind a move, or report a completed test. Each entry states what was observed and what remains untested.
Similarity gives us examples to investigate. Claims about an edge require a separate test with rules fixed before the confirmation data are inspected.
