Chart Library — what happened after stocks like this

# Chart Library — Market memory for AI > Historical market context for AI agents. Open research for AI and humans. Retrieve historical market states, comparable situations and what followed. Use the research to inspect the comparisons, question similarities and understand the limits. This is market evidence to reason with, not stored agent conversations.
