Example Conversation

User: What does NVDA's chart look like right now?

Claude (using Chart Library): NVDA's current pattern matches 10 historical setups. The closest is AAPL from May 2016 (93% similarity). Of the 10 matches, 8 went up over 5 days with an average gain of +3.0%. The current market regime resembles the post-SVB period of early 2023, which historically resolved bullishly.
