Short answer

How can I use AI to analyze historical price action?

Your agent uses the Polygon.io MCP to fetch historical OHLCV aggregates for any ticker. It then processes these bars to check for specific price movements or technical setups. You get a clear breakdown of the data and the patterns found.
