Test_Ros_MCP_Indicator by Claude + 2 drawings

This is a test Indicator created by Claude AI. MCP server connected to DEV was used.

 There were several errors in the code, like.

I need to fix the return type annotation for _collect_pivots. Since it returns a list of lists, I need to specify the exact type. In Indie, I need to use list[list[float]] to specify a list of lists of floats.

Let me also fix the _calculate_trend_line method that returns two floats - I should return a tuple, not a list.
