Breadth Chart Analyst

If you're tracking market health through breadth indicators, this skill analyzes two specific charts: the S&P 500 Breadth Index (200-day MA based) for medium-term strategic positioning and the US Stock Market Uptrend Stock Ratio for short-term tactical timing. It fetches CSV data directly from public GitHub sources, so you don't need chart images or API keys, though images add visual context. The analysis applies backtested strategies with clear thresholds: buy when the 8MA reverses from troughs below 23%, sell when the 200MA peaks near 73%, and use color shifts in the uptrend ratio for swing trades. Output is markdown reports with signal identification, scenario probabilities, and positioning recommendations. All analysis happens in English.
