Market Breadth Analyzer

Pulls TraderMonty's public CSV data from GitHub Pages and calculates a 0-100 composite health score across six weighted components: breadth level and trend (25%), moving average crossovers (20%), peak/trough cycles (20%), bearish signals (15%), historical percentiles (10%), and S&P 500 divergence (10%). No API keys needed. The script auto-redistributes weights if any component lacks data, tracks score history across runs, and maps results to equity exposure recommendations (80+ means go full position, sub-20 means raise cash). Useful when you want a quantitative answer to "is this rally broad-based?" instead of eyeballing charts. Outputs both JSON and markdown reports with trend analysis.

Purpose

Quantify market breadth health using a data-driven 6-component scoring system (0-100). Uses TraderMonty's publicly available CSV data to measure how broadly the market is participating in a rally or decline.

Score direction: 100 = Maximum health (broad participation), 0 = Critical weakness.

No API key required - uses freely available CSV data from GitHub Pages.
