Analyze historical downtrend durations and generate interactive HTML histograms showing typical correction lengths by sector and market cap.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Downtrend Duration Analyzer ## Overview Analyze historical price data to identify downtrend periods (peak-to-trough) and build statistical distributions of correction durations. Generate interactive HTML visualizations with histograms segmented by sector and market cap to help traders understand typical recovery timeframes and set realistic expectations for mean reversion strategies. ## When to Use - Trader asks about typical correction lengths for a sector or market cap tier - User wants to understand historical drawdown recovery times - Building mean reversion or pullback strategies that need realistic holding period estimates - Comparing correction behavior across different market segments - Setting stop-loss timeouts or position holding period limits ## Prerequisites - Python 3.9+ - FMP API key (set `FMP_API_KEY` environment variable or use `--api-key`) - Required packages: `requests`, `pandas`, `numpy` (standard data analysis stack) ## Workflow ### Step 1: Fetch Historical Price Data Run the analysis script to fetch OHLC data for a universe of stocks and identify downtrend periods. ```bash python3 skills/downtrend-duration-analyzer/scripts/analyze_downtrends.py \ …

How to install
mdr add tradermonty/claude-trading-skills/downtrend-duration-analyzer@sha256:9d9e0610ad571ad6The line at the top of this page pins the label git:20260330.3866e7d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
