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 \ --sector "T

How do I install it?
Run `npx skills add BaggaT236/AI-Trading-Skills --skill downtrend-duration-analyzer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From BaggaT236/AI-Trading-Skills, a repository with 118 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
