+# Trading Scripts: Market Data Fetcher
+
+Historical market data pipeline for AI analysis. Fetches stocks/futures/crypto, computes stats/charts, exports for uncensored LLMs.
+
+## 🚀 Quick Start
+
+```bash
+# Install deps (one-time)
+pip install yfinance pandas matplotlib seaborn plotly kaleido pyarrow
+
+# Basic 1Y report
+python market_data.py --period 1y --groups stocks futures crypto --output ./report-1y
+
+# Live daily movers
+python market_data.py --period 1d --groups meme --output ./today-movers
+```
+
+## 📊 Features
+
+- **1Y+ History** (auto-adjusts interval: 1d for long periods)
+- **Futures-safe** (flattens MultiIndex for ES=F etc., drops NaN gaps)
+- **Stats:** Total/annual returns, volatility, max drawdown, volume
+- **Exports:** CSV/Parquet/JSON + PNG charts + interactive HTML
+- **Groups:** `stocks` (AAPL/TSLA), `futures` (ES=F/NQ=F), `crypto` (BTC-USD), `meme` (GME)
+
+## Usage
+
+```bash
+python market_data.py [OPTIONS]
+
+Options:
+  --tickers AAPL,TSLA,ES=F     Comma-separated (default: AAPL,TSLA,ES=F,BTC-USD)
+  --period 1y                  1mo|3mo|6mo|1y|2y|5y|10y|ytd|max (default: 1y)
+  --interval 1d                1m|5m|1h|1d|1wk (auto-adjusts)
+  --groups stocks futures      Add predefined groups
+  --output ./reports           Output dir (default: ./market-historical)
+```
+
+## Examples
+
+**Retail Biz Demo:**
+```bash
+python market_data.py --period 1y --tickers AAPL,TSLA --output retail-stocks
+# Feed report JSON to uncensored bot: "Analyze TSLA for landscaping firm cashflow"
+```
+
+**Daily Alerts (Cron):**
+```bash
+# Save daily to /opt/data/market-daily
+0 9 * * 1-5 python /opt/gcloud-lab/trading-scripts/market_data.py --period 1d --output /opt/data/market-daily/today
+```
+
+**Meme Stocks Live:**
+```bash
+python market_data.py --period 5d --groups meme --interval 1h --output meme-watch
+```
+

+
+## AI Integration (OpenClaw/Uncensored Bots)
+
+```python
+import json
+with open('report/historical_report.json') as f:
+    data = json.load(f)
+
+prompt = f"Analyze these 1Y stats for retail biz: {json.dumps(data['stats'])}"
+# POST to vLLM: http://openclaw-brain-service:8000/v1/chat/completions
+```
+
+## Troubleshooting
+
+- **No data:** Check market hours (futures/crypto 24/7)
+- **MultiIndex error:** Auto-handled (memory quirk fixed)
+- **Large files:** Use `--period 1mo` or Parquet
+- **Deps:** `pyarrow` for Parquet read/write
+
+**For clients:** "Uncensored AI stock insights — privacy-first, no filters."
