Prerequisites
Install required dependencies:
set -euo pipefail pip install yfinance pandas numpy

Instructions
Quick signal scan across multiple assets:
python ${CLAUDE_SKILL_DIR}/scripts/scanner.py --watchlist crypto_top10 --period 6m
Output shows signal type (STRONG_BUY/BUY/NEUTRAL/SELL/STRONG_SELL) and confidence per asset.
Detailed signal analysis for a specific symbol:
python ${CLAUDE_SKILL_DIR}/scripts/scanner.py --symbols BTC-USD --detail
Shows each indicator's individual signal, value, and reasoning.
Filter and rank the best opportunities:
Only buy signals with 70%+ confidence
python ${CLAUDE_SKILL_DIR}/scripts/scanner.py --filter buy --min-confidence 70 --rank confidence
Save results to JSON
python ${CLAUDE_SKILL_DIR}/scripts/scanner.py --output signals.json
Use predefined watchlists:
python ${CLAUDE_SKILL_DIR}/scripts/scanner.py --list-watchlists python ${CLAUDE_SKILL_DIR}/scripts/scanner.py --watchlist crypto_defi
Available: crypto_top10 , crypto_defi , crypto_layer2 , stocks_tech , etfs_major
Output
The scanner produces a summary table with symbol, signal type, confidence %, price, and stop loss for each asset scanned. Detailed mode adds per-indicator breakdowns with risk management levels (stop loss, take profit, risk/reward ratio).
Signal types: STRONG_BUY (+2), BUY (+1), NEUTRAL (0), SELL (-1), STRONG_SELL (-2)
Confidence ranges: 70-100% high conviction | 50-70% moderate | 30-50% weak | 0-30% avoid
