What it does
Market Breadth Analyzer is an agent skill from tradermonty/claude-trading-skills. Quantifies market breadth health using TraderMonty's public CSV data. Generates a 0-100 composite score across 6 components (100 = healthy). No API key required. Use when user asks about market breadth, participation rate, advance-decline health, whether the rally is broad-based, or general market health assessment.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 29 other files, including scripts and reference files (for example `references/breadth_analysis_methodology.md`, `scripts/calculators/__init__.py` and `scripts/calculators/bearish_signal_calculator.py`).
It sits in Documents & Office, covering CSV and tabular files. The repository describes itself as: Claude Code skills for equity investors and traders — market analysis, technical charting, economic calendars, screeners, and trading strategy development. The licence is MIT.
When your agent uses it
- User asks about market breadth
- Participation rate
- Advance-decline health
- Whether the rally is broad-based
Example prompts
- “Use the market-breadth-analyzer skill to quantify market breadth health using TraderMonty's public CSV data”

Workflow steps
2 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit eab8d5c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 14 files in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
tradermonty.github.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Market Breadth Analyzer loads about 1.6k tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 85 tokens; SKILL.md has 645 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- description
- Quantifies market breadth health using TraderMonty's public CSV data. Generates a 0-100 composite score across 6 components (100 = healthy). No API key required. Use when user asks about market breadth, participation rate, advance-decline health, whether the rally is broad-based, or general market health assessment.
Market Breadth Analyzer Skill
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.
When to Use This Skill
English:
- User asks "Is the market rally broad-based?" or "How healthy is market breadth?"
- User wants to assess market participation rate
- User asks about advance-decline indicators or breadth thrust
- User wants to know if the market is narrowing (fewer stocks participating)
- User asks about equity exposure levels based on breadth conditions
Japanese:
- 「マーケットブレッドスはどうですか？」「市場の参加率は？」
- 「上昇は広がっている？」「一部の銘柄だけの上昇？」
- ブレッドス指標に基づくエクスポージャー判断
- 市場の健康度をデータで確認したい
Prerequisites
- Python 3.9+ with
requestslibrary (for fetching CSV data) - Internet access to reach GitHub Pages URLs
- No API keys required - uses freely available public CSV data
Difference from Breadth Chart Analyst
| Aspect | Market Breadth Analyzer | Breadth Chart Analyst |
|---|---|---|
| Data Source | CSV (automated) | Chart images (manual) |
| API Required | None | None |
| Output | Quantitative 0-100 score | Qualitative chart analysis |
| Components | 6 scored dimensions | Visual pattern recognition |
| Repeatability | Fully reproducible | Analyst-dependent |
Execution Workflow
Phase 1: Execute Python Script
Run the analysis script. If using a nested or date-stamped --output-dir in cron runs, create it first; the history writer expects the directory to already exist.
mkdir -p reports/<routine-or-date>
python3 skills/market-breadth-analyzer/scripts/market_breadth_analyzer.py \
--detail-url "https://tradermonty.github.io/market-breadth-analysis/market_breadth_data.csv" \
--summary-url "https://tradermonty.github.io/market-breadth-analysis/market_breadth_summary.csv" \
--output-dir reports/<routine-or-date>For a simple ad-hoc run, omit --output-dir or use an existing directory. In scheduled cron runs from the repository root, prefer a repo-relative output directory such as reports/after-close-YYYY-MM-DD rather than an absolute path. If an absolute nested --output-dir unexpectedly fails at the history-writing step despite the directory existing, rerun once with the equivalent repo-relative path before treating the breadth analysis as unavailable.
The script will:
- Fetch detail CSV (~2,500 rows, 2016-present) and summary CSV (8 metrics)
- Validate data freshness (warn if > 5 days old)
- Calculate all 6 component scores (with automatic weight redistribution if any component lacks data)
- Generate composite score with zone classification
- Track score history and compute trend (improving/deteriorating/stable)
- Output JSON and Markdown reports
Phase 2: Present Results
Present the generated Markdown report to the user, highlighting:
- Composite score and health zone
- Strongest and weakest components
- Recommended equity exposure level
- Key breadth levels to watch
- Any data freshness warnings

6-Component Scoring System
| # | Component | Weight | Key Signal |
|---|---|---|---|
| 1 | Breadth Level & Trend | 25% | Current 8MA level + 200MA trend direction + 8MA direction modifier |
| 2 | 8MA vs 200MA Crossover | 20% | Momentum via MA gap and direction |
| 3 | Peak/Trough Cycle | 20% | Position in breadth cycle |
| 4 | Bearish Signal | 15% | Backtested bearish signal flag |
| 5 | Historical Percentile | 10% | Current vs full history distribution |
| 6 | S&P 500 Divergence | 10% | Multi-window (20d + 60d) price vs breadth divergence |
Weight Redistribution: If any component lacks sufficient data (e.g., no peak/trough markers detected), it is excluded and its weight is proportionally redistributed among the remaining components. The report shows both original and effective weights.
Score History: Composite scores are persisted across runs (keyed by data date). The report includes a trend summary (improving/deteriorating/stable) when multiple observations are available.
Health Zone Mapping (100 = Healthy)
| Score | Zone | Equity Exposure | Action |
|---|---|---|---|
| 80-100 | Strong | 90-100% | Full position, growth/momentum favored |
| 60-79 | Healthy | 75-90% | Normal operations |
| 40-59 | Neutral | 60-75% | Selective positioning, tighten stops |
| 20-39 | Weakening | 40-60% | Profit-taking, raise cash |
| 0-19 | Critical | 25-40% | Capital preservation, watch for trough |
Data Sources
