Claude Trading Skills is a collection of Claude Code workflows for individual investors who want structured market analysis, charting, economic-calendar review, screening, trade planning, journaling, and risk management. It is designed for people using long-term investing, ETFs, dividend stocks, and disciplined swing trading, and the catalogue entries package these workflows as skills, agents, commands, settings, and instructions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00064 | $0.03470 |
| Opus 5.5 | $0.00026 | $0.01388 |
| Sonnet 5.5 | $0.00013 | $0.00694 |
| Haiku 4.5 | $0.00006 | $0.00347 |
Grade A, and why
institutional-flow-tracker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 15d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Institutional Flow Tracker
Overview
This skill tracks institutional investor activity through 13F SEC filings to identify "smart money" flows into and out of stocks. By analyzing quarterly changes in institutional ownership, you can discover stocks that sophisticated investors are accumulating before major price moves, or identify potential risks when institutions are reducing positions.
Key Insight: Institutional investors (hedge funds, pension funds, mutual funds) manage trillions of dollars and conduct extensive research. Their collective buying/selling patterns often precede significant price movements by 1-3 quarters.
Prerequisites
- FMP API Key: Set
FMP_API_KEYenvironment variable or pass--api-keyto scripts - Python 3.9+: Required for running analysis scripts
- Dependencies:
pip install requests(scripts handle missing dependencies gracefully)
When to Use This Skill
Use this skill when:
- Validating investment ideas (checking if smart money agrees with your thesis)
- Discovering new opportunities (finding stocks institutions are accumulating)
- Risk assessment (identifying stocks institutions are exiting)
- Portfolio monitoring (tracking institutional support for your holdings)
- Following specific investors (tracking Warren Buffett, Cathie Wood, etc.)
- Sector rotation analysis (identifying where institutions are rotating capital)
Do NOT use when:
- Seeking real-time intraday signals (13F data has 45-day reporting lag)
- Analyzing micro-cap stocks (<$100M market cap with limited institutional interest)
- Looking for short-term trading signals (<3 months horizon)
Data Sources & Requirements
Required: FMP API Key
This skill uses Financial Modeling Prep (FMP) API to access 13F filing data:
Setup:
# Set environment variable (preferred)
export FMP_API_KEY=your_key_here
# Or provide when running scripts
python3 scripts/track_institutional_flow.py --api-key YOUR_KEY
FMP transport (rate limiting, single 429 retry, apikey header auth so the key never appears in a URL) is owned by the vendored generated `scripts/fmp_client.py` (Issue #495).

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
