stockbee-20pct-study

stockbee-20pct-study is a skill for Claude Code, Codex from BaggaT236/AI-Trading-Skills. It costs 87 tokens per session (1,504 once invoked), scanned A, a copy of stockbee-20pct-study, MIT.

A research workflow for studying US stocks that rose or fell by 20% or more during a chosen period. It records the likely news cause, chart conditions, and what happened afterward.

In plain words
What is it for?
Use it to scan recent or historical 20% stock movers, classify their catalysts and setups, track later results, and build a reference book of recurring market patterns.
Why use it?
It turns large daily price moves into consistent records, making it easier to compare winners, failures, reversals, and recurring patterns over time. It is for research, not trading instructions or order placement.

Token cost

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.

Security

Grade A, and why

stockbee-20pct-study 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 12d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/run_20pct_study.py, scripts/tests/test_cli_outputs.py, scripts/tests/test_cohort_summary.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

Stockbee 20% Study

Build a daily event study of US equities that moved +20% or -20% over a defined window. Convert large movers into structured study records, classify the catalyst and chart context, update forward outcomes, and summarize recurring patterns for research.

This skill is a research, model-book, and setup-fluency workflow. It does not generate buy/sell signals, place orders, or output broker execution instructions.

When to Use

  • User wants to run a Stockbee-style daily 20% mover study
  • User asks which stocks moved +20% or -20% today, this week, or over a configurable lookback window
  • User wants to backfill historical 20% movers and study what happened next
  • User wants to identify continuation, reversal, exhaustion, or theme-cluster patterns
  • User wants to build a model book of explosive winners, major failures, and failed low-quality pops
  • User wants edge hints for downstream strategy research rather than immediate trade signals

Prerequisites

  • Python 3.9+
  • FMP API key for live US universe scans, or offline OHLCV JSON via --prices-json
  • Optional structured news/catalyst JSON for higher-quality catalyst classification
  • Recommended market regime artifact from market-regime-daily
  • Recommended local state path: state/stockbee/20pct_study_events.jsonl

Workflow

Step 1: Scan for 20% Movers

Run after the US market close, or against the latest complete daily bar in an offline OHLCV file.

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.
