breadth-chart-analyst

breadth-chart-analyst is a skill for Claude Code, Codex from nicepkg/ai-workflow. It costs 93 tokens per session (5,684 once invoked), scanned A, a copy of breadth-chart-analyst, MIT.

A market-breadth chart analyst for two US stock-market indicators: the share of S&P 500 stocks above their 200-day average and the share in an uptrend. Market breadth shows how widely a market move is supported by individual stocks.

In plain words
What is it for?
Assessing market strength, identifying entry or exit signals, and developing positioning guidance from supplied breadth-chart images.
Why use it?
It turns chart readings into medium-term and short-term views of market health. It also applies defined thresholds and historical strategy results to reduce subjective interpretation.

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

breadth-chart-analyst 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 yesterday.

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.

Breadth Chart Analyst

Overview

This skill enables specialized analysis of two complementary market breadth charts that provide strategic (medium to long-term) and tactical (short-term) market perspectives. Analyze breadth chart images to assess market health, identify trading signals based on backtested strategies, and develop positioning recommendations. All thinking and output are conducted exclusively in English.

Core Principles

  1. Dual-Timeframe Analysis: Combine strategic (Chart 1: 200MA Breadth) and tactical (Chart 2: Uptrend Ratio) perspectives
  2. Backtested Strategy Focus: Apply proven systematic strategies based on historical patterns
  3. Objective Signal Identification: Focus on clearly defined thresholds, transitions, and markers
  4. English Communication: Conduct all analysis and generate all reports in English
  5. Actionable Recommendations: Provide specific positioning guidance for different investor types

Chart Types and Purposes

Chart 1: S&P 500 Breadth Index (200-Day MA Based)

Purpose: Medium to long-term strategic market positioning

Key Elements:

  • 8-Day MA (Orange Line): Short-term breadth trend, primary entry signal generator
  • 200-Day MA (Green Line): Long-term breadth trend, primary exit signal generator
  • Red Dashed Line (73%): Average peak level - market overheating threshold
  • Blue Dashed Line (23%): Average 8MA trough level - extreme oversold, excellent buying opportunity
  • Triangles:
    • Purple ▼ = 8MA troughs (buy signal when reverses)
    • Blue ▼ = 200MA troughs (major cycle lows)
    • Red ▲ = 200MA peaks (sell signal)
  • Pink Background: Downtrend periods

Backtested Strategy:

  • BUY: When 8MA reverses from a trough (especially below 23%)
  • SELL: When 200MA forms a peak (typically near/above 73%)
  • Result: Historically high performance, avoids bear markets

Chart 2: US Stock Market - Uptrend Stock Ratio

Purpose: Short-term tactical timing and swing trading

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.
