harmonic

harmonic is a skill for Claude Code, Codex from skloxo/TideTrading. It costs 49 tokens per session (370 once invoked), scanned A, a copy of harmonic, MIT.

A trading-signal method that finds five-point XABCD chart patterns using Fibonacci ratios, mathematical relationships often used to compare price swings. It uses the area around point D, called the potential reversal zone, to identify possible turns.

In plain words
What is it for?
Use it to detect Gartley, Bat, Butterfly, and Crab patterns and produce bullish or bearish signals in the potential reversal zone.
Why use it?
It gives traders specific price relationships to check when looking for a potential market reversal.

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

harmonic 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 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (example_signal_engine.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.

Origin

What it actually says

Harmonic Patterns

Purpose

The Fibonacci geometry school uses precise ratio relationships to identify price patterns:

Pattern B-Point Retracement D-Point Retracement Direction
Gartley 0.618 XA 0.786 XA Reversal
Bat 0.382-0.5 XA 0.886 XA Reversal
Butterfly 0.786 XA 1.27 XA Reversal
Crab 0.382-0.618 XA 1.618 XA Reversal

Core Concepts

  • XABCD five-point pattern: a price structure defined by precise Fibonacci ratios
  • PRZ (Potential Reversal Zone): the convergence area around point D, where reversal probability is high
  • Bullish pattern (point D at the bottom) → buy signal
  • Bearish pattern (point D at the top) → sell signal

Dependencies

pip install "vibe-trading-ai[harmonic]"

pyharmonics is optional. If the extra is not installed, the example signal engine falls back to the bundled detector.

Parameters

Parameter Default Description
is_stock False Whether the instrument is a stock (affects analysis parameters)

Signal Convention

  • 1 = long, -1 = short, 0 = stand aside
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
