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

candlestick 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 9d 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.

What it actually says

Candlestick Pattern Recognition

Purpose

Identifies 15 classic candlestick patterns and generates trading signals:

Single-Candle Patterns (5)

Pattern Signal Description
Hammer Bullish Long lower shadow with a small body at the top
Inverted Hammer Bullish Long upper shadow with a small body at the bottom
Shooting Star Bearish Long upper shadow with a small body at the bottom (appears after an uptrend)
Doji Neutral Open and close are nearly equal
Spinning Top Neutral Small body with roughly equal upper and lower shadows

Double-Candle Patterns (5)

Pattern Signal
Bullish Engulfing Bullish
Bearish Engulfing Bearish
Bullish Harami Bullish
Bearish Harami Bearish
Piercing Line Bullish
Dark Cloud Cover Bearish

Triple-Candle Patterns (4)

Pattern Signal
Morning Star Bullish
Evening Star Bearish
Three White Soldiers Bullish
Three Black Crows Bearish

Signal Logic

Bullish patterns score +1, bearish patterns score -1. Go long when the total score is > 0, go short when it is < 0, and stand aside when it equals 0.

Parameters

Parameter Default Description
body_pct 0.1 Threshold for body-to-range ratio in a doji
shadow_ratio 2.0 Ratio of shadow length to body length

Dependencies

pip install pandas numpy requests

Signal Convention

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

What ships with it

1 file 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.
