MACD — Moving Average Convergence Divergence

Calculate MACD from price data. Compute EMA, MACD line, signal line, and histogram from a CSV or inline price series.

Requirements

bash 4+
python3 (standard library only)

Commands

calculate

Calculate MACD from a comma-separated price series.

bash scripts/script.sh calculate "170.5,171.2,172.8,171.0,173.5,174.2,175.0,174.8,176.1,175.5,177.2,178.0,176.5,177.8,179.0,178.5,180.2,179.8,181.0,180.5,182.3,181.8,183.0,182.5,184.0,183.5"

calculate-file

Usage Guidance

This skill appears to do only local MACD calculations using your provided price series or a CSV file. Before running: ensure you have python3 and bash available; only pass files you intend the tool to read (it will open any path you give it); if you plan to run untrusted skills, consider running them in a sandbox. Also validate numeric results (indexing/alignment logic in the script is a bit intricate) before using outputs for live trading decisions — this review addresses coherence, not financial correctness.

Capability Analysis

Type: OpenClaw Skill Name: macd Version: 2.0.4 The skill contains a command injection vulnerability in `scripts/script.sh` within the `cmd_calculate_file` function. The script interpolates the `$file` variable directly into an unquoted Python heredoc (`python3 << PYEOF`), which allows for arbitrary Python code execution if a maliciously crafted filename is provided. While the overall functionality appears to be a legitimate MACD calculator for trading, this lack of input sanitization in a shell script is a high-risk vulnerability.

Capability Assessment

✓ Purpose & Capability

Name/description match the included code and instructions. The skill only requires bash and python3 and exposes commands to calculate MACD from an inline series or a CSV file, interpret values, and display trading guidance — all consistent with a MACD calculator.

✓ Instruction Scope

SKILL.md instructs the agent to run the provided scripts/script.sh commands. The script only reads user-supplied input (inline price list or a file path), computes values locally, and prints results. It does not reach out to external endpoints or read environment variables beyond those it sets to pass data to Python. Note: calculate-file reads whatever file path the user supplies (expected for this feature).

✓ Install Mechanism

No install spec is provided and the skill is instruction/script-only. Nothing is downloaded or written to disk by an installer — the lowest-risk model for install behavior.

✓ Credentials

The skill declares no required environment variables, no credentials, and no config paths. The script uses temporary environment variables to pass parameters to the embedded Python invocations only, which is proportional to its function.

✓ Persistence & Privilege

always is false and the skill does not request persistent or elevated agent/system privileges. It does not modify other skills or alter system configuration.

How to Use

Make sure OpenClaw is installed (local or Docker)
Run the install command in chat: /install macd
After installation, invoke the skill by name or use /macd
Provide required inputs per the skill's parameter spec and get structured output
