technical-basic

technical-basic is a skill for Claude Code, Codex from HKUDS/Vibe-Trading. It costs 48 tokens per session (508 once invoked), scanned A, original, MIT.

A Python data-analysis component that combines trend, price-reversal, and trading-volume indicators from OHLCV data, meaning open, high, low, close, and volume records. It produces a combined long, short, or stand-aside signal.

In plain words
What is it for?
Use it to calculate EMA, ADX, Bollinger Bands, RSI, OBV, and volume ratios with pandas for market-data analysis.
Why use it?
It brings several common market measurements into one consistent signal instead of requiring separate checks. Mixed indicators result in a stand-aside signal.

About the project

Vibe-Trading is a personal trading agent that gives an AI system tools for market analysis, algorithmic trading, backtesting, and related workflows. It is for users who want an agent to research and evaluate trading strategies or manage simulated and other trading activities. The catalogue contains skills that expose these trading capabilities to compatible agents.

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

technical-basic 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 2d 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

Core Technical Indicator Collection

Purpose

Combines three classic Western technical analysis approaches into one composite signal engine:

Dimension Indicators Purpose
Trend EMA(12/26) + ADX(14) Determine direction and trend strength
Mean reversion Bollinger Bands(20,2) + RSI(14) Detect overbought and oversold conditions
Volume-price OBV + volume ratio Confirm volume participation

Signal Logic

Three-dimensional voting mechanism:

  • Long: trend is bullish + RSI is not overbought + OBV is rising
  • Short: trend is bearish + RSI is not oversold + OBV is falling
  • Stand aside: mixed signals

Key Implementation Details

  • RSI and ADX use Wilder EWM (ewm(alpha=1/period)), not a rolling mean
  • Full ADX chain: +DM/-DM → TR → +DI/-DI → DX → ADX
  • OBV = (volume * sign(close.diff())).cumsum()

Parameters

All parameters have default values and can be overridden at instantiation time:

Parameter Default Description
ema_fast 12 Fast EMA period
ema_slow 26 Slow EMA period
adx_period 14 ADX calculation period
adx_threshold 25.0 ADX trend-strength threshold
bb_window 20 Bollinger Band window
bb_std 2.0 Bollinger Band standard deviation multiplier
rsi_period 14 RSI period
rsi_oversold 30 RSI oversold threshold
rsi_overbought 70 RSI overbought threshold
vol_ma_period 20 Volume moving-average period
obv_ma_period 20 OBV moving-average period

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.

technical-basic is a skill published in the GitHub repository HKUDS/Vibe-Trading (32,590 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 508 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
