At a glance

Builds a composite trading signal from three groups of classic indicators (trend, mean reversion, volume) voting long, short or flat, in plain pandas for OHLCV data.

  • Backtesting a trend plus mean-reversion strategy on OHLCV data
  • SKILL.md covers Purpose, Signal Logic, Key Implementation Details and Parameters, plus 2 more sections
  • Runs Python scripts from its folder; calls pip
  • Combining EMA, ADX, RSI and OBV into a single long-short signal

What it does

This skill combines three groups of classic technical indicators into one signal engine: trend from fast and slow EMAs plus ADX, mean reversion from Bollinger Bands plus RSI, and volume confirmation from OBV and a volume ratio. A three-way vote sets the position. It goes long when the trend is up, RSI is not overbought and OBV is rising, short for the mirror image, and flat when the signals disagree.

Everything is plain pandas and works on any OHLCV data. RSI and ADX use Wilder exponential smoothing rather than a rolling mean, and OBV is a cumulative sum of signed volume. All parameters have defaults, such as EMA periods of 12 and 26, ADX and RSI periods of 14, a Bollinger window of 20 and RSI bounds of 30 and 70, and each can be overridden when the engine is created. An example signal engine is included, and signals are 1, -1 or 0.

When your agent uses it

  • Backtesting a trend plus mean-reversion strategy on OHLCV data
  • Combining EMA, ADX, RSI and OBV into a single long-short signal
  • Tuning indicator periods and thresholds for a rule-based signal engine

Example prompts

  • “Generate long and short signals from EMA, ADX, RSI and OBV for data/btc_daily.csv.”
  • “Run the technical-basic strategy on my OHLCV file and widen the RSI oversold and overbought thresholds.”
  • “Explain why the engine uses Wilder smoothing for RSI and ADX instead of a rolling mean.”

Requirements

  • Python with `pandas`, `numpy` and `requests`

What it can do on your machine

Read from SKILL.md and the folder at commit 7f6908b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Core Technical Indicator Signals loads about 492 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 183 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~492

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Core technical indicator collection (trend EMA/ADX + mean-reversion BB/RSI + volume-price OBV/volume ratio), generates a composite signal via three-dimensional voting. Pure pandas implementation for any OHLCV data.

Core Technical Indicator Collection

Purpose

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

DimensionIndicatorsPurpose
TrendEMA(12/26) + ADX(14)Determine direction and trend strength
Mean reversionBollinger Bands(20,2) + RSI(14)Detect overbought and oversold conditions
Volume-priceOBV + volume ratioConfirm 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:

ParameterDefaultDescription
ema_fast12Fast EMA period
ema_slow26Slow EMA period
adx_period14ADX calculation period
adx_threshold25.0ADX trend-strength threshold
bb_window20Bollinger Band window
bb_std2.0Bollinger Band standard deviation multiplier
rsi_period14RSI period
rsi_oversold30RSI oversold threshold
rsi_overbought70RSI overbought threshold
vol_ma_period20Volume moving-average period
obv_ma_period20OBV moving-average period

Dependencies

bash
pip install pandas numpy requests

Signal Convention

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