⚠️ **Trading warning / Avertissement trading** : informational only, not investment advice. Indicators summarize the past; a bullish signal is not a forecast and fails regularly. Curated by Skill Harbor: a chartist's indicator panel computed for you, for one ticker or a comma-separated list. It calculates RSI, MACD, Bollinger Bands, SMA and EMA sets, ATR, and ADX over your chosen period with the pandas-ta library, reports the most recent MACD and EMA 9/21 crossovers and how many bars ago they happened, bundles volatility and Sharpe as risk metrics, and can attach upcoming earnings dates with EPS history. A companion script in the same skill builds a price correlation matrix across several symbols, the diversification check that shows whether your positions actually move independently or are secretly the same trade. Outputs come back as structured JSON with plain interpretation levels (RSI above 70 overbought, below 30 oversold, ADX above 25 a strong trend). It runs as Python scripts (scripts/technicals.py and scripts/correlation.py) from the staskh/trading_skills repo. From the staskh/trading_skills repository (MIT). Honest caveats: indicators generate heuristics, not predictions, and every signal here fires false positives, especially in sideways markets; Yahoo Finance data is unofficial and can be delayed, or adjusted differently than your broker's feed. Skill Harbor never reviews the code, review it yourself before use.

Install
Copy the install package below, then paste it into MuseThe install prompt below already includes the vetting steps: your agent follows the community checklist before installing anything with executable code. Want more?
Use "Technical Analysis" with your Muse. Prerequisites: clone the repo once (git clone https://github.com/staskh/trading_skills) and keep the folder handy; the skills live in .claude/skills/ and the scripts run from the repo with uv (uv run python), or with plain python if uv is not installed. This skill needs numpy, pandas, pandas-ta, and yfinance, installed through the repo project. No API key and no brokerage account are required; price data comes from Yahoo Finance via the free yfinance library (unofficial, possibly delayed). 1. Open the skill: https://github.com/staskh/trading_skills/blob/main/.claude/skills/technical-analysis/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Run the technicals for AAPL, MSFT, GOOGL over 3 months: RSI, MACD, Bollinger Bands, EMA and SMA, any recent MACD or EMA crossovers, and the correlation matrix between the three." 3. Weight a crossover by its age: one that fired 0 to 5 bars ago is a fresh event, one from 40 bars ago is history the price has already answered. Tip: the MACD usually turns first and the EMA 9/21 confirms a few bars later; an unconfirmed crossover is the one that fails most often. Safety: a skill is plain-text instructions; it runs nothing by itself. This is informational only, not investment advice.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
