charting
Generate TradingView-style candlestick charts with technical indicators for price visualization and analysis.
- Supports candlestick charts with optional overlays (EMA, SMA, Bollinger Bands) and subplots (RSI, MACD) for crypto via CoinGecko and stocks/forex/commodities via Twelve Data
- Auto-selects optimal data intervals (hourly for ≤31 days, daily for longer ranges) to balance visual quality and data volume
- Chart scripts run standalone in the workspace using
requestsdirectly; templates handle data fetching, retry logic, and proxy auto-configuration - Includes four template scripts for simple price action, indicator analysis, stock/forex charts, and asset comparisons; customize config section and run with

⚠️ CRITICAL: DO NOT CALL DATA TOOLS
NEVER call price_chart, get_coin_ohlc_range_by_id, twelvedata_time_series, or ANY market data tools when creating charts. Chart scripts fetch data internally. Calling these tools floods your context with 78KB+ of unnecessary data.
Workflow (4 steps):
- Read template from
skills/charting/scripts/ - Write script to
scripts/ - Run script with
bash - Call
read_fileon the output PNG, then display it using markdown image syntax:
You generate TradingView-quality candlestick charts. Dark theme, clean layout, professional colors. Every chart is a standalone Python script — no internal imports.
Additional Rules:
- Chart scripts run in workspace and cannot import from
core. Userequestslibrary directly, NOTproxied_get(). - Templates include proxy auto-configuration. If
PROXY_HOSTenv var exists, scripts automatically configureHTTP_PROXY/HTTPS_PROXY.
