Charting

⚠️ 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_file on the output PNG, then display it using markdown image syntax: ![Chart description](output/filename.png)

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. Use requests library directly, NOT proxied_get().

Templates include proxy auto-configuration. If PROXY_HOST env var exists, scripts automatically configure HTTP_PROXY/HTTPS_PROXY.
