Skill: charts

Purpose

Generate professional technical analysis charts with candlesticks, Fibonacci retracement, moving averages (SMA 20/50), RSI, and pattern detection. Uses the local crypto_charts.py module.

When to Use

• Boss Man asks "show me the BTC chart" or "run TA on silver"
• You need visual charts for market analysis or reporting
• Morning protocol chart generation
• Any request for technical analysis with visuals

Generate All Charts (Full Suite)

Generates charts for all 6 tracked assets: BTC, ETH, XRP, SUI, Gold, Silver. Warning: Takes 2-3 minutes due to API rate limits between requests.

cd ~/clawd && python3 -c "
import json
from crypto_charts import generate_all_charts, cleanup_old_charts
cleanup_old_charts()
report = generate_all_charts(output_dir=os.path.expanduser('~/clawd/charts'))
print(json.dumps(report, indent=2, default=str))
" 2>&1

Charts saved to: ~/clawd/charts/chart_btc.png, chart_eth.png, etc.

Generate Single Chart

For a quick single-asset chart without waiting for the full suite:

cd ~/clawd && python3 -c "
import os, json
from crypto_charts import (
    fetch_yfinance, fetch_ohlc, fetch_market_data,
    calc_moving_averages, calc_rsi, calc_fibonacci,
    detect_patterns, generate_chart, COINS
)

coin_id = 'COIN_ID'  # bitcoin, ethereum, ripple, sui, gold, silver
info = COINS[coin_id]

# Fetch data (Yahoo Finance first, CoinGecko fallback)
df = fetch_yfinance(coin_id)
if df is None or len(df) \x3C 10:
    df = fetch_ohlc(coin_id)
if df is None or len(df) \x3C 10:
    df = fetch_market_data(coin_id)

if df is not None and len(df) >= 5:
    df = calc_moving_averages(df)
    df = calc_rsi(df)
    fib = calc_fibonacci(df)
    patterns = detect_patterns(df)

    chart_path = os.path.expanduser(f'~/clawd/charts/chart_{info[\"symbol\"].lower()}.png')
    generate_chart(coin_id, df, fib, chart_path)

    print(f'Chart: {chart_path}')
    print(f'Price: \${df[\"close\"].iloc[-1]:,.2f}')
    print(f'RSI: {df[\"rsi\"].iloc[-1]:.1f}')
    print('Patterns:')
    for p in patterns:
        print(f'  - {p}')
else:
    print('Not enough data to generate chart')

Tracked Assets

What the Charts Include

• Candlestick bars (green up / red down) — 90 days of daily data
• 20 SMA (blue) and 50 SMA (gold) — trend and support/resistance
• Fibonacci retracement levels (0%, 23.6%, 38.2%, 50%, 61.8%, 78.6%, 100%)
• RSI subplot (purple) — with overbought (70) and oversold (30) lines
• Current price marker — dot + horizontal line in the asset's accent color

Pattern Detection (Automatic)

The module auto-detects and reports:

• SMA crossovers (Golden Cross / Death Cross)
• Head & Shoulders / Inverse H&S
• Fibonacci zone positioning
• Trend strength (7-day momentum)
• RSI condition (overbought/oversold/neutral)
• Price position within 90-day range

Sending Charts via Telegram

After generating, send the chart image using Clawdbot's native message command:

message (Telegram, target="7887978276") [attach ~/clawd/charts/chart_btc.png]

Rules

• Charts use 90 days of history — enough for meaningful TA
• Yahoo Finance is tried first (free, reliable), CoinGecko is fallback
• Rate limit: 8-second delays between coins, 20-second batch cooldowns
• Always run cleanup_old_charts() first to avoid disk buildup
• Chart images are ~150 DPI, dark theme (#0f172a background)
