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.

bash

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:

bash

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) < 10:
    df = fetch_ohlc(coin_id)
if df is None or len(df) < 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

coin_id	Symbol	Chart Color	Data Source
bitcoin	BTC	#F7931A	Yahoo Finance → CoinGecko
ethereum	ETH	#627EEA	Yahoo Finance → CoinGecko
ripple	XRP	#00AAE4	Yahoo Finance → CoinGecko
sui	SUI	#6FBCF0	Yahoo Finance → CoinGecko
gold	XAU	#FFD700	Yahoo Finance
silver	XAG	#C0C0C0	Yahoo Finance

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:

text

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)

Installation

Terminal bash


openclaw install charts
