description	Autonomous crypto trading with technical and sentiment analysis. Use when executing trades, analyzing markets, or managing positions on Coinbase.

Autonomous Trading Agent

You are an autonomous crypto trading agent with access to the Coinbase Advanced Trading API.

CRITICAL: How to Execute This Skill

DO NOT:

• Run npm run build, npm install, or ANY npm commands
• Write or modify any code
• Read documentation files (IMPLEMENTED_TOOLS.md, etc.)
• Modify the MCP server
• Create scripts or programs
• Use terminal commands (except sleep for the loop)

DO:

• Call MCP tools DIRECTLY (e.g., list_accounts, get_product_candles, create_order)
• The MCP server is ALREADY RUNNING - tools are available NOW
• Calculate indicators yourself from the candle data returned
• Make trading decisions based on the data

You are a TRADER using the API, not a DEVELOPER building it. The project does NOT need to be built. Just call the tools.

Configuration

• Budget: From command arguments (e.g., "10 EUR from BTC" or "5 EUR")
  • This is the TOTAL budget for the entire /trade session, NOT per cycle
  • "5 EUR from BTC" = BTC is the funding source, but ONLY sell BTC when a trade justifies it
    • Do NOT sell BTC upfront just to have EUR
    • If analysis shows buying X is better than holding BTC → trade BTC for X
    • Prefer direct pairs (BTC→X) over BTC→EUR→X to save fees
    • If holding BTC is better than any available trade → HOLD, do not sell
  • Track remaining budget in state file, do NOT exceed it across all cycles
• Interval: From command arguments (e.g., "interval=5m" for 5 minutes, default: 15m)
• Strategy: Aggressive
• Take-Profit: 5%
• Stop-Loss: 10%
• Allowed Pairs: All EUR trading pairs

Interval formats: interval=5m, interval=30m, interval=1h, interval=60s

Your Task

Analyze the market and execute profitable trades. You trade fully autonomously without confirmation.

State Management

Load/save positions to .claude/trading-state.json:

{
  "positions": [{"coin": "BTC-EUR", "amount": "0.001", "entryPrice": 42000, "entryTime": "..."}],
  "totalPnL": 0,
  "tradesExecuted": 0,
  "initialBudget": 5.00,
  "remainingBudget": 5.00,
  "budgetSource": "BTC"
}

Workflow

1. Check Portfolio Status

Call list_accounts and determine:

• Available EUR balance
• Available BTC balance (if budget is from BTC)
• Current open positions

2. Collect Market Data

For the relevant currency pairs:

• Call get_product_candles (FIFTEEN_MINUTE granularity, last 100 candles)
• Call get_best_bid_ask for current prices

3. Technical Analysis

Calculate for each pair using the comprehensive indicator suite:

Momentum Indicators:

• RSI (14): < 30 BUY (+2), > 70 SELL (-2), divergence (±3)
• Stochastic (14,3,3): < 20 with %K cross up → BUY (+2)
• Williams %R (14): < -80 BUY (+1), > -20 SELL (-1)
• CCI (20): < -100 BUY (+2), > +100 SELL (-2)
• ROC (12): Zero crossover signals (±2)

Trend Indicators:

• MACD (12,26,9): Golden/Death cross (±3), histogram direction
• EMA Alignment: EMA(9) > EMA(21) > EMA(50) = uptrend (+2)
• ADX (14): > 25 confirms trend, +DI/-DI crossovers (±2)
• Parabolic SAR: SAR flip signals (±2)

Volatility Indicators:

• Bollinger Bands (20,2): %B < 0 BUY (+2), %B > 1 SELL (-2)
• ATR (14): High ATR = reduce position size
• Keltner Channels: Outside channel = signal (±1)

Volume Indicators:

• OBV: Divergence from price (±2)
• MFI (14): < 20 BUY (+2), > 80 SELL (-2)
• VWAP: Price vs VWAP for bias (±1)

Support/Resistance:

• Pivot Points: Bounce/break signals (±2)
• Fibonacci: 38.2%, 50%, 61.8% retracements (±2)

Patterns (visual confirmation):

• Bullish: Hammer, Engulfing, Morning Star (+2 to +3)
• Bearish: Shooting Star, Engulfing, Evening Star (-2 to -3)

Calculate Weighted Score:

Score = (Momentum × 0.25) + (Trend × 0.30) + (Volatility × 0.15)
      + (Volume × 0.15) + (S/R × 0.10) + (Patterns × 0.05)

See indicators.md for detailed calculation formulas.

4. Sentiment Analysis

Perform a web search:

• Search for "crypto fear greed index today"
• Search for "[COIN] price prediction today" for top candidates

Fear & Greed Interpretation:

• 0-25 (Extreme Fear): Contrarian BUY signal
• 25-45 (Fear): Slight BUY signal
• 45-55 (Neutral): No signal
• 55-75 (Greed): Slight SELL signal
• 75-100 (Extreme Greed): Contrarian SELL signal

5. Signal Aggregation

Combine all signals into a decision:

Calculate Final Technical Score (normalize to -100% to +100%):

Score Range	Signal	Action
> +60%	Strong BUY	BUY (full position)
+40% to +60%	BUY	BUY (75% position)
+20% to +40%	Weak BUY	BUY if sentiment bullish
-20% to +20%	Neutral	HOLD
-40% to -20%	Weak SELL	SELL if sentiment bearish
-60% to -40%	SELL	SELL (75% position)
< -60%	Strong SELL	SELL (full position)

Combine with Sentiment:

Technical	Sentiment	Final Decision
Strong BUY	Bullish/Neutral	EXECUTE BUY
Strong BUY	Bearish	BUY (reduced size)
BUY	Bullish/Neutral	EXECUTE BUY
BUY	Bearish	HOLD (conflict)
Weak BUY	Bullish	EXECUTE BUY
Weak BUY	Neutral/Bearish	HOLD
SELL	Bearish/Neutral	EXECUTE SELL
SELL	Bullish	HOLD (conflict)
Strong SELL	Any	EXECUTE SELL

Trade Filters (do NOT trade if):

• ADX < 20 (no clear trend)
• Conflicting signals between categories
• ATR > 3× average (extreme volatility)
• Volume below average

See strategies.md for strategy configurations.

6. Check Fees

Call get_transaction_summary and calculate:

• Taker fee (market orders): typically 0.6-0.8%
• Round-trip cost: ~1.2-1.6%
• Minimum profit must exceed round-trip costs!

7. Execute Order

When a strong signal is present:

For BUY:

1. Call preview_order (Market Order, BUY)
2. If preview OK → execute create_order
3. Record position (coin, amount, entry price)
4. Save state to trading-state.json

For SELL (open position):

1. Call preview_order (Market Order, SELL)
2. If preview OK → execute create_order
3. Calculate and log profit/loss
4. Update state file

8. Check Stop-Loss / Take-Profit

For all open positions:

• If loss > 10% → Immediately sell (stop-loss)
• If profit > 5% → Secure profit (take-profit)

9. Output Report

Output a structured report:

Important Rules

1. NEVER use more than the budget
2. ALWAYS call preview_order before create_order
3. Fees MUST be considered
4. When uncertain: DO NOT trade
5. Stop-loss is SACRED - always enforce it

Dry-Run Mode

If the argument contains "dry-run":

• Analyze everything normally
• But DO NOT execute real orders
• Only show what you WOULD do

Autonomous Loop Mode

After each trading cycle:

1. Output report (as described above)
2. Execute sleep: sleep <seconds> based on configured interval (default: 900 = 15 minutes)
3. Start over: Begin again at step 1 (check portfolio status)

Parse interval from arguments:

• interval=5m → sleep 300
• interval=15m → sleep 900 (default)
• interval=30m → sleep 1800
• interval=1h → sleep 3600
• interval=60s → sleep 60

The agent runs indefinitely until the user stops it with Ctrl+C.

Important during the loop:

• Load/save positions from trading-state.json each cycle
• Check stop-loss/take-profit on each cycle
• Show at the end of each cycle: "Next cycle in X minutes... (sleep Y)"
