What it does

Autonomous trading agent that uses the Coinbase Advanced Trading API to execute trades, analyze markets, and manage positions. It is designed to operate without human confirmation, making decisions based on technical indicators and sentiment data. It emphasizes maintaining a HODL Safe portfolio separate from the Default trading capital and follows a structured phase-based workflow for data collection, position management, and new entries.

How it works

• It operates as an autonomous trader with access to the Coinbase Advanced Trading API and MCP tools. It is instructed to call MCP tools directly (e.g., list_accounts, get_product_candles, create_order) rather than running build or reading documentation files.
• It uses an integrated analysis approach by recommending the use of analyze_technical_indicators and analyze_technical_indicators_batch for fetching candles and computing indicators, and it uses wait_for_market_event for event-driven monitoring rather than polling with sleep.
• It follows a phased workflow:
  • Phase 1: Data Collection (portfolio check, pair screening, market data collection, technical and sentiment analysis)
  • Phase 2: Manage Existing Positions (if any) with SL/TP checks, trailing stops, and rebalancing
  • Phase 3: New Entries (signal aggregation, position sizing, fees/profit checks, liquidity checks, and order execution)
  • Phase 4: Report and loop back
• It enforces a strict state management schema stored in .claude/trading-state.json, with fields for session, openPositions, tradeHistory, performance metrics, and risk assessments.
• It explicitly documents trading configuration rules, including a safeguard: never move funds from HODL Safe to Default portfolio. The Default portfolio balance is treated as the trading budget.
• It requires the operator to start with a fresh or resumed session as per its session-start decision logic (phases/session-start.md).
• When performing actions, it references specific tools and commands as described in the SKILL, such as get_portfolio, list_accounts, get_product_candles, analyze_technical_indicators, and wait_for_market_event.

What it can touch

• It interacts with the Default portfolio and HODL Safe portfolios via portfolio/account related MCP tools.
• It queries market data and performs indicator calculations via MCP indicator tools (e.g., calculate_rsi, calculate_macd, etc.).
• It executes trades using MCP trading actions (e.g., create_order).
• It reads and updates trading state stored in .claude/trading-state.json.

Caveats

• The skill is designed to operate autonomously; no human confirmation is required for trades.
• It enforces a hard rule to never move funds from the HODL Safe to the Default portfolio.
• It relies on external data sources for sentiment (Fear & Greed index and news sentiment) and may apply modifiers to signals based on those inputs.
• It requires proper API access and running MCP server state; the instructions specify the MCP server is already running and tools are available now.
• It does not provide guarantees of profitability and relies on the proper functioning of the indicator tools, sentiment sources, and market conditions.
