trading

Makes a single daily BUY/SELL/HOLD decision for one stock on a given target_date by querying an offline DuckDB via MCP tools. The skill is driven externally: each invocation handles exactly one (symbol, target_date) pair and upserts the result into an action-list JSON file. Data access is via the `trading_mcp` server, which reads from an offline DuckDB. The same skill powers both backtest-style replay (caller loops over historical dates) and live trading (caller passes today's date, or omits it so the skill uses the latest date available in DuckDB). Use this skill whenever the user asks you to make a trading decision for a single stock on a specific date, run a live trading step, or append one record to a trading action list — phrased as "trade AAPL on 2025-03-05", "decide TSLA today", "run trading for MSFT 2025-04-10", or just "trade NVDA".
