Automated Stock Trader

Fully automated weekly stock-picking and portfolio rebalancing system. Every Friday after market close, a KMeans clustering engine downloads S&P 500 OHLCV data, computes technical indicators (RSI, Bollinger Z, ATR%, MACD histogram, Garman-Klass volatility), clusters stocks across multiple named strategy configs, and writes optimized portfolio weights to S3. Every Monday before market open, a broker task reads those picks and rebalances an Alpaca account: liquidating stale positions, selling overweight holdings via market orders, and buying underweight holdings via limit orders. Both tasks run as scheduled ECS Fargate containers triggered by EventBridge cron rules.
