What it does

For each stock ticker you provide, the Actor:

1. Fetches historical OHLC data (end-of-day US market data)
2. Calculates technical indicators locally (no extra API calls needed):
   • SMA (Simple Moving Average) — short & long period with crossover detection (Golden Cross / Death Cross)
   • EMA (Exponential Moving Average) — short & long period
   • RSI (Relative Strength Index) — overbought/oversold detection
   • MACD (Moving Average Convergence Divergence) — with signal line crossovers
   • Bollinger Bands — volatility and price position analysis
3. Generates an overall signal: STRONG BUY, BUY, NEUTRAL, SELL, or STRONG SELL
