Example prompt: Can you pull the daily EUR to USD exchange rate OHLC data for the last 100 trading days using Alpha Vantage FX Daily?

## When to prefer this

Use this endpoint when you need historical daily OHLC (open/high/low/close) forex exchange rate data for a specific currency pair. Ideal for building charts, backtesting FX strategies, or analyzing currency trends over days or months. Prefer this over intraday endpoints when daily granularity is sufficient and over weekly endpoints when you need more frequent data points.
