Track multi-currency exposure risk
“Show me the exchange rate time series for USD to JPY, CAD to USD, and EUR to USD over the last 90 days so I can track how our foreign currency exposure has shifted.”
Build forex performance comparison chart
“Can you grab the historical exchange rate data for AUD to USD over the last 2 years with all the snapshots and percent changes? I want to plot it and compare it against our investment returns.”
