- Plot the historical theta for a put option: stocks/load <SYMBOL>/options/grhist -p -g theta
- Plot the historical vega for a call option with a specific OCC option symbol: stocks/load <SYMBOL>/options/grhist -c CHAIN_ID -g vega
- Display raw data for historical gamma with a limit of 10 rows: stocks/load <SYMBOL>/options/grhist -g gamma -r -l 10
- Plot historical premium using the Intrinio data source: stocks/load <SYMBOL>/options/grhist -g premium --source Intrinio
- Export historical rho data to a csv file: stocks/load <SYMBOL>/options/grhist -g rho --export csv
- Save historical IV data to a specific excel sheet: stocks/load <SYMBOL>/options/grhist -g iv --sheet-name Sheet1
