Hi all,

Am new here and am attempting to retrieve historical options data. I've followed the steps described at 

https://www.quantconnect.com/docs/research/historical-data

but when I call the GetOptionHistory() method in the same manner as the documentation, I get an error stating "No method matches given arguments for GetOptionHistory". I've looked around the forums and attempted to find the documentation for the GetOptionHistory() method but have not managed to find some documentation or a forum post regarding this issue. Could anyone kindly advise? Thank you.
