I see that options are an instrument type choice on NT8 but so far don't see any instructions on how to create them.
I tried selecting instruments from the menu, then add, put AAPL__150805C00127000 for master instrument, chose option for type, chose default and OPRA for exchanges, and entered AAPL 150508C00127000 for IB in the symbol map field. This created an instrument, but the instrument didn't work when I tried to make a chart with it.
Thanks for any help you can give.
