  Capstone Fundamental Ex 1.5

  Posted by pravigak on October 11, 2023 at 12:00 am

  refServiceHandle: hopen `::5010
  **1.5 Using the handle `refServiceHandle` and the `uniqueOpts` variable we created before, call the
  `getOptionRef` API and retrieve the associated Options Reference data. Store the returned table
  in a variable `optRef`.**

  optRef: refServiceHandle(`getOptionRef;uniqueOpts)

  Using this line of code is not working. IPC says blocked. How do I fix it?

  I notice for your uniqueOpts variable you’ve declared it as:

  uniqueOpts: enlist (select distinct option_id from trade)

  Tables are created out of lists, so by enlisting the option_id column you are creating a list of a list.

  Since we already have our list, we just want to convert this into a list format. To do this you can use the exec  keyword.

  Once you’ve edited this, it should work fine.

  Thanks,

  Megan
