There are some trades done before any quotes. So when using aj I get some empty values for the columns bid and ask.

Hi ,

Thanks for raising.

In the real world there should be quotes before trades. I assume given this is an exercise, the data has been randomly generated across a time period and hence you are seeing the above.

I wouldn’t be too concerned, as long as you can see how aj works with some other option_id that’s what matters.
