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.
Phil you are so far ahead, mate!
I am stuck at the very beginning. I cannot load the data.
The very first instruction in the Fundamentals capstone project reads:
Let’s start with loading in our newly created partitioned database which was created at getenv[
HOME],“/fundamentals_capstone_dbs/”`.
1.1 Load into the current process the database that was created
I tried this command without success:
\l $HOME/fundamentals_capstone_dbs/ \l ./db/fundamentals_capstone_dbs/
As part of the initialization we created a partitioned database with the following tables:
trade
- contains all the trade detailsspread
- Contains the option spread definitionsnbbo
- Contains the National Best Bid Offer quotes for each option
None of these tables have been created after loading the data so I guess my commad for loading the data has some error.
But where?
Thank you so so much for reaching out to me.
I have poted my question in the community as well.
Gratefully,
Angelica
PS I work for a consultancy firm and some of my colleagues want to learn qdb+. I am supposed to inspire them and I get stuck so so easily. Not even chatgpt could help me!
You can use either of below commands
\l ${HOME}/fundamentals_capstone_dbs or system"l ",getenv[`HOME],"/fundamentals_capstone_dbs/"
