Ah, it finally worked.

Thank you very much for the advice!

Hi megan,

I tried a couple of sorting but seems I lose the partition on option_id no matter how I do.

Do you expect it? Or are there any ways to keep the partition?

I tried this way but didn’t work as it changed the format.

Is this the correct way to do it?

This is what I do

tradeContext:aj[option_idtime;select from trade where date= max date;select option_id,time,ask,bid from nbbo where date= max date]

The trade table is the original one.

It works now!

Thank you very much

No, it doesn’t.

I tried sing out/sign in again, a different browser, delete browsing history but none of them works.
