Your portfolios, with how many lots each holds. Deliberately unpriced: valuing every portfolio to render a list would fan out to the market data for each one. Fetch a single portfolio to have it valued.

What happened to a requested ticker that no longer trades. "delisted": the company has no current US listing, so the answer is its history. "renamed": the company now trades as successorTicker, its current US presentation ticker (possibly another share class). A listed series (short volume, short interest, off-exchange volume, fails-to-deliver, congressional trades) is the retired ticker's own; a company-level read is the company's data.
