In this context, quotes come from two possible sources - your financial institution / brokerage or Quicken's quote suppliers.
Your FI is (to my knowledge) only going to report on holdings you actually own, so I can't see them providing "nonsensical and actually non-existing quote values".
Quicken's data suppliers work solely off of ticker symbols and the program's requests are identified as limited to securities you own and securities identified as being on your watch list.
IS THAT IT? Are these securities being shown in your portfolio view because you have them checked as on your Watch List. Look at your Security List (Ctrl-Y) to see. You could also exclude the Watch List 'account' from the portfolio view. <Back to regular commentary.>
So if these options have some form of a ticker symbol that might be misconstrued and Quicken thinks you own shares, you could conceivably get bad quotes, but I'm doubtful.
As to deleting the the bad prices, Edit the Security Details, More button, Edit Price History. Select the prices you want to delete, Click Delete. (But these are NOT being listed in your portfolio view because they have prices - good or bad).
Can you please capture one or more images of the parts of your Quicken window showing the issue, sensitive information blacked out as necessary to protect your privacy but annotated to describe the situation, and attach the image(s) here?https://community.quicken.com/discussion/7867159/faq-how-do-i-post-a-screenshot-in-the-community-from-windows

epkellner said: Thanks, Sherlock, but I am doing all that you recommend already. The options show zero balance, but stay in the line-up. Closed out equities do hide, but not the options.
epkellner said: The problem isn't new, I've meant to ask this for years. Upon downloads of new transactions from my brokerage account Quicken windows pop up asking if a given item is the same as xyz when it is the same company but a different strike price or a different exp date. So I have to answer numerous such pop-up windows one by one, which is kind of annoying, but .... I wonder if other option traders see the same or is there a specific trick. Options are not traded only in whole numbers, so decimals do not come into play, Perhaps I should ask Quicken programmers or make suggestions to improve their product?
epkellner said: I do not enter transactions prior to import and downloads use symbols, not Cusip #. The options downloads don't match, except for the underlying stock symbol, but not strike or expiration date, yet it asks "is it the same as (same stock but different strike or expiration) - one should think the algorism should figure it out that it is not a match. This is in addition to the fact that my holding list is way too long because of all the zeroed out option positions still showing.
epkellner said: @q_lurker -- thanks for the tip and it appears this problem is long-term and the conclusion seems to be to live with it (as far as the matching goes). I still don't see an answer as to hiding or deleting positions showing 0 balance (in options only - as the stock positions hide ok).
