Before placing an order you better should check whether the stock is in danger of getting soon suspended or even get delisted!... Here are some useful links for testing for pending delisting, and also researching SEC filings for the reasons etc.: https://listingcenter.nasdaq.com/IssuersPendingSuspensionDelisting.aspx https://www.sec.gov/edgar/searchedgar/companysearch OTC tickers: https://www.otcmarkets.com/research/stock-screener (click on "Download Data" to get a CSV list) https://stockscan.io/otc-stocks If a ticker gets delisted then it usually moves to the OTC market (Over-The-Counter) under a new ticker and continues trading there. BUT: the options usually continue using the old underlying ticker, but the options become "Non Standard" (NS), meaning only current holders can continue trading it... If you have other such related useful links (for example for NYSE, AMEX etc), please post here. The first link above is for NASDAQ tickers pending delisting or suspension.
Here's an example showing the recent delisting process of NSTG. The new ticker is NSTGQ (see announcement below). As said, the options become Non Standard (NS) and continue using the old ticker (NSTG). Example about NSTG stock delisting and moving to OTC (was announced on 2024-02-05-Mo, effective for 2024-02-14-We, ie. in 10 days or so): https://www.sec.gov/ixviewer/ix.htm.../1401708/000140170824000019/nstg-20240205.htm
How to make practical use of the above said information and facts: Since such a pending delisting has first to be announced by the exchange, and then takes about 10 days, it means trading DTE < 10 would be relatively safe... (depending on the strategy)
