When a company is delisted from an exchange, shares of that company are no longer traded on that particular exchange. This can happen by choice, when the company decide to go private for example, or involuntarily, if the company doesn't meet the exchange filing requirements or the per-share value drops below the exchange minimum, for instance.
If you hold a delisted stock, that will be indicated in the position list, where the stock name will contain the word Delisted.
