We are discussing two separate issues. The Fidelity rule stated is simply a lapse policy. If you have a GOOG call .01 in the money (the OCC policy for auto exercise) and you do not tell your broker to lapse, the option will be exercised. This is an important point for high priced or high volatile stocks. If you expect the market to open down on Monday, .01 in the money GOOG options doesn't guarantee a profit and in fact could be a significant loss. The thread author is asking what other brokers have as a policy for when they liquidate in the money options that will create a cash deficit in a cash account. Do they liquidate the option on Friday (and when) or do they liquidate the stock on Monday.
