Agreed. I feel that if a question is going to be about a "real world" situation like trading stocks, it should reflect real world constraints that should be stated up front. I also found it curious that the example listed the stock price at 1 AM. It would be far more of a real world example to only consider times during the normal trading hours. A question phrased about a particular real-world domain that doesn't makes sense within that domain just doesn't seem fair to ask. But again, total nitpick on my part. The actual format in which the questions were presented was generally done well, and a nice refresh from the typical "interview prep" sites.
