    Newbie question

    Ah, it makes sense now. It seemed odd at first to list a price for expired, worthless options. But the price they traded at just prior to expiration is useful.

    Newbie question

    I have a newbie question. The NASDAQ option chain has a column labeled "date." Is this the expiration date of the option? If so, why does it list dates prior to today's date? Aren't those options expired, and now worthless? For example, see http://www.nasdaq.com/symbol/aapl/option-chain

    Python or C++

    Python is more suitable for one-off scripts and rapid development. It's very useful as "glue" to connect programs together, parsing inputs and the like. But for performance and scalability, C++ is the way to go. A compiled C++ program will often run 10x faster than a comparable Python program.
