They say there are no stupid questions, just stupid people -- in which case, I'd often be carrying my stupid sign. Here is a question I have that relates to some rather basic terminology. First, what exactly is an "open order?" Is an open-order one that is open to be filled, yet has not been filled? If I have a limit order and a stop order "open" but neither has been filled, they are considered open orders, right? Now, if I put in a market order and it gets filled, is that an open order or has that order been closed and filled? Thanks!
