Jim,
If you use a market order, it get's filled at whatever the market price is at that time. When the market moves, your order, if unfilled gets another shot at the new market price (whether you want it to or not....).
You probably used a limit order, which get filled ONLY at the price you specify, even when the market moves. If you don't get all you want at the limit, and the market moves, you stay at that price until it comes back, or you cancel.
I suggested to Pat that she NOT use market orders, because she feeds the personal pockets of the MM's that way. They make a fortune on market orders, and can do anything they like to you (and do). |
