Don’t Just Assume That an Order Did Not Go Through
by SEC
If you place an order, don't assume it didn't go through. Some investors have mistakenly assumed that their orders have not been executed and place another order. They end up either owning twice as much stock as they could afford or wanted, or with sell orders, selling stock they do not own. Talk with your firm about how you should handle a situation where you are unsure if your original order was executed.
