Answer:
The order has not yet been executed which means you still own 500 share
Step-by-step explanation:
The status of your order is that the order has not yet been executed which means you still own 500 share because despite that you own the 500 shares of ABC stock in which the stock has been declining in price but now sells for $30 per share in which you wanted to sell all the shares thereby placing a limit sell order at a price of $30 per share but the shares continue to decline from $30 per share to $29 per share to $18 per share, their wont be any cause for alarm because the order has not yet been executed which means that the 500 shares is still in your custody.
