Please specify if the order is a market order or not and indicate any special terms
of execution (e.g., "all or none").
Important: Always specify if this order cancels or
replaces an existing order. We cannot cancel an order unless you ask us to, and
any losses that may result from uncanceled orders will be charged to your
account. Similarly, please specify if you are simply changing the price of a
previous order, since failure to do so could result in a duplicate order
for which you would be responsible.
