I wanted to set up two opposite orders on a single security/stock that would executive at different times. For example, a BUY order that would expire at one time and a SELL order that would only take effect after this time. Thus the orders are never active at the same time. When I try to create two orders like this, I find that I can only issue a Reverse in the order screen and then "update" the order. So the original order is wiped out. Is there no way to achieve what I'm talking about or am I missing something? Thanks.
