All, I have been unable to see where I can execute a bracket order on IB that is percentage based rather than a dollar amount. Ideally, I want to be able to enter short orders at market price with brackets that are percentage based and not dollars. These would be submitted just prior to the market opening. I would also like the ability to create a buy order (closing out the position) at market price at end of day in the event the bracket conditions on either side are not met. Does IB have this capability? If not, what trading platform does?
