MOC/MOO orders using the IB Plugin

Is it possible to submit special order types such as Market on Close and Market on Open via the IB plugin?

Obviously these order aren't supported directly, but I thought I might be able to use a workaround, such as sending a market order at a particular time in order to participate in the opening/closing auctions. I suspect however, that the plugin will return a "market closed" error. Anyone tried this?

I am curious about this as well. Have you ever figured out a way to do this?
Just issuing a market order at the open/close time isn't the same thing...

Market on Close and Market on Open order types are not supported, but I think they can be indeed simulated by sending a market order right before the close or after the open.
