Not-able-to-create-an-OnClose-order-in-Interactive-Brokers

Hello,

here, in WealthLab I work on a strategy which sells at the close price. I use an exit on close to do that.

However, in Interactive Brokers I was not able to create such an order. It seems to me that they don't offer an "OnClose" order. So, the best I can do is to create a normal selling order for the day and as start time I set 2 minutes before the stock exchange closes.

But as this is not the perfect solution, I want to ask you, if anybody of you was / is able to create an "OnClose" order in Interactive Brokers?

Thank you in advance,
Werner
