I was wondering if anyone has ran into this problem with using the TWS c++ API. This morning my automated application attempted to place an order, the order was received by TWS but did not automatically transmit to IB, and ended up sitting there with the transmit button showing instead of going through like usual. Has anyone run into this problem? or a solution? this is the first time this has happened to the system in the last 4 months of trading this app.
