Functions named "Start API" occur in the official IB APIs but in InteractiveTradeR, this functionality is implimented implicitly by other functions such as create_new_connections(). Therefore, there is no need to ever call start_api() in InteractiveTradeR -- doing so will produce an informative error message.
start_api()
Other utilities:
active_connection_parameters(),
clean_slate(),
create_new_connections(),
disconnect(),
read_sock_drawer(),
