使函数可以处理您感兴趣的每种回调类型。

def error_handler(msg):
    print (msg)

def execDetails(msg):
    print('ID',msg.execution.m_execId,'PRICE',msg.execution.m_price)

def commReport(msg):
    print('ID',msg.commissionReport.m_execId,'COM',msg.commissionReport.m_commission)

tws = Connection.create(port = 4001, clientId=123)
tws.register(execDetails, message.execDetails)
tws.register(commReport, message.commissionReport)
tws.register(error_handler, 'Error')
tws.connect()

您应该等待connect()完成，我通常只在准备就绪时使用nextOrderId回调通知我，但是在python中您可以sleep（2）或在这种情况下，我使用的是笔记本，因此我稍后才运行下一个单元格。

fx = Contract()
fx.m_secType = "CASH" 
fx.m_symbol = "USD"
fx.m_currency = "CAD"
fx.m_exchange = "IDEALPRO"
#tws.reqMktData(1,fx,"",False)

ord = Order()
ord.m_orderType = 'MKT'
ord.m_totalQuantity = 100000
ord.m_action = 'SELL'
tws.placeOrder(123,fx,ord) #increment this every order

此打印

ID 0001f4e8.57427bd9.01.01 PRICE 1.31565
ID 0001f4e8.57427bd9.01.01 COM 2.6313`

别忘tws.disconnect()了
